Claims (3)

1. Способ предотвращения замерзания устья нагнетательной скважины оборудованной колонной насосно-компрессорных труб (НКТ), включающий сообщение межтрубного пространства скважины с водоводом через клапан коленообразного трубопровода, работающий на закрытие со стороны нагнетания жидкости в скважину, отличающийся тем, что сообщение водовода с межтрубным пространством скважины осуществляют в подземной его части ниже уровня сезонного замерзания грунта.1. A method of preventing freezing of the mouth of an injection well equipped with a tubing string, comprising communicating the annular space of the well with a conduit through a bend valve, working to close from the side of the fluid injection into the well, characterized in that the conduit communicates with the annulus of the well carried out in the underground part below the level of seasonal soil freezing. 2. Способ по п.1, отличающийся тем, что в скважинах с высоким пластовым давлением, склонных к изливу при вынужденных остановках работы скважины, полость НКТ сообщают с затрубным пространством аналогичным клапаном, что и у коленообразного трубопровода, также ниже линии сезонного замерзания грунта, устанавливаемой на наружной стенке НКТ.2. The method according to claim 1, characterized in that in wells with high reservoir pressure, prone to spout during forced shutdowns of the well, the tubing cavity is communicated with the annulus by the same valve as the knee-shaped pipeline, also below the seasonal freezing line, installed on the outer wall of the tubing. 3. Способ по пп.1 и 2, отличающийся тем, что в качестве клапана для сообщения используют подпружиненный тарельчатый клапан.3. The method according to claims 1 and 2, characterized in that a spring-loaded poppet valve is used as a valve for communication.
