HIGH-SPEED SUBMERSIBLE PLANT FOR OIL PRODUCTION FROM WELLS WITH HIGH GAS CONTENT

摘要

FIELD: oil and gas industry.;SUBSTANCE: plant comprises a submersible centrifugal pump, a submersible electric motor with hydraulic protection and a gas separator. The submersible centrifugal pump comprises at least one impeller with the area of impeller channel section calculated using two ratios. Vapours of friction of the pump, the gas separator, the hydraulic protection and the motor are made of wear-resistant materials.;EFFECT: expanded working zone of a pump and provision of its stable operation in low-debit wells with high gas content with optimisation of energetic characteristics of a pump.;2 cl, 5 dwg
