GAS SEPARATOR AND METHOD OF ITS OPERATION Russian patent published in 2002 - IPC

FIELD: equipment applicable in oil production, more specifically, separators for gravitation separation of immiscible fluids with different densities. SUBSTANCE: gas separator includes sedimentation vessel. Its upper part has holes for passing the tubing string and discharge of separated gas, and through holes, in upper part of its side surface which form perforated tube of some height. During operation, lower part of sedimentation vessel contains fluid. Fluid upper level is variable within selected part below holes of perforated tube. Above separator level, upper part of sedimentation vessel is filled, mainly, with gas. Vessel is provided with pressure pump for connection with tubing string. According to said method, separator is installed at well bottom, and regulating valve is installed in gas line. Dynamic level of well is determined. Dynamic level inside separator is transferred to below zone of holes in perforated tube due to operation of regulating valve. Fluid level in separator is maintained within preset variation boundaries. EFFECT: higher efficiency of gas phase separation from two-phase mixture of fluid and gas during well operation. 12 cl, 5 dwg
