Description

Technical Field

[0001] The utility model relates to the technical field of male cone equipment, in particular to a male cone which is easy to adjust. Background Art

[0002] A male cone is a tool specially used for making buckles and salvaging from the inner holes of oil pipes, drill pipes, casing milling pipes, packers, water distributors, production distributors and other objects with holes. In geological drilling projects, the male cone is a commonly used salvage tool for salvaging the inner holes of pipe strings. According to the joint thread and the salvage thread specifications, it is divided into right-hand thread (positive buckle male cone) and left-hand thread (negative buckle male cone). Some male cones have chip grooves. The salvage thread is divided into serrated thread and triangular thread. When an accident occurs in the hole, the drill tool falls, falls off, or breaks into the hole, the male cone can be used for salvage operations.

[0003] The existing method of salvaging the fallen drill tools is to control the lifting and rotation of the male cone. When salvaging the drill tools, a large amount of stones and mud are easily accumulated in the hole. The traditional male cone cannot be pushed downward after entering the borehole, which makes it inconvenient to control the connection between the male cone and the drill tool. The salvage operation is difficult to achieve, which affects the salvage effect and speed in the hole.

[0004] Therefore, it is necessary to provide a new male cone that is easy to adjust to solve the above technical problems. Utility Model Content

The outer edge of the alloy block is flush with or retreats inwardly with the outer edge of the male cone body, so as to prevent the alloy block from damaging the drilling tool when pushed. The water injection pipe and the water outlet hole with a larger inner part and a smaller outer part are convenient for water injection operation, and it is convenient to clean up mud and sand impurities.
