СПОСОБ ВОЛНОВОГО ВОЗДЕЙСТВИЯ НА ПРОДУКТИВНЫЙ ПЛАСТ

摘要

FIELD: oil production, particularly enhanced recovery methods for obtaining hydrocarbons. ^ SUBSTANCE: method involves installing plunger sucker-rod pump in well filled with liquid, wherein the pump is connected to remote drive through control rod; creating isolated chambers in well; performing intermittent pressure change in separate chambers as plunger reciprocates; periodically communicating chambers having different liquid pressures with each other after full plunger reciprocation drive unloading as plunger reaches extreme upper position during downward plunger movement under gravity when control rod stress is highly decreased. ^ EFFECT: increased wave action power due to elimination of impact-and-dynamic equipment load. ^ 1 dwg
