Abstract

Изобретение относится к нефтегазодобывающей промышленности и может быть использовано при вторичном вскрытии продуктивных пластов путём формирования системы из протяженных каналов фильтрации, восстановлении нефтяных и газовых скважин и создании перфорационных отверстий в обсадной колонне. Сущность изобретения: согласно способу устанавливают на колонне лифтовых труб с возможностью поворота и осевого перемещения скважинную компоновку (СК), включающую направляющий башмак с изогнутым каналом для перемещения в нем соединительного рукава высокого давления (РВД) по меньшей мере с одной насадкой и механизм формирования отверстий (МФО) в обсадной колонне (ОК) с обеспечением совпадения направлений выходных каналов башмака и МФО и неизменности осевого расстояния между их выходными отверстиями; СК спускают на заданную глубину и устанавливают посредством трубного якоря в ОК; производят спуск геофизического прибора, определяющего пространственное положение выходных каналов СК, по показаниям которого производят поворот СК в положение, при котором выходное отверстие МФО устанавливается в заданном азимутальном направлении; после извлечения геофизического прибора на устье скважины вскрывают МФО ОК с формированием первого отверстия; производят поворот СК и устанавливают выходное отверстие МФО в следующем заданном азимутальном направлении на одном уровне без перемещения колонны лифтовых труб по стволу скважины и проведения дополнительных спускоподъемных операций; формируют следующее отверстие в ОК с контролем положения режущего инструмента; по окончании формирования отверстий в ОК без проведения спускоподъемных The invention relates to the oil and gas industry and can be used in the secondary opening of productive layers by forming a system of extended filtration channels, the restoration of oil and gas wells and the creation of perforations in the casing. Summary of the invention: according to the method, a borehole assembly (CK) is mounted on a column of elevator pipes with the possibility of rotation and axial movement, including a guide shoe with a curved channel for moving a high-pressure connection hose (RVD) in it with at least one nozzle and a hole forming mechanism MFO) in the casing (OK) ensuring the coincidence of the directions of the output channels of the shoe and the MFO and the invariance of the axial distance between their outlet openings; SC descend to a predetermined depth and set through a pipe anchor in OK; produce a geophysical instrument, which determines the spatial position of the output channels of the IC, according to the testimony of which the IC is rotated to a position in which the outlet of the MFO is installed in a given azimuth direction; after extraction of the geophysical instrument at the wellhead, the MFIs are opened to form the first hole; make the turn of the IC and install the outlet of the MFO in the next specified azimuthal direction on the same level without moving the string of lift pipes along the wellbore and conducting additional tripping operations; form the next hole in the OK with control of the position of the cutting tool; at the end of the formation of holes in the OK without conducting tripping
