Способ относится к процессу скважинной гидроперфорации и может использоваться преимущественно для перфорационных обработок пласта через эксплуатационные нефтедобычные скважины. Для повышения эффективности процесса гидроперфорация включает создание отверстия в стенке обсадной колонны путем электрохимического растворения металла в месте последующего ввода в пласт зонда с соплом на конце для гидроструйного разрушения породы пласта, продвижения зонда в глубь пласта по мере образования канала. В скважину спускают на нагревательной колонне насосно - компрессионных труб выполненный из диэлектрика отклонитель, выходное отверстие которого направлено на боковую поверхность скважины. Через канал отклонителя опускается гибкий, соединенный с электрокабелем электроизолированный токопровод с токопроводящим наконечником, имеющий упор-ограничитель выдвижения токопровода. После образования отверстия в обсадной колонне через отклонитель выводится гибкий, выполненный упругим, зонд с соплом. Зонд соединен с полым штоком, перемещающимся в перфорированном контейнере через уплотнение, отделяющее верхнюю его перфорированную часть.The method relates to a process of downhole hydroperforation and can be used primarily for perforation treatments of the reservoir through production oil wells. To increase the efficiency of the process, hydroperforation involves creating a hole in the casing wall by electrochemically dissolving the metal at the point of subsequent insertion into the formation of a probe with a nozzle at the end for hydrojet fracture of the formation rock, advancing the probe deep into the formation as the channel forms. A diverter made of a dielectric, the outlet of which is directed to the lateral surface of the well, is lowered into the well on the heating string of pumping - compression pipes. Through the channel of the diverter, a flexible, electrically isolated conductor with a conductive tip, having a stop-limiter for extending the conductor, is lowered, connected to the electrical cable. After the hole in the casing has been formed, a flexible, resilient probe with a nozzle is output through the diverter. The probe is connected to a hollow rod moving in a perforated container through a seal separating its upper perforated part.
