Title:
TANK LOADING SYSTEM AND DUAL-ELECTRIC SUBMERSIBLE PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/124230
Kind Code:
A1
Abstract:
Disclosed by the present application are a tank loading system and a dual-electric submersible pump device, applied to the technical field of dual-electric submersible pump devices for oil well development. The dual-electric submersible pump device comprises an upper pump assembly and a lower pump assembly; the tank loading system comprises a tank body and a connector assembly; the tank body is provided with an accommodating cavity and a connecting hole in communication with the accommodating cavity; the connector assembly is disposed passing through the connecting hole; one end of the connector assembly is located in the accommodating cavity and used for being electrically connected with a first power supply cable, and the other end of the connector assembly is disposed outside the accommodating cavity and is electrically connected to a lower pump electrical cable. In a well completion process, the first power supply cable is electrically connected to the other end of the connector assembly in the tank loading system, the lower pump cable introduces an electrical cable wire into the tank loading system by means of the connector assembly; thus the shape requirements and the operation requirements of the lower pump cable are both reduced, while the probability that the lower pump cable is damaged due to small space is also reduced, and low well completion efficiency is increased. In the technical solution of the present application, the connector assembly is arranged in the tank loading system, and the technical problem of low well completion efficiency because of the lower pump cable being prone to damage during descent into the well is solved.
