Abstract

Система с использованием газлифта при механизированной эксплуатации скважины низкого давления содержит центральную колонну насосно-компрессорных труб в стволе скважины, имеющую конец устья скважины и конец отстойника скважины; кольцевое затрубное пространство, проходящее вокруг центральной колонны насосно-компрессорных труб между концом устья скважины и концом отстойника скважины; источник сжатого газа; газопровод для газлифтного газа, соединяющий источник сжатого газа со стволом скважины; газовый компрессор, имеющий вход и выход, причем выход соединяется с кольцевым пространством; выкидной трубопровод, соединенный с концом устья скважины центральной колонны насосно-компрессорных труб; и автоматически управляемый дроссель эксплуатационной скважины в выкидном трубопроводе. Такая система позволяет повысить эффективность добычи газа и нефти в скважинах.A system using gas lift for mechanized operation of a low-pressure well contains a central tubing string in a wellbore having a wellhead end and a well settler end; an annular annulus extending around the central tubing string between the end of the wellhead and the end of the well sump; compressed gas source; a gas lift gas pipeline connecting the compressed gas source to the wellbore; a gas compressor having an inlet and an outlet, the outlet being connected to the annular space; a flow line connected to the end of the wellhead of the central tubing string; and an automatically controlled production well choke in the flowline. Such a system improves the efficiency of oil and gas production in wells.
