Description

Technical Field

[0001] The utility model relates to pipe material processing, in particular to a clamping sleeve for eccentric pipe material processing. Background Art

[0002] With the advancement of science and technology and the development of exploration technology, oil and gas production has gradually shifted to unconventional oil and gas wells, deep wells, and deep seas, which has put forward higher requirements for downhole power drilling equipment. At present, in order to solve the problem of low mining efficiency, horizontal wells or cluster horizontal wells are widely used at home and abroad to increase the recovery area and improve the recovery rate. However, due to the weak soil layer and difficult construction, higher requirements are also put forward for the prediction of tool deflection ability and the prediction and control of wellbore trajectory.

[0003] In order to meet market demand, the structural curvature of screw drills must also be gradually enhanced. Structural curvature refers to the curvature of the curved shell of the screw drill. In the process of processing the curvature of the drill rod, an eccentric clamp is required. This application is proposed to meet the above demand. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a jacket for eccentric processing of pipe materials to solve the problems in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the technical solutions adopted are as follows:

[0006] A jacket for eccentric processing of pipe materials, comprising a jacket body, an upper edge ring formed integrally is arranged at the upper end of the jacket body, and an inner retaining ring formed integrally is arranged inside the lower end of the jacket body;

[0007] The sleeve body is provided with four slots, the upper ends of the four slots penetrate the upper edge ring, and the lower end of one of the slots penetrates the inner stop ring.

[0008] As a further improvement of the utility model, the outer diameter of the upper edge ring is larger than the inner diameter of the casing body, and the inner diameter of the inner retaining ring is smaller than the inner diameter of the inner wall of the casing body.

[0009] As a further improvement of the utility model, the outer wall of the sleeve body is in a conical structure in the axial direction, and the outer diameter of the sleeve body decreases from top to bottom.

[0010] As a further improvement of the utility model, four slots are opened along the axial direction at equally divided angles.

[0011] The beneficial effects of the utility model are:

[0012] The utility model has a simple structure and is specially used for clamping the end of a drilling tool for eccentric processing. The jacket is installed at the end of a pipe material, and the slot that runs through the inner retaining ring plays the role of clamping and positioning, wherein the positioning is mainly used for identification; the outer wall of the jacket body has a conical structure in the axial direction, which is conducive to clamping the pipe material, and there is no need to install a positioning piece or a limit piece.
