Abstract

Нефтяная скважина включает в себя ствол скважины (2) ниже уровня земли (4), идущий к нефтяному пласту (6). Ствол скважины включает в себя крепление (8) обсадными трубами, внутри которого расположен эксцентриковый винтовой насос (РСР) (10), имеющий впускное отверстие (12) в нижнем конце и своим верхним концом присоединенный к насосно-компрессорной трубе (14). Кольцевое пространство (16) определяется между насосом (10), трубой (14) и креплением (8). Кольцевое пространство сообщается с пластом и включает в себя напор (20) пластового флюида. Композиция на водной основе, содержащая необязательно сшитый поливиниловый спирт, может заливаться в кольцевое пространство (16) и перемещаться под действием силы тяжести в пласт (6) непосредственно перед впускным отверстием (12). Композиция может улучшать производительность и эффективность насоса (10) благодаря своей способности увеличивать подвижность нефти в пласте непосредственно перед насосом (10) и/или повышать способность нефти проникать во впускное отверстие насоса. Кроме того, за счет улучшения подвижности и/или уменьшения величины обратного давления при прохождении нефти через впускное отверстие насоса (или любое другое сужение) может быть увеличена скорость течения нефти из пласта в ствол скважины, что приведет к возрастанию нормы выработки нефти.
