Abstract

Изобретение относится к нефтяной промышленности, а именно к способу восстановления герметичности обсадных колонн с любой протяженностью дефектного интервала и устройству для его осуществления. Способ ремонта обсадной колонны в скважине с дефектным участком и внутренним сужением, включающий определение всей информации по дефектному интервалу, предварительное цементирование внутреннего дефектного участка по всей длине, после затвердевания цемента фрезерование дефектного участка, спуск и установку колонны-перекрывателя в зону дефекта с фиксацией сверху при помощи механических плашек, цементирование колонны-перекрывателя через разбуриваемый обратный клапан, отличается тем, что перед спуском в скважину нижний конец колонны-перекрывателя оснащают гидромеханическим толкательным оборудованием, а верхний конец - верхней герметизирующей манжетой и плашкодержателем, установленными в корпусе, при спуске которой внутри корпуса закрепляют установочное оборудование, а после спуска колонны-перекрывателя приведенное в действие созданным гидравлическим давлением гидромеханическое толкательное оборудование выталкивает механические плашки и герметизирующую манжету и прижимает их к стенке обсадной колонны, подачей нагрузки вниз колонна-перекрыватель механическими плашками заклинивается к обсадной колонне, а герметизирующая манжета герметизирует полость между колоннами, затем вращением установочного оборудования отвинчивают его от колонны-перекрывателя и, приподняв до уровня обратного клапана, производят цементирование, после чего резким перемещением установочного оборудования вниз выталкиваетсяThe invention relates to the oil industry, and in particular to a method of restoring the tightness of casing with any length of the defective interval and device for its implementation. Method for repairing a casing string in a well with a defective section and internal constriction, including determining all information on a defective interval, pre-cementing an internal defective section along its entire length, after hardening the cement, milling the defective section, lowering and installing the blocking column in the defect area with fixing from above Mechanical dies, cementing a column through a drilled check valve, is different in that before lowering into the well, the lower end of the column The opener is equipped with hydromechanical pusher equipment, and the upper end is equipped with an upper sealing collar and a die holder installed in the housing, during the descent of which the installation equipment is fixed inside the housing, and after the column is closed, the hydromechanical pusher device activated by hydraulic pressure pushes the mechanical dies and the sealing sleeve. and presses them against the wall of the casing, by applying a load down the column overlap mechanically and dies wedged to the casing, a sealing collar seals the space between the columns, and then rotating the mounting equipment is unscrewed from its Perekryvatel-column, and lifting up the check valve level, produce cementing, whereupon a sharp downward movement of the installation equipment is pushed
