INSTALLATION FOR SURFACE PUMPING OF GAS-LIQUID MIXTURE Russian patent published in 2020 - IPC F04F5/54 

FIELD: pumps building.

SUBSTANCE: present invention relates to the field of pumping units intended for surface pumping of a gas-liquid mixture, including with its further injection under high pressure into an oil reservoir. Proposed plant comprises pump communicated via fluid injection line with ejector, fluid feed line, gas supply line supplied to ejector intake chamber, gas-liquid mixture discharge line and flow control means. Liquid supply line is made with bypass. Pump and ejector are installed on bypass. As adjustment means there used are electric valves and electric shutters. Electric valves are arranged at the ejector inlet and gas-liquid mixture discharge line. Electric shutters are located at the input and output of the bypass between the input and output of the bypass, on the gas supply line and on the gas-liquid mixture discharge line after the bypass output. Gas feed line, gas-liquid mixture discharge line and bypass at pump and ejector outlets are equipped with check valves. Flow meters are arranged at pump inlet and gas feed line.

EFFECT: technical result consists in simplicity of design, in providing flexibility of gas-liquid mix supply in a wide range of values, in improvement of installation ease, mobility and maintenance of the plant.
