Abstract
A jet bit ensures precise drilling of holes through the earth's surface, such as drainholes around a well. The jet bit has front rotating orifices and jets to drill a hole in a medium larger than the diameter of the bit. The orifices directed to the rear provide thrust to propel the bit forward by enlarging the drainhole. A stationary shroud extends beyond the front orifices to maintain the front jets rotation. The jet bit may include turbine to control rotation rate and torque on front jets containing rotating shafts. A jet bit can be small enough to turn in a radius of four (4) inches from a vertical wellbore to create a horizontal drainhole. Various mechanical cutters can be mounted on the front of the jet bit to enable cutting with both jets and mechanical cutters.
Description
- This application claims priority of provisional application No. 61/743,025 filed on Aug. 24, 2012.
- 1. Field of the Invention
- This invention describes a jet bit for drilling drainholes in the earth and can be used for cleaning tubulars and other materials. One version contains a turbine for controlling rate of rotation of front jets and torque to rotate the shaft connected to the front orifices. One version can be turned in a short radius of four inches from vertical to horizontal for drilling drainholes in oil/gas reservoirs.
- 2. Description of Related Art
- Jet bits (Jet bits) and background for drilling drainholes are described in U.S. Pat. No. 4,790,394 (Dickinson et. al.); U.S. Pat. No. 5,853,056 (Landers); U.S. Pat. No. 6,206,112(Dickinson); U.S. Pat. No. 6,263,984 (Buckman); and U.S. Pat. No. 6,668,948 (Buckman).
- Currently no other jet bits exist that have rotating front jet bits that when connected to high pressure hose will turn in a radius of four inches or less from vertical to horizontal to drill horizontal drainholes. It is obvious that the Badger is too large and without a shield to keep the spinning jet bit away for the formation, the friction between the front of the jet bit and formation will cause the front to cease to rotate.
- What is needed is a jet bit that can be turned in a radius of less than four inches when connected to a high pressure hose. It needs to have a standoff to enable it to drill a hole through an oil/gas formation without the front of the jet bit ceasing to turn because of friction between it and the formation. It needs to drill drainholes through the earth having diameters large enough for the jet bit to pass through and large enough to allow the cuttings to pass outside the jet bit and the tubular to which the jet bit is attached. It needs to cut hard and soft reservoirs more efficiently and economically than current jet bits in use. The bit should also have thrust force so that it has its own motive force from rear thrusters.
- A rotary jet bit is provided that contains a turbine that controls the toque and rate of rotation of front jets and can be turned in a radius of less than four inches from vertical to horizontal to drill drainholes in oil/gas reservoirs. It is designed such that the rotating front jets have a standoff so that the front of the rotating bit will continue to turn and will not come into contact with the formation so that the front jets will continue to turn to continue jet drilling to produce drainholes in the formation and/or removing solid material solid materials from tubulars and other enclosures. The rotary jet bit comprises a non-rotating outer body consisting of inlet housing and a bearing housing connected to a high pressure fluid source; a rotating inner shaft in the outer body that is connected to and rotates a drill head that has orifices. It has a turbine consisting of an inlet of one or more stationary stator blades connected to the outer body and one or more rotating rotor blades attached to the rotating shaft that rotates the shaft connected to a high pressure drill head; a dynamic seal between the outer housing and the rotating shaft to prevent leakage of high pressure fluid past the rotating shaft to the exterior of the jet bit; and a bearing assembly in the bearing housing to transfer hydraulic and mechanical axial loads on the rotating shaft to the non-rotating stationary outer body; thus providing rotating straight jets on front of the drill head to provide more capable and efficient jet drilling than jet bits currently in use that use stationary straight jets or swirling full cone fluid jets.

FIG. 1 a contains the elements of a rotary jet bit whereas a rotatingshaft 12 turns inside anouter housing 10 with rotating shaft attached to cutting head withorifices 24 to enable the rotating front orifices to effectively drill and clean solid material. The jet bit has an inlet highpressure fluid connection 8 with an inlet housing 10 a bearinghousing 14 containingbearings 20 to enable the rotatingshaft 12 to turn relative to bearinghousing 14. At the front ofinlet housing 10 is aturbine 30 with stationary angled vanes to conduct the high pressure fluid into vanes into the rotating turbine to produce rotation of the rotatingshaft 12. This high pressure fluid passes through the turbine and through the hollow part of the cutting head and through cuttinghead orifices 24 that are rotating with the cutter head. Theseal 22 serves to reduce the leakage of fluid from the rotatingshaft 12 to the outside throughbearing exhaust 26; bearingexhaust 26 also reduces pressure on the bearings.Seal 22 can be a labyrinth seal, O-rings, metal seal (example; beryllium copper) and other configurations to contain the high pressure in the conducting channels from theinlet 8, through the turbine vanes and to theorifices 24. This rotary jet bit can be made of very small dimensions with total diameter of less than ½ inch and a length of less than one inch and sizes up to three inches in diameter with lengths greater than eight inches.FIG. 1 b has added to the elements ofFIG. 1 a therear orifices 28 that create high pressure jets to propel the jet bit forward and also cuts the material the jet bit is drilling to produce larger effective bores and to also improve the removal of cuttings from the drainholes.FIG. 2 illustrates the geometrical relation of the rotating shall 12 to theCutting Head 18 and illustrates that they are integrally connected and turn at the same rate. -
FIG. 3 illustrates that fluid flowing through the stationary inlet vanes of theturbine 30 impinges onto the rotatingvanes 32 to produce a rotation of the rotatingshaft 18. By sizing these vanes and changing their angles and using different flow rates the rate of rotation of the rotatingshaft 12 can be varied from very slow rotation, less than 10 revolutions per minute, to more than 10,000 revolutions per minute. The turbine vanes enable significant torque to power the jet bit turn even with significant frictional forces in the jet bit and/or debris in front of the jet bit.Seal 22 is a labyrinth rotating seal as illustrated inFIG. 4 that seals the high pressure fluid inside the jet bit from the low pressure fluid in the outside of the jet bit. This pressure differential is equal to the pressure drop across the orifices. The pressure drop across the labyrinth seal is created as a small amount of fluid leaks through a series of restrictions in the seal in turbulent flow. This fluid leakage flow passes throughbearings 20 and cools and lubricates them. Thebearing assembly 20 in thebearing housing 14 transfers the hydraulic and mechanical axial loads on the rotatingshaft 12 to the non-rotating stationary outer body. Acylindrical shroud 16 attached to the bearing housing typically extends beyond the front of thecutting head 18 such that the material being cut does not negatively influence the rotation of thecutting head 18. Advantages of the turbine powered jet bit are that the turbine is highly reliable, it can provide considerable torque and power to the rotating shaft and cutter head, and the rotary speed and torque of the turbine can be varied by the design of the turbine vanes, and by varying the flow rate and the pressure differential across the turbine. -
FIG. 4 illustrates the flow of liquid through the seals with a small amount flowing on the outside to of the bearings. -
FIG. 5 a consists of an embodiment that has the same elements as the jet rotary turbine powered jet bits inFIG. 1 b with the turbine vanes removed. In this rotary jet bit the torque produced on the cuttinghead 18 and therotating shaft 12 is by the reaction of the torque generated by the fluid through the orifices located on thecutter head 18. The rear jets due toorifices 28 will provide thrust to propel the jet bit forward and the high pressure jets will also cut the material to make a larger equivalent drainhole.FIG. 5 a has the same elements asFIG. 5 b without therear orifices 26. In this case the jet bit is attached to a tubular and pushed forward by the tubular force atconnection inlet 8. -
FIG. 6 consist of aprotector cap 34 that is placed on the jet bit to protect the head from debris and allow clearance through sharp transitions. Theprotector cap 34 is a water soluble material that dissolves away and does not to disrupt cutting operations. -
FIG. 7 is similar toFIG. 5 b with the addition of mechanical cutters 40 also on front of the jet bit to enable the bit to cut both with high pressure jets and also mechanical cutters such as polycrystalline diamond (PDC), tungsten carbide, silicon carbide, or silicon nitride. - Let us now consider one preferred embodiment of the turbo jet drill used to jet drill drainholes in wells in the earth.
