Description

Drilling tool make-up device and have its iron roughneck

Technical Field

The invention relates to the technical field of petroleum drilling, in particular to a drilling tool buckling device and an iron roughneck with the same.

Background

At present, with the development of oil drilling, wellhead hydraulic oil tools (such as power drill pipe tongs, power casing tongs, iron roughneck and the like) with high mechanization levels are more and more widely applied. Drilling tools need to be connected in the operation process of a drilling platform, a hydraulic elevator is usually used for clamping a drilling tool with the length of about 28.5m to hang over a wellhead, the drilling tool positioned in the wellhead is arranged right below the hydraulic elevator, a male connector at the bottom of the hanging drilling tool needs to be buckled with a female connector at the top of the drilling tool in the wellhead when the connection is carried out, and at present, problems exist in the buckling operation: 1. the gravity center of the drilling tool deflects when the hoisting is finished; 2. the working environment is severe, and wind force often acts on the suspended drilling tool; 3. sloshing of the swimming system. The above causes the drilling tool to continuously shake, so that the male connector at the bottom of the suspended drilling tool cannot be buckled with the female connector at the top of the drilling tool in a well.

At present, in order to solve the above problems, a manual auxiliary operation or a button-making operation by a drill floor manipulator is generally used. The drilling platform surface manipulator is independent heavy equipment and is used for grabbing and pushing a drilling tool on the drilling platform surface so as to finish the buckling operation. Because the space of a drilling platform is limited, the conventional drill floor manipulator has large volume, is interfered with other equipment, occupies large space and often has insufficient installation space. The problem that the potential safety hazard and the operating efficiency are lower exists in the manual auxiliary operation.

Therefore, there is a need for a drilling tool buckling device with high safety and high operation efficiency and an iron roughneck with the same.
