METHOD OF OPERATING POOR DROWNED GAS CONDENSATE WELLS

摘要

FIELD: oil-and-gas production.;SUBSTANCE: proposed method comprises forcing hydrocarbons from productive bed bottom hole zone to bottom hole head by three-phase gas-fluid mix upward flow in oil-well tubing and directing it into oilfield line for integrated treatment for long distance transport. Well original ground is equipped with hydraulic pump and two receivers. Gas-fluid mix from well head is first injected into intake receiver top section filled with reservoir fluid separates at oilfield and, on discharging reservoir fluid from receiver bottom, into forcing receiver accelerated by hydraulic pump. Gas-fluid upward flow in oil well tubing is accelerated by reducing dynamic well head pressure. Frequency on injecting lower-pressure gas-fluid mix into top section of one of the receivers from well head and compressing it to pressure of bypassing into production line via spring-loaded piston valve is optimised with due allowance for operating volume of high-pressure receivers, hydraulic pump efficiency and increased output of well.;EFFECT: complete discharge of hydrocarbon condensate liquid phase and associated water to flame without well blow-out with combustion of liquid and gaseous hydrocarbons.;1 tbl, 1 dwg
