Electric submersible motor docking device

Abstract

The invention relates to the field of oil exploitation, and particularly discloses an electric submersible motor docking device. The electric submersible motor docking device comprises docking assemblies. The docking assemblies comprise supporting frames used for supporting first sub electric submersible motor bodies of an electric submersible motor and first driving parts which are fixedly connected with the corresponding supporting frames. The first driving parts can push the supporting frames to vertically move upwards so that the first sub electric submersible motor bodies located on the supporting frames can be driven to move towards second sub electric submersible motor bodies above the first sub electric submersible motor bodies. According to the electric submersible motor docking device, the phenomenon that inserting pins are damaged due to bumping in the docking process of the two sections of the sub electric submersible motor bodies of the electric submersible motor can be effectively avoided, and thus the one-time docking tripping success rate of the two sections of the sub electric submersible motor bodies is effectively increased.

Description

technical field [0001] The invention relates to the field of oil exploitation, in particular to a docking device for a submersible motor. Background technique [0002] During the construction of the electric submersible pump well, the submersible motor is formed by docking multi-joint submersible motors at the wellhead. The operation of two adjacent submersible motors is difficult when docking. It is necessary to ensure that the splines and The spline sleeve connection must also ensure that the three-phase pins of the motor enter the pin slots. [0003] At present, when the two-section submersible motor is docked, the operator usually directly operates the workover rig to lower the upper motor and connect the lower motor. The operation process depends entirely on personal operating experience. Because the hook lowering speed of the workover rig is difficult to control, and the brakes of some equipment are not sensitive enough, and the cooperation between the operator and th...

AI Technical Summary

Problems solved by technology

Because the hook lowering speed of the workover rig is difficult to control, and the brakes of some equipment are not sensitive enough, and the cooperation between the operator and the driller is required, it is difficult to accurately control the lowering position of the upper motor. The phenomenon that the motor pins are often damaged, and because the electrode pins cannot be replaced on site, it often causes rework, which seriously affects the construction progress.

[0004] In view of the deficiencies of the above-mentioned prior art, in order to avoid the phenomenon of the two-section submersible motor of the submersible motor from being damaged during the docking process, those skilled in the art are eager to seek a docking device for the submersible motor. In order to improve the success rate of docking two submersible motors in one trip
