SUBMERSIBLE ELECTRIC PUMP SOLID PARTICLES AND GAS SEPARATOR Russian patent published in 2002 - IPC

FIELD: oil producing industry. SUBSTANCE: invention relates to design of submersible electric pumps intended for pumping out formation fluids with high content of mechanical admixtures and gas. Separator made as separate module is additionally installed on pressure branch pipe of submersible pump. Separator consists of ejector and conical-cylindrical hydraulic cyclone with tangential holes for taking in formation fluid. Hydraulic cyclone mechanical admixtures collecting chamber and ejector are made in one space in direction of fluid flow. To provided delivery of cleaned fluid, separator is connected with submersible pump inlet by feed pipeline laid along pump housing near motor supply cable. Pipeline is made oval-shaped to decrease cross-section of plant. EFFECT: increased service life of submersible pump without changing its design owing to separation of mechanical admixtures and gas from fluid delivered to pump inlet and using gas as additional lifting force in tubing. 3 cl, 4 dwg
