SYSTEM FOR TRANSPORTING GAS-WATER-OIL MIXTURE AT FIELD

摘要

FIELD: oil and gas production. ^ SUBSTANCE: system consists of line for supply of product from wells with two pipe branches for supply of gas saturated flow into jet pump coupled with separating installation and power block via system of pipelines. The pipe branches ensure division of gas-liquid mixture entering the jet pump from wells into a passive gas-saturated flow and passive liquid-gas medium. Also the passive gas-saturated flow enters an internal stepped channel of a hollow cylinder tube installed coaxially inside a nozzle of the jet pump and forming a circular nozzle of alternate cross section with its external surface and with internal surface of the nozzle along its whole length. The active flow of circulating water-oil mixture is supplied into the circular nozzle of alternate cross section from the separating installation by means of an electro-centrifugal pump via the internal channel of the tubing of the power block. ^ EFFECT: raised efficiency of installation. ^ 2 dwg
