Abstract

Настоящее изобретение относится к системе затрубных барьеров для заканчивания скважины со скважинной трубчатой металлической конструкцией, содержащей скважинную трубчатую металлическую конструкцию, содержащую первый затрубный барьер и второй затрубный барьер, причем каждый затрубный барьер введен и установлен в скважине так, чтобы примыкать к стенке скважины с созданием ограниченного пространства, имеющего ограниченное давление между стенкой, частью скважинной трубчатой металлической конструкции, первым затрубным барьером и вторым затрубным барьером, так что первый затрубный барьер изолирует ограниченное пространство от первого затрубного пространства, имеющего первое давление, а второй затрубный барьер изолирует ограниченное пространство от второго затрубного пространства, имеющего второе давление, причем система затрубных барьеров содержит модуль выравнивания давления, имеющий первое положение, в котором первое затрубное пространство сообщается по текучей среде с ограниченным пространством, и второе положение, в котором второе затрубное пространство сообщается по текучей среде с ограниченным пространством, причем в первом положении второе давление выше первого давления, а во втором положении первое давление выше второго давления.The present invention relates to a system of annular barriers for completing a well with a downhole tubular metal structure comprising a downhole tubular metal structure comprising a first annular barrier and a second annular barrier, each annular barrier being introduced and installed in the well so as to abut the wellbore to create a bounded space having limited pressure between the wall, part of the downhole tubular metal structure, the first annular barrier and the second annular barrier, so that the first annular barrier isolates the limited space from the first annular space having the first pressure, and the second annular barrier isolates the limited space from the second annular space having a second pressure, and the system of annular barriers comprises a pressure equalization module having a first position in which the first annular space is in fluid communication with a limited space and the second position, in which the second annulus is in fluid communication with the limited space, and in the first position the second pressure is higher than the first pressure, and in the second position the first pressure is higher than the second pressure.
