METHOD FOR RELEASING SURPLUS PRESSURE FROM INTERTUBE SPACE IN OPERATING IMMERSED ELECTRIC PUMPS Russian patent published in 1997 - IPC

Abstract RU 2081998 C1

FIELD: oil industry. SUBSTANCE: method refers to electrically-driven centrifugal, spiral and diaphragm pumps. Increased oil production and prolonged service life of electric motor and electric cable are achieved due to installing jet-type pump on pump-and-compressor tubing above steady-state dynamic level. This pump is pumping out gas from intertube space when produced liquid is passing through it. EFFECT: high efficiency. 1 dwg
