METHOD FOR OPERATING DEEP PUMP PLANT Russian patent published in 1996 - IPC

Abstract RU 2061175 C1

FIELD: oil production. SUBSTANCE: deep-well pump is lowered into well using sucker rods to predetermined depth. The pump is started up and mud is lifted to surface. Dynamogram is recorded in the process of pump operation. Then the pump is stopped for subsequent pumping viscoelastic composition and crush liquid in beyond string spacing. Density of viscoelastic is less than density of the mud. Then the pump is started. Amount of viscoelastic composition is determined on the base of expression presented. EFFECT: high efficiency. 6 dwg
