Claims (4)

1. Способ создания трещины гидроразрыва в заданном интервале пласта, заключающийся в том, что в скважину спускают гидроабразивный перфоратор с насадками и шаровым клапаном, устанавливают клапанный шар, опрессовывают колонну насосно-компрессорных труб, проводят прорезание перфорационных каналов, извлекают клапанный шар, спускают в скважину пакер, производят его посадку над пластом и затем - гидроразрыв пласта, отличающийся тем, что спуск в скважину перфоратора и пакера осуществляют одновременно, при этом опрессовку колонны насосно-компрессорных труб проводят на давление гидроразрыва.1. A method of creating a hydraulic fracture in a predetermined interval of the formation, namely, that a waterjet perforator with nozzles and a ball valve is lowered into the well, a valve ball is installed, the tubing string is crimped, the perforation channels are cut, the valve ball is removed, and lowered into the well the packer, it is planted above the formation and then hydraulic fracturing, characterized in that the descent into the well of the perforator and the packer is carried out simultaneously, while the pressure testing of the pump-compressor string spring pipes are carried out on fracturing pressure. 2. Способ по п. 1, отличающийся тем, что перфоратор размещают под пакером. 2. The method according to p. 1, characterized in that the punch is placed under the packer. 3. Способ по п. 1, отличающийся тем, что перфоратор размещают над пакером, при этом пакер предварительно сажают над пластом для проведения опрессовки колонны насосно-компрессорных труб, затем срывают пакер, допускают перфоратор в заданный интервал пласта, после прорезания перфорационных каналов приподнимают пакер над пластом и повторно его сажают, в результате чего герметизируют насадки перфоратора для последующего проведения гидроразрыва пласта. 3. The method according to p. 1, characterized in that the perforator is placed above the packer, while the packer is pre-planted over the formation for crimping the tubing string, then the packer is torn off, the perforator is allowed at the specified interval of the formation, after cutting the perforation channels, the packer is lifted over the formation and re-plant it, as a result of which the perforator nozzles are sealed for subsequent hydraulic fracturing. 4. Устройство для создания трещины гидроразрыва в заданном интервале пласта, содержащее полый цилиндрический корпус с насадками и втулку, размещенную в полости корпуса, со сквозным осевым каналом, седлом под клапанный шар и уплотнениями, отличающееся тем, что втулка выполнена с хвостовиком, выступающим за пределы корпуса и соединенным с пакером, при этом корпус и втулка связаны между собой шпоночным соединением для обеспечения поворота пакера при вращении колонны насосно-компрессорных труб. 4. Device for creating a hydraulic fracture in a predetermined interval of the formation, comprising a hollow cylindrical body with nozzles and a sleeve located in the body cavity, with a through axial channel, a seat for the valve ball and seals, characterized in that the sleeve is made with a shank protruding beyond housing and connected to the packer, while the housing and the sleeve are interconnected by a key connection to ensure the rotation of the packer during rotation of the tubing string.
