METHOD AND DEVICE FOR GAS CONDENSATE INVESTIGATION OF WELLS Russian patent published in 1997 - IPC

FIELD: gas and oil industry. SUBSTANCE: method relates to well development of gas and gas condensate fields and regulation of operating modes of production wells. At each steady state mode, well product is directed to set of separation units through swirling member. Swirled flow of well product is directed to separation unit where due to incline angle of slots in perforated pipe union additional swirling of flow takes place. After discharge from slots at tail part, flow enters expansion chamber where swirling is continued. Liquid and hard phases are withdrawn into containers for collection. Dry gas is directed to gas flow rate meters, through individual pipeline it goes to general gas field product collector. Prior to stabilization of all hydrodynamic parameters, performed are regular measurements of pressure and temperature. Degree of filling containers is determined by pressure gauge, liquid and hard phases are regular bypassed by means of gate valves to measuring tanks 9 during entire steady state mode of operation. Operating period is checked by stopwatch. When steady state mode of operation comes, recorded are values of steady state pressure, temperature, gas flow rate and amounts of gas condensate, water and mechanical impurities during period of operation in this mode. Then dry gas sample is taken. Certain amount of gas condensate in steam phase created in measuring tank is withdrawn through safety branch line from site of investigation and utilized. EFFECT: high efficiency. 3 cl, 4 dwg
