Abstract

1. Способ получения электроэнергии при эксплуатации нагнетательных и добывающих скважин, заключающийся в том, что размещение гидродвигателя и электрогенератора, соединенных между собой валом, ниже статического уровня жидкости в скважине и перекрытого кольцевого пространства между гидродвигателем и эксплуатационной колонной пакером, при доливе жидкости в скважину после достижения динамического уровня долив останавливают, после чего жидкость уходит в пласт, достигая статического уровня, жидкость, проходя через гидродвигатель, приводит его и электрогенератор в движение и вырабатывается электроэнергия, которая передается по электрокабелю на устье скважины, отличающийся тем, что движение жидкости с динамического уровня до статического происходит без приложения энергии извне, при этом кольцевое пространство между гидродвигателем и эксплуатационной колонной перекрыто пакером и жидкость, стремясь к статическому уровню, перетекает через гидродвигатель.2. Способ по п. 1, отличающийся тем, что после отбора насосом жидкости из скважины, до динамического уровня, насос останавливают, жидкость поднимается до статического уровня, при этом кольцевое пространство между гидродвигателем и эксплуатационной колонной перекрыто пакером и жидкость, стремясь к статическому уровню перетекает через гидродвигатель, который приводит в движение электрогенератор, вырабатывающий электроэнергию, передаваемую на устье скважины по электрокабелю.1. The method of generating electricity during the operation of injection and production wells, which consists in placing the hydraulic motor and electric generator interconnected by a shaft below the static liquid level in the well and the overlapped annular space between the hydraulic motor and the production string with the packer, while adding fluid to the well after reaching the dynamic level, topping is stopped, after which the fluid goes into the reservoir, reaching a static level, the fluid passing through the hydraulic motor, it and the electric generator are set in motion and electricity is generated, which is transmitted via an electric cable to the wellhead, characterized in that the fluid moves from the dynamic level to the static level without applying external energy, while the annular space between the hydraulic motor and the production string is blocked by the packer and the liquid, to a static level, flows through the hydraulic motor. 2. The method according to claim 1, characterized in that after the pump takes the fluid from the well to a dynamic level, the pump is stopped, the fluid rises to a static level, while the annular space between the hydraulic motor and the production string is blocked by a packer and the fluid tends to flow through the static level through a hydraulic motor that drives an electric generator that generates electricity transmitted to the wellhead through an electric cable.
