Detailed Description
The full-diameter sleeve guide tool consists of an upper shell 1, a middle shell 2, a lower shell 3, an inner sleeve 4 and a guide body 5, wherein the upper shell 1 is arranged on the top of the middle shell 2 in a threaded manner, and the lower shell 3 is arranged on the bottom of the middle shell 2 in a threaded manner through the guide body 5; a water hole 13 is arranged in the lower shell 3. An inner sleeve 4 is movably arranged in the upper shell 1 and the middle shell 2, and a sleeve joint 6 is arranged above the upper shell 1 and used for connecting a pipe column. The sleeve joint 6 is fixedly connected with the inner sleeve 4. A centralizing bearing 9 is arranged between the upper shell 1 and the inner sleeve 4 through a sealing ring 7 and an annular gasket 8. The sealing ring 7, the annular gasket 8 and the centralizing bearing 9 are sequentially arranged from top to bottom; the centralizing bearing 9 has centralizing effect on the inner sleeve 4, and the sealing ring 7 has sealing effect and realizes limit of the centralizing bearing 9.
The lower end of the inner sleeve 4 is in a convex shape, and 4 spiral keys 10 are arranged on the circumference of the lower end of the inner sleeve 4. The screw key 10 is spirally arranged on the circumference of the lower end of the inner sleeve 4. The inner wall of the middle shell 2 is provided with a spiral groove 11 corresponding to the spiral key 10, and the middle shell 2 is in sliding and rotating connection with the inner sleeve 4 through the cooperation of the spiral groove 11 and the spiral key 10.
The circumference of the shoe-guiding body 5 of the full-diameter sleeve shoe-guiding tool is provided with 6 cutting teeth 12. Wherein 3 cutting teeth 12 are forward cutting teeth, and the other 3 cutting teeth 12 are reverse cutting teeth, so that the obstacle can be effectively destroyed by the cutting teeth 12 no matter the shoe body 5 rotates forward or reversely during operation (see figure 1).
The working process of the full-diameter sleeve guide tool is as follows:
the screw key 10 at the bottom of the inner sleeve 4 is located at the uppermost end of the screw groove 11 at the beginning, when the inner sleeve 4 runs down and encounters an obstacle, the shoe body 5 stops moving downwards when encountering the obstacle, and because the gravity of the inner sleeve 4 connected with the pipe column is far greater than the integral gravity of the upper shell 1, the middle shell 2, the lower shell 3 and the shoe body 5, the inner sleeve 4 and the sleeve joint 6 continue to slide downwards along the screw groove 11, thereby driving the upper shell 1, the middle shell 2, the lower shell 3 and the shoe body 5 to integrally rotate and providing a larger downward pressure and torsion force. During this rotation, the forward cutting teeth 12 on the shoe body 5 break obstacles such as sand bridge mud cakes.
When the screw key 10 is screwed down to the bottom of the screw groove 11, the inner sleeve 4 stops moving, at this time, the inner sleeve 4 is lifted up, and the screw key 10 moves up along the screw groove 1 and simultaneously integrates the upper shell 1, the middle shell 2, the lower shell 3 and the shoe-guiding body 5
The power of reverse rotation is provided, so that the upper shell 1, the middle shell 2, the lower shell 3 and the shoe guide body 5 integrally and reversely rotate, and reverse cutting teeth 12 on the shoe guide body 5 can destroy obstacles such as sand bridge mud cakes again during rotation, and the process is repeated until the obstacles are thoroughly destroyed, so that the sleeve is continuously and smoothly lowered.
This full latus rectum sleeve pipe guide instrument adopts full latus rectum structure, inside unpowered structure, through carrying the positive and negative rotation of the guide shoe body 5 of realization with putting down to interior sleeve pipe 4, simultaneously, lower casing 3 adopts 3 drillable material, very easily clears away the guide shoe after the obstacle and bores the work, avoided well cementation to bore turbine and screw rod part again after accomplishing, do not influence the work of opening the brill next time, the casing can continue to use as sheathed tube part after boring, the pipe efficiency of down of complex structure wells such as highly inclined well and horizontal well has been improved, time and cost have been saved.
