Definitions
- the present invention relates to a method for drilling underground inverted arcuate paths and installing production casings, conduits, or flow pipes therein.
- Prior methods of drilling the pilot hole have utilized sections of drill string which are of uniform external diameter. When joined together such sections produce a drill string of uniform external diameter having no external protrusions at the joints between the sections or elsewhere along the string. Such joints are relatively weak, and the entire drill string tends to frequently stick during the drilling of the pilot hole.
- Prior methods of reaming the pilot hole and installing the production casing have used a single reamer and required that powered means be provided to thrust the production casing into the hole.
- Prior attempts to draw the reaming apparatus or production casing through the hole with, for example, the drill string used in drilling the pilot hole have resulted in the drill string knifing through the soil and the reaming apparatus or production casing not following the original drilling path. In these methods it is also necessary to frequently interrupt the installation process in order to join additional sections of the production casing to the trailing end of the casing.
- the present invention provides apparatus and a method for installing production casings, conduits, flow pipes and the like underneath and spanning an obstacle such as a river.
- a directional drill attached to a drill string is advanced in an inverted arcuate path to form a pilot hole underneath the obstacle.
- a larger concentric washover pipe follows the advance of the drill at some distance behind the drill to form a concentric annulus about the drill string and enlarge the pilot hole.
- the preferred drill string of the present invention is made up of sections having external upsets at each end, making each drill string section of slightly larger external diameter at each end than in the middle.
- a drill string is produced with integral concentric collars formed by the upsets at each joint between the sections. This produces a stronger connection at each joint and during the drilling of the pilot hole the collars help size the hole and prevent the drill string from sticking in the hole as frequently as in prior methods.
- the leading end of the washover pipe is provided with cutting blades which enlarge the pilot hole to a diameter greater than that of the washover pipe. This produces an annulus between the enlarged pilot hole and the washover pipe.
- drilling mud is supplied through the inner annulus between the washover pipe and the drill string to entrain the cuttings dislodged by the cutting blades and return them through the outer annulus between the enlarged pilot hole and the washover pipe. This prevents the cuttings from accumulating within the washover pipe at its leading end and inhibiting its advance.
- a first reamer preferably a flycutter reamer, of larger diameter than the production casing is attached to the end of the washover pipe where it exits the drilling path;
- a second reamer preferably a floating reamer, having a relatively smaller leading end and a larger trailing end of smaller diameter than the first reamer and larger diameter than the casing is attached to the other end of the flycutter reamer by means, such as a section of washover pipe, providing for some separation between the two reamers; and the production casing is attached to the other end of the second reamer with a swivel.
- the end of the casing attached to the swivel is closed to prevent the entry of mud and cuttings during the reaming and installation operation.
- the casing joints have been previously welded together into a casing portion and the joints inspected and coated for corrosion resistance, so that the casing is in only one, or no more than a few, portions. This allows the casing to be installed in an almost continuous movement.
- the portions of the production casing may be supported in line with the pilot hole some distance above the ground on rollers placed beyond the exit point of the pilot hole.
- the exit point of the pilot string may become the entry point of the reaming apparatus and production casing.
- the reaming apparatus is rotated, and drawn through the pilot hole, typically by the washover pipe, followed by the non-rotating production casing.
- drilling mud is provided to exit at the first reamer and entrain the cuttings.
- two reamers are used and drilling mud may additionally exit at the second reamer.
- the mud supply system of the present invention is capable of supplying much more mud at a higher pressure than the supply systems of existing methods. This provides lubrication for the passage of the production casing and permits the reamers and production casing to be drawn through the hole without having the washover pipe knife into the soil and cause the reamers and production casing to leave the original drilling path.
- the first reamer enlarges the hole to a diameter greater than that of the second reamer and the cuttings dislodged by the first reamer are entrained in the drilling mud.
- This separation provided between the first reamer and the second reamer which follows it permits the cuttings to separate within the drilling mud and produces a more accurate hole than other methods.
- the smaller diameter second reamer forces the drilling mud and entrained cuttings into the annulus between itself and the sides of the enlarged hole to form a concentric ring of mud and cuttings around the interior of the enlarged hole while leaving a concentric opening within this ring for passage of the production casing.
- the ring of drilling mud and entrained cuttings acts as a bushing in the concentric annulus between the production casing and the hole to lubricate the advance of the even smaller diameter production casing. Since the leading end of the casing is closed, the mud and cuttings do not enter the casing.
- the remaining length of the first portion of the production casing outside of the hole is drawn along the rollers supporting it towards the point where the casing enters the hole. That part of the casing which is between rollers advances toward the hole horizontally, and that part of the casing which is between the rollers nearest the hole and the entry point of the hole bends due to gravity towards the entry point, advancing at a downward angle and entering the hole.
- the weight of this downward-angled part of the casing helps crowd the casing into the hole and reduces the force required to draw the reaming apparatus and following casing through the hole.
- This method of the present invention also permits joints of the production casing to be joined together into longer portions prior to the beginning of the reaming and casing installation process. This eliminates the need in existing methods to frequently interrupt the installation of the casing in order to join additional joints to the trailing end of the casing extending out of the entry point.
- the reaming operation may be performed without the production casing attached to the reaming apparatus, followed by a second reaming operation with the production casing attached in order to complete the installation.
- washover pipe is attached to the trailing end of the second reamer to provide a means for drawing the reaming apparatus and production casing through the enlarged hole in the second reaming operation.
- the production casing is attached to the trailing end of the second reamer as before and the reaming and installation process proceeds as described above.

- FIG. 1 The first operation of the present invention is illustrated generally in FIG. 1.
- a water course 10 drilling from a first position 12 on the surface of the ground at one side of the water course to a second position 14 beyond a structure 16 at the other side.
- the desired path is illustrated generally by dashed line 18, and can comprise either a constant radius arc or a path of complex curvature.
- a pilot hole is drilled along path 18 by a directional drill 20 powered by mud pumped through a trailing drill string 22 which extends through the drilled hole and exists at position 12.
- Directional drill 20 can be controlled according to the principles set forth in U.S. Pat. No. 3,878,903 for "Apparatus and Process for Drilling Underground Arcuate Paths.” Other directional drilling techniques could be used as well.
- Washover pipe 24 extends from a position substantially behind directional drill 20 to the entrance 12 to the drilled hole. Washover pipe 24 is of larger diameter than drill string 22 so that the washover pipe will fit circumferentially around the drill string within the hole. Washover pipe 24 is typically made of ordinary 5" or larger diameter drill pipe. During the drilling along arcuate path 18, a survey tool, of a type well known in the art, is periodically inserted within drill string 22 to a position immediately behind directional drill 20 to determine the current position of the directional drill.
- washover pipe 24 is not advanced until drill string 22 begins to stick in the hole. Drill string 22 is advanced a desired distance, or until it begins to stick, the advance of drill string 22 is halted while washover pipe 24 is advanced around drill string 22, the leading end of washover pipe 24 remaining some distance behind the leading end of drill string 22 at all times, then the advance of washover pipe 24 is halted while drill string 22 is again advanced until it begins to stick.
- an inclined drill rig 26 is positioned in a slanted hole 28.
- the forward surface 30 of hole 28 is normal to the initial direction of the path into the ground for ease in drilling the hole.
- drill string 22 A portion of drill string 22 is illustrated in more detail in FIG. 1A.
- Each section, such as that numbered 31, of drill string 22 has an upset 37 at each end, making each drill string section of slightly larger, e.g. about 3/8", external diameter at each end than in the middle.
- drill string 22 is produced with an integral concentric collar 35 at each joint 33 between the sections. This produces a stronger connection at each joint 33 and during the drilling of the pilot hole collars 35 help size the hole and prevent drill string 22 from sticking as frequently.
- Directional drill 20 has a leading drill bit 40 powered by drilling mud supplied through drill string 22. As drill bit 40 dislodges the earth along the desired arcuate path, these cuttings are entrained in the drilling mud which flows backwardly in the small annular space 42 surrounding drill string 22 and into and through annulus 46 between drill string 22 and washover pipe 24.
- washover pipe 24 is enlarged and provided with cutting blades 45 which enlarge the pilot hole to a diameter greater than that of the washover pipe. For example, if washover pipe 24 is of 5" diameter, cutting blades 45 may enlarge the pilot hole to a 71/2" diameter. This produces outer annulus 49 between the enlarged pilot hole and washover pipe 24.
- drilling mud is supplied through inner annulus 46 between drill string 22 and washover pipe 24 as shown by arrows 48. The drilling mud entrains the cuttings dislodged by cutting blades 45 and returns them through outer annulus 49 as shown by arrow 50. This prevents the cuttings from accumulating at the leading end of washover pipe 24 and inhibiting its advance.
- FIGS. 2A illustrates in more detail one method of advancing drill string 22.
- the trailing end of drill string 22 is attached to a chuck on drill rig 26.
- Drill rig 26 is advanced down ramp 52 as shown by arrow 55 to crowd drill string 22 into the hole. Drilling mud is pumped through conduit 53, through drill rig 26, and down through drill string 22 as shown by arrow 54.
- drill rig 26 is drawn back up ramp 52 to the position shown in FIG. 2A.
- Drill rig 26 is now ready for the attachment of another section of drill string to the trailing end of drill string 22 to again advance the drill string or for the attachment of another section of washover pipe to the trailing end of washover pipe 24 to advance the washover pipe.
- FIG. 2B illustrates in more detail one method of advancing washover pipe 24.
- the trailing end of washover pipe 24 is attached to a chuck on drill rig 26.
- Drill rig 26 is advanced down ramp 52 as shown by arrow 55 to crowd washover pipe 24 into the hole.
- Drilling mud is pumped through conduit 53, through drill rig 26, and down through washover pipe 24 as shown by arrow 57.
- drill rig 26 is drawn back up ramp 52 to the position shown in FIG. 2B.
- Drill rig 26 is now ready for the attachment of another section of washover pipe to the trailing end of washover pipe 24 to again advance the washover pipe or for the attachment of another section of drill string to the trailing end of drill string 22 to advance the drill string.
- washover pipe 24 is advanced to also exit at point 14. Drill string 22 is withdrawn from the pilot hole, leaving the washover pipe occupying the entire pilot hole from point 12 to point 14.
- first reamer 60 is attached to washover pipe 24 where the latter extends out the pilot hole at point 14.
- Second reamer 66 is attached to the other end of first reamer 60 by a section of washover pipe 64 to provide for some separation between the reamers.
- the reamers should be separated a distance of 5 to 15 times the diameter of the reamed hole. For a 36 inch hole, a separation of 30 feet provides good results.
- Production casing (or conduit or flow pipe) 70 is attached to the other end of second reamer 66 by a swivel 68 to prevent rotation of casing 70 during the reaming and the installation operation.
- casing 70 The leading end 69 of casing 70 is closed to prevent the entry of mud and cuttings during the reaming and installation operation. Since the hole sometimes contains water or mud, casing 70 may be weighted to neutralize its buoyancy so that it floats into the hole, facilitating its installation and minimizing any damage to the casing, as described in U.S. Pat. No. 3,894,402.
- the remaining length of the first portion of production casing 70 is supported in line with the pilot hole some distance above the ground on rollers 80 and 81 located beyond pilot hole exit point 14. Two rollers are shown, but more may be provided.
- the first portion of production casing 70 consists of a plurality of casing joints, such as those numbered 83, joined end to end.
- the first portion of production casing 70 may constitute the entire length of casing to be installed but this may be unwieldly. Hence, it may desirable to provide one or more additional portions of production casing, such as casing portion 82.
- Casing portion 82 is joined to the trailing end of casing portion 70 after most of casing portion 70 has been installed along reaming path 61. If necessary, additional portions of production casing like casing portion 82 may be fabricated.
- first reamer 60 is of a larger diameter than second reamer 66.
- first reamer 60 has a plurality of reaming teeth 62, as well as a plurality of ports 72 through which drilling mud exits to entrain the cuttings dislodged by the reamer.
- first reamer 60 is a flycutter reamer of relatively small length having longitudinal openings 59, as shown in FIG. 5, through which the drilling mud and entrained cuttings may pass into the enlarged hole. As shown in FIG.
- second reamer 66 has a smaller, typically frustoconical, leading end provided with reaming teeth 78. Ports 89 are optional and, when provided, provide further exits for drilling mud in addition to ports 72 in first reamer 60.
- second reamer 66 is a floating reamer of substantially neutral buoyancy in drilling mud weighing approximately 10 pounds per gallon so as to float through the enlarged hole.
- the trailing end of second reamer 66 is typically cylindrical and of smaller diameter than first reamer 60 and of larger diameter than production casing 70.
- first reamer 60 may be of 36" diameter, second reamer 66 of 30" diameter, and production casing 70 of 24" diameter.
- the reaming and production casing installation operation proceeds generally as is shown in FIG. 3.
- Washover pipe 24 is rotated and drawn through the pilot hole in the direction of arrow 75 by drill rig 26.
- Reamers 60 and 66 are rotated and drawn along reaming path 61 by the rotating washover pipe.
- Swivel 68 draws production casing 70 along behind second reamer 66 and prevents casing 70 from rotating with the reamers so that the casing is not subjected to the torsional stress which would be caused by rotation.
- Drilling mud is provided to flow from drill rig 26 through washover pipe 24 and exit at first reamer 60, and, optionally, at second reamer 66.
- the reaming apparatus and production casing are attached to the end of the washover pipe at point 14, but it should be understood that these may be attached to the end of the washover pipe at point 12, in which case the reaming and installation operation would proceed in the direction opposite the one illustrated in FIG. 3. This would, of course, require that drill rig 26, or one like it, be provided at point 14, rather than at point 12, as illustrated in FIG. 3.
- FIG. 4 The reaming and production casing installation operation is illustrated in more detail by FIG. 4.
- reaming teeth 62 of first reamer 60 enlarge pilot hole 77 to a diameter greater than that of production casing 70.
- Drilling mud 74 pumped through washover pipe 24 in the direction of arrow 76 exits through ports 72 in first reamer 60 (shown in FIG. 5) to entrain the cuttings dislodged by reaming teeth 62.
- the separation provided between first reamer 60 and second reamer 66 by the section of washover pipe 64 permits the cuttings to separate within the drilling mud in space 65 and produces a more accurate hole.
- Reaming teeth 78 on second reamer 66 further break up and separate the cuttings.
- an open passage may be provided through hub 67 of first reamer 60 such that some of the drilling mud 74 continues through hub 67 and section of washover pipe 64 to exit at optional ports 89 in second reamer 66.
- Second reamer 66 of a smaller diameter than first reamer 60 and a larger diameter than production casing 70, forces the drilling mud and entrained cuttings into annulus 71.
- the mud and cuttings form a concentric ring 63 around the interior of the enlarged hole while leaving a concentric opening 79 within this ring for passage of the even smaller diameter production casing.
- Production casing 70 of a smaller diameter than reamers 60 and 66, is drawn into the enlarged hole behind second reamer 66 by swivel 68. Swivel 68 prevents production casing 70 from rotating.
- the ring 63 of mud and cuttings acts as a bushing in the concentric annulus 73 between production casing 70 and the sides of the enlarged hole to lubricate the advance of production casing 70. Since leading end 69 of casing 70 is closed, the mud and cuttings do not enter the casing.
- rollers 80 and 81 depends on the strength and characteristics of the production casing. The distance must be short enough that the unsupported part of the production casing 86 which is between rollers 80 and 81 is not subjected to such stress due to its own weight that there is a risk of casing failure.
- the weight of the downward-angled part of the casing 88 which is between rollers 81 and point 14 helps crowd casing 70 into the hole and reduces the force required to draw the casing along reaming path 61. Advancement of casing 70 is further aided by the weight of that part of the casing 90 which is within the hole along the downward-angled portion of reaming path 61.
- casing portion 70 When most of the first portion of production casing 70 has been drawn into the hole, the trailing end of casing portion 70 is lifted off of rollers 80 and 81 and onto the ground, casing portion 82 is joined to the trailing end of casing portion 70, the casing is lifted back onto the rollers, and the reaming and installation process continues. Since casing portions 70 and 82 consist of many casing sections, such as those numbered 83, it is unnecessary to frequently interrupt the installation operation in order to join additional casing sections to the trailing end of the casing extending out of the hole.
- the reaming operation may be performed without production casing 70 attached to second reamer 66, followed by a second reaming operation with the production casing attached in order to complete the installation.
- a section of washover pipe 93 is attached to the trailing end of second reamer 66.
- additional sections of washover pipe, such as section 94 are joined to the trailing end of washover pipe section 93, to form washover pipe string 92. Sections of the leading washover pipe 24 are removed as they exit the hole at point 12.
- washover pipe string 92 functions as washover pipe 24 for purposes of the second reaming operation, which includes installation of the production casing and proceeds as described above and illustrated in FIGS. 3 and 4.
- washover pipe string 92 it is also possible to use washover pipe string 92 to draw the reaming apparatus back through the enlarged hole from point 12 to point 14 after the initial reaming operation is completed rather than transporting the reaming apparatus aboveground to point 14.
- the sections of washover pipe 24 which were removed at point 12 during the reaming operation are reattached to the now trailing end of washover pipe 24 at point 12, again providing a washover pipe 24 extending from point 12 to point 14 in enlarged hole 95.
- Sections of washover pipe string 92 are removed as they exit at point 14 and, when the reaming apparatus reaches point 14, washover pipe section 93 is removed.
- Swivel 68 and production casing 70 are attached to second reamer 66 and a second reaming operation including installation of the production casing proceeds as described above and illustrated in FIGS. 3 and 4.
- such a bushing may be formed by the first reaming operation, thereby facilitating the passage of the reamer and casing on the second reaming operations.
- the lubricity of the drilling mud being pumped through in the second reaming operation will greatly improve the ability to pull the casing through this tubular bushing.
- the presence of the bushing will help to seal the walls of the hole so as to improve the returns of the drilling mud, thereby providing lubrication of the casing throughout substantially its entire length.
