Abstract
The invention relates to a well repair oil drill pipe provided with anti-torque shoulders. The well repair oil drill pipe is characterized by comprising an oil pipe body (1), a drill rod male joint (2) and a drill rod female joint (3), wherein oil pipe joints (4) are arranged at the two ends of the oil pipe body (1); one anti-torque shoulder (5) is arranged at the inner end of a screw thread at the right end of the drill rod male joint (2); the other anti-torque shoulder (5) is also arranged at the inner end of a screw thread at the left end of the drill rod female joint (3); the end face of the oil pipe joint (4) at the left end of the oil pipe body (1) is contacted with the anti-torque shoulder (5) of the drill rod male joint (2); and the end face of the oil pipe joint (4) at the right end of the oil pipe body (1) is contacted with the anti-torque shoulder (5) of the drill rod female joint (3). A structure in which the oil pipe body and the drill rod male and female joints are arranged is adopted, and the anti-torque shoulders are arranged, so that the oil drill pipe has the advantages of high tensile strength, high torsional strength, rapidness and convenience in buckling and unbuckling repeatedly, no damage to the screw threads, easiness and convenience in maintaining, and lower cost.
Description
Technical field
When the present invention relates to a kind of well workover, finish the oily drilling pipe of operations such as shaft bottom cleaning, pressure break, acidifying, brill match.
Background technology
Underground work is during for well workover, according to different requirements, usually to finish workover treatments such as shaft bottom cleaning, pressure break, acidifying, brill plug, usually use 2-7/8 " heavy wall tubing or 2-3/8 " macaroni, 2-7/8 during well workover " the withstand voltage height of heavy wall tubing; but the screw thread torsional strength is poor; and be not suitable for going up repeatedly shackle, go up shackle repeatedly often to cause the screw thread thread gluing to sprain 2-3/8 " tension of macaroni and torsional strength height, be fit to repeatedly go up the shackle operation, but expensive.Therefore seek a kind of tensile strength and torsional strength higher, it is quick and convenient and do not damage screw thread to go up shackle repeatedly, keeps in repair easyly, lower-cost well workover is particularly important with oily drilling pipe.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of tensile strength and torsional strength higher, it is quick and convenient and do not damage screw thread to go up shackle repeatedly, keep in repair easy, the oily drilling pipe of the lower-cost well workover that has antitorque shoulder.
The object of the present invention is achieved like this:
The oily drilling pipe of a kind of well workover that has antitorque shoulder, it comprises the oil pipe body, fillet of tool joint pins and tool joint box, the two ends of described oil pipe body are equipped with oil connection, described fillet of tool joint pins is connected with the oil connection of oil pipe body left end, described tool joint box is connected with the oil connection of oil pipe body right-hand member, the oil connection of the right-hand member of described fillet of tool joint pins and oil pipe body left end is provided with the screw thread of mutual coupling, the oil connection of the left end of described tool joint box and oil pipe body right-hand member is provided with the screw thread of mutual coupling, the left end of described fillet of tool joint pins and the right-hand member of tool joint box also are provided with the screw thread of mutual coupling, the threaded inner end of described fillet of tool joint pins right-hand member is provided with antitorque shoulder, the threaded inner end of described tool joint box left end also is provided with antitorque shoulder, the oil connection end face of described oil pipe body left end contacts with the antitorque shoulder of fillet of tool joint pins, and the oil connection end face of described oil pipe body right-hand member contacts with the antitorque shoulder of tool joint box.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention adopts the oil pipe body to add the structure of drill pipe box and pin, and has increased antitorque shoulder, makes that oily drilling pipe has tensile strength and torsional strength is higher, and it is quick and convenient and do not damage screw thread to go up shackle repeatedly, keep in repair easy, lower-cost advantage.
