Abstract

Изобретение относится к морскому способу для подготовки скважины для добычи углеводородсодержащих текучих сред из ствола скважины, в котором устанавливают буровую платформу для бурения по меньшей мере части ствола скважины; бурят первую часть ствола скважины; устанавливают первую обсадную колонну; соединяют буровой противовыбросовый превентор с верхней частью первой обсадной колонны, например посредством устьевой арматуры; бурят вторую часть ствола скважины; устанавливают эксплуатационную обсадную колонну, имеющую первую концевую часть, наиболее близкую к верхней части первой обсадной колонны, и вторую концевую часть, причем эксплуатационная обсадная колонна содержит множество затрубных барьеров, и каждый затрубный барьер имеет трубчатую металлическую часть, установленную как часть эксплуатационной обсадной колонны, и разжимную металлическую муфту, окружающую трубчатую металлическую часть и имеющую внутреннюю поверхность, обращенную к трубчатой металлической части, и наружную поверхность, обращенную к внутренней поверхности ствола скважины, причем каждый конец разжимной металлической муфты соединен с трубчатой металлической частью, и кольцевое пространство между внутренней поверхностью разжимной металлической муфты и трубчатой металлической частью, причем разжимная металлическая муфта выполнена с возможностью разжимания; разжимают разжимные металлические муфты затрубных барьеров так, чтобы разжимные металлические муфты упирались во внутреннюю поверхность ствола скважины; устанавливают пробку в первой концевой части эксплуатационной обсадной колонны с обеспечением уплотнения внутреннего объема эксплуатационной обсадной колонны; отсоединяют буровой противовыбросовый превентор от верхней части первой обсадной колонны; соединяют фонтанное устьевое оборудование с устьевой арматурой; отсоединяют буровую платформу от скважины; удаляют пробку и начинают добычу. Изобретение также относится к скважинной системе, полученной способом согласно настоящему изобретению.The invention relates to an offshore method for preparing a well for the production of hydrocarbon-containing fluids from a wellbore, in which a drilling platform is installed to drill at least a portion of the wellbore; drilling the first part of the wellbore; install the first casing string; connecting the drilling blowout preventer to the top of the first casing string, such as via a wellhead valve; drilling the second part of the wellbore; installing a production casing string having a first end portion closest to the top of the first casing string and a second end portion, the production casing string comprising a plurality of annular barriers, and each annulus barrier having a tubular metal portion installed as part of the production casing string, and an expandable metal sleeve surrounding the tubular metal part and having an inner surface facing the tubular metal part and an outer surface facing the inner surface of the wellbore, with each end of the expandable metal sleeve connected to the tubular metal part, and an annular space between the inner surface of the expandable metal part a sleeve and a tubular metal part, wherein the expandable metal sleeve is retractable; unclenching the expandable metal sleeves of the annular barriers so that the expandable metal sleeves abut against the inner surface of the wellbore; installing a plug in the first end portion of the production casing to seal the internal volume of the production casing; disconnecting the drilling blowout preventer from the top of the first casing string; connecting the wellhead equipment with the wellhead fittings; disconnecting the drilling platform from the well; remove the plug and start mining. The invention also relates to a downhole system obtained by the method according to the present invention.
