METHOD OF WELL PRODUCTION SEPARATION AND DEVICE FOR METHOD EMBODIMENT Russian patent published in 2003 - IPC

FIELD: oil producing industry; applicable, for instance, in technology of separation of well production lifted from well in form of gas-liquid hydrocarbon emulsion, particularly, in form of gas-water-oil emulsion. SUBSTANCE: method includes lifting of production from well in form of gas-liquid hydrocarbon emulsion and its heating; hydrodynamic treatment of production in turbulent conditions with breakdown of natural stabilizers of hydrocarbon emulsion; additional hydrodynamic treatment of production with provided hydrodynamic conditions of flow of liquid phase characterized by Reynolds number of not in excess of 10000. In this case, main amount of produced water and gas is separated from liquid hydrocarbon phase. Separation efficiency of gas from liquid hydrocarbon phase is regulated by pressure under which additional hydrodynamic treatment of production is carried out. Device for embodiment of claimed method includes pipeline for supply of production in form of gas-liquid hydrocarbon emulsion, production heating unit, unit of breakdown of natural stabilizers of hydrocarbon emulsion. This unit has narrowed part of pipeline, production flow converter in form of cylinder and expanded part of pipeline. Device is provided with additional converter of production flow in form of horizontal cylinder. The latter is made to ensure hydrodynamic conditions of liquid phase flow characterized by Reynolds number of not in excess of 10000 and located between unit of breakdown of natural stabilizers of hydrocarbon emulsion and unit for withdrawal of production phases. There is also unit for regulation of gas separation, which is made in form of cylinder. It is located above additional converter of production flow over its entire length, communicated with it over its length and has pipe-union at outlet. EFFECT: simplified method and device for its embodiment with possible prompt control of gas separation efficiency. 9 cl, 1 dwg
