Description

Technical Field

[0001] The utility model belongs to the technical field of submersible electric pump unit installation, and in particular relates to a submersible electric pump dual-motor installation tool. Background Art

[0002] The electric submersible pump lifting technology for machine-drilled wells is the main production method in my country's offshore oil fields. As the displacement of oil wells becomes larger and larger and the depth of oil wells becomes deeper and deeper, the power of electric pump units is also increasing, and the motors of submersible electric pumps are also becoming longer and longer. Therefore, high-power submersible electric pump motors now tend to use two-section or even three-section motors in series; the connection between the motors of the submersible electric pump units adopts the plug-in docking method. If the docking operation or communication with the lifting equipment operator is improper, the pins and sockets may be damaged by collision during the docking process, causing the motor to be scrapped and returned to the factory, resulting in property losses; the present invention proposes an efficient and safe solution for the connection of the motor of the submersible electric pump unit.
