OIL PRODUCTION PLANT Russian patent published in 2004 - IPC

Abstract RU 2243415 C2

FIELD: oil producing industry.

SUBSTANCE: invention can be used in wells with high content of gas and mechanical impurities for pumping out oil with submersible pumps. Said well oil production plant includes auxiliary tube with end insulating device lowered into well and pump lift installed inside. Holes are made in upper part of auxiliary tube under flowing level to communicate with well annulus. Spaces of lift and auxiliary tube at surface communicate with vacuum compressor to withdraw gas. Invention is aimed at enlarging operating capabilities of submersible pumps handling liquids containing gases and mechanical impurities.

EFFECT: improved reliability and increase service life of plant.
