Abstract
Изобретение относится к нефтегазодобывающей промышленности, к области бурения и эксплуатации скважин, а именно к устройствам для вторичного вскрытия и обработки продуктивных пластов. Заявляемое устройство для гидромеханической перфорации и обработки призабойной зоны пласта по варианту 1 содержит устанавливаемый в скважине и взаимодействующий с колонной насосно-компрессорных труб гидромеханический прокалывающий перфоратор, в корпусе которого установлен по меньшей мере один пробойник, выполненный с возможностью перемещения в радиальном направлении под воздействием давления рабочей жидкости, пробойник снабжен гидромониторным каналом с обратным клапаном, при этом в верхней части корпуса перфоратора установлен гидропривод, корпус которого выполнен в виде цилиндра, перфоратор и гидропривод соединены друг с другом корпусами и зафиксированы в скважине посредством пакера с якорем, а полости корпусов сообщены друг с другом, в полости цилиндра размещены взаимодействующие друг с другом плунжер с полым штоком, снабженные переточным каналом, верхняя часть цилиндра выполнена с расширением, верхняя часть полого штока выполнена с возможностью соединения с колонной насосно-компрессорных труб. В устройстве по варианту 2 в нижней части цилиндра дополнительно установлен сбивной клапан, обеспечивающий возможность проведения очистки призабойной зоны пласта. Технический результат - повышение производительности и эффективности комплексной обработки продуктового пласта, обеспечение возможности отказа от использования насосного агрегата высокого давления, снижение материальных затрат.The invention relates to the oil and gas industry, the field of drilling and operation of wells, namely, devices for the secondary opening and processing of productive formations. The inventive device for hydro-mechanical perforation and processing of the near-wellbore zone of the reservoir according to option 1 contains a hydro-mechanical piercing punch installed in the well and interacting with the tubing string and in which case at least one piercer is installed that can be moved in the radial direction under the influence of working pressure. liquids, the punch is equipped with a hydraulic channel with a check valve, while in the upper part of the punch casing there are g The drive, whose body is designed as a cylinder, the perforator and hydraulic drive are connected to each other by housings and fixed in the well by means of a packer with an anchor, and the cavities of the housings communicate with each other, a hollow stem plunger interacting with each other is placed in the cylinder cavity , the upper part of the cylinder is made with expansion, the upper part of the hollow rod is made with the possibility of connection with the tubing column. In the device for option 2 in the lower part of the cylinder there is additionally installed a whipped valve, providing the possibility of cleaning the bottomhole formation zone. The technical result is an increase in the productivity and efficiency of complex processing of the product layer, ensuring the possibility of abandoning the use of a high-pressure pumping unit, reducing material costs.
