Abstract
1. Способ глушения фонтана флюида из скважины, включающий заполнение скважины промывочной жидкостью с использованием азота, поддержание в жидкости избыточного давления, постоянного уровня и тампонирование призабойной зоны скважины, отличающийся тем, что после заполнения промывочной жидкостью ствола скважины, оснащенной колонной бурильных труб, в призабойную зону скважины закачивают жидкий азот и поднимают из скважины колонну бурильных труб, а затем контролируют процессы охлаждения призабойной зоны скважины, снижения вязкости флюида и спускают в скважину другую компоновку колонны бурильных труб, потом активируют пакер, муфту в колонне и под давлением тампонируют раствором призабойную зону скважины, удаляют из скважины колонну бурильных труб, за исключением хвостовика, оснащенного гидравлической подвеской, заколонным пакером, обратным клапаном и поддерживают в скважине давление до полного отверждения раствора. ! 2. Способ по п.1 для скважины, отличающийся тем, что в скважину, с удаленной колонной бурильных труб, спускают колонну бурильных труб, оснащенных хвостовиком с гидравлической подвеской, заколонным пакером и обратным клапаном, заполняют скважину промывочной жидкостью и поддерживают в жидкости избыточное давление и уровень, а затем в призабойную зону скважины закачивают жидкий азот. 1. A method of killing a fluid fountain from a well, comprising filling the well with flushing fluid using nitrogen, maintaining an overpressure, constant level in the fluid and plugging the bottom hole zone of the well, characterized in that after filling the wellbore with the drill pipe string into the bottom hole after flushing fluid the zone of the well is pumped with liquid nitrogen and a drill pipe string is lifted from the well, and then the processes of cooling the bottom-hole zone of the well and lowering the viscosity of the fluid are monitored another arrangement of the drill pipe string is lowered into the well, then the packer is activated, the sleeve in the string and under pressure are plugged with the solution, the bottom-hole zone of the well is removed from the well, the drill string, with the exception of a liner equipped with a hydraulic suspension, an annular packer, a check valve and supported in the well pressure until complete curing of the solution. ! 2. The method according to claim 1 for a well, characterized in that a string of drill pipes equipped with a shank with a hydraulic suspension, an annular packer and a check valve is lowered into the well, with the drill string removed, the well is filled with flushing fluid and the overpressure is maintained in the fluid and the level, and then liquid nitrogen is pumped into the bottomhole zone of the well.
