Application July 19,` 1952, Serial No. 299,859

2 Claims... (Cl. 16e- 115)v This invention relates to a means of controlling a port (opening and closing said port)` through which certain materials are moved in an oil well. This material may be gravel forV gravel packing purposes, the gravel being entrained in a stream of mud. The materialsv may also be` certain chemicals when chemically treating a well, or fluid-under pressure for cleaning a well, etc.

An object of my invention is to provide a novel rotatably mounted port control sleeve which can be rotated within a tubular body to either open or close a port to permit certain materials to be moved through this port, as-may be necessary.

A featureof my invention is to provide a novel packing means on the rotatable sleeve which will effectively seal off the port in the tubular body, when the port in the rotatable sleeve is out of alignment with this port in the tubular body.

Another feature of my invention is to provide a square packing in the rotatable sleeve, this square packing surrounding the outlet port in the tubular body in one position of the rotatable sleeve. This square packing effectively sealing off the outlet port in the tubular body and preventing leakage at this point.

Other objects, advantages and features of invention may appear from the acompanying drawing, the subjoined detailed description and the appended claims.

In the drawing:

Figure 1 is a longitudinal sectional View of a gravel packing tool embodying my invention and showing the rotatable sleeve in open position.

Figure 2 is a fragmentary longitudinal sectional view of the body portion or" a gravel packing tool and showing the rotatable sleeve in closed position.

Figure 3 is a side elevation of the rotatable sleeve.

Figure 4 is a side elevation of the rotatable sleeve taken at right angles to Figure 3.

Figure 5 is a fragmentary side elevation of the operating and packing member.

Figure 6 is a sectional view taken on line 6--6 of Figure 5.

Figure 7 is a sectional view taken on line 7 7 of Figure 1.

My rotatable port control sleeve may be used in connection with a tool as described in application, Serial No. 216,192, filed March 17, 1951, for Hydraulically Operated Port Control Device, now abandoned, or in application, Serial No. 201,573, tiled December 19, 1950, for Hydraulic Slip Setting Means for Oil Well Tools.

In the gravel packing of oil wells the gravel is entrained with a muddy fluid which is pumped downwardly in the well through the drill pipe, and then passes outwardly through an open port in the gravel packingtool at the bottom of the well, and the gravel is then deposited around the liner while the fluid then returns upwardly to the ground surface. The gravel laden fluid passes outwardly from an open port in a movable piston within the tubular body of the oil well tool, thence through the open port in the body of the tool and then drops to its resting place at the bottom of the well.

The lower end of the drill pipe. is a square section 1 whichis positioned within the tubular body 2 of the tool. A collar 3 is provided on the bottom of the square section 1 and this collary threads onto pipe 4 which in turn is attached to the top packing cup 5. This packing cup is of the usual rubber type and is expansible so as, to pack off against the wall of 'the tubular housing 2. A second packing cup 6,. similar in construction to the cup 5, is spaced below the. cup 5 and also engages and packs off against the wall of the tubular housing 2. A tail pipe 7 projects downwardly. from the lower cup 6 a suitable distance, and the returning fluid passes upwardly through the tail pipe and thence through suitable portsv to bypass the pipe 1, drill pipe 1 and coupling 3, since the return fluid must pass upwardly around the outside. of the. drill pipe, all of'which is usual and well known in the art.

The packing cups 5 and 6 are connected by a pipe-likesection S, which is provided with an upper bore 9 extending to a laterally extendinghole 10. The material which. is to be deposited passes downwardly through the drill pipe, thence into the pipe 4, then through the bore 9 and out through the hole 1t). The cups 5 and 6 will conxine and direct the material. to the particular area in which thev cups Sand 6 areV positioned.

A sleeve 11 is rotatably mounted within the.- body 2 of the tool and is confined between an upper shoulder 12 and a lower shoulder 13'. The sleeve 11 is provided with one or more ports 1d which can be aligned with outlet ports 15 in the body 2 of the tool. When the ports 14 and 15 are in alignment, as shown in Figure l, fluid flowing out of the hole 10 will pass outwardly and, for example, the gravel laden fluid will drop to the bottom of the well and will be deposited.

To rotate the sleeve 11 so that the ports 14 will align, or misalign with the ports 15, I provide a longitudinal spline or groove 16 on the inside of the sleeve which are engaged by ribs or flanges 17 on the pipe-like section 8, and thus rotating the sleeve 11 when the drill pipe is rotated. To govern the amount of the rotation of the sleeve, I provide an arcuate notch 18 which is entered by a lug 19 on the body 2, thus insuring that the sleeve 11 will either open or close the ports 15 in the tubular body. To seal oft the ports 15 when the ports 14 are misaligned therewith, I provide a square packing 20, this square packing fitting into a square groove 21 in the sleeve 11, and the square packing surrounds the port 1S in one position of the sleeve. Since two sides of the square packing 20 will be vertical, I find that the packing does not tend to press into the port 15 as the packing slides over the same during rotation of the sleeve 11. As a result, the square packing is not cut by the sharp edges of the port 15. Also the square packing 2f) will effectively seal off the port 15 from any possible fluid flow, either vertical or horizontal.

In operation the tool body 2, together with the packing cups 5 and 6 therein, is lowered into the oil well on the drill pipe. The weight of the outer tubular body 2 will hold that body in proper position so that the packing cups 5 and 6 are above and below respectively, the outlet ports 15 in the body 2. The blades, or ribs 17, are fitted in the grooves 16 and, consequently, the sleeve 11 can be rotated clockwise, or counter-clockwise, by appropriate rotation of the drill pipe.

When the tool is being run into the well, and also for testing purposes of the well, the ports 14 and 15 are misaligned, and the packing 20 will, therefore, surround the outlet port 15, sealing the same. When it is desired to flow material through the port 15, the sleeve 11 is rotated until the port 14 aligns with the port 15, this being determined by the stop lug 19. When a proper amount of material has been flowed into the well, the sleeve 11 3 can again be rotated to a position to close and seal the port 15.

Having described my invention, I claim:
