Abstract

Газожидкостный сепаратор (19) для отделения свободной воды на забойной позиции газовой скважины содержит центробежный сепаратор (37) в трубчатом участке (23), образующем входное отверстие (27) газа и выходное отверстие (29) газа. Выше по потоку от центробежного сепаратора (37) трубчатый участок (23) оборудован множеством дренажных отверстий (47), через которые свободная вода, центрифугированная на трубчатый участок (23), входит в кольцевую трубу (33), обеспечивающую слив собранной воды под действием силы тяжести. Выше по потоку от дренажных отверстий (47) размещен струйный насос (51). Струйный насос (51) приводится в действие потоком газа для создания разрежения в трубе (33) и отсасывания обратно газа, вошедшего в трубу (33) через дренажные отверстия (47). Газожидкостный сепаратор (19) не имеет движущихся частей и исключает необходимость мониторинга или регулировки процесса разделения.
