Abstract

Описаны система и способ гидроразрыва пласта. Система может содержать основную трубу (100), содержащую прорезь (101) для вставки, способную вмещать в себя стопорный шар, который частично внутри ее полости, и скользящую муфту (200). Скользящая муфта может содержать первую муфту (202) с внутренней поверхностью. Внутренняя поверхность может содержать карман. Первая муфта может быть выполнена с возможностью перемещения в два положения. В первом положении карман может быть расположен на поверхности основной трубы, не содержащей прорези для вставки. Такое расположение может предотвращать выход стопорного шара (502) из полости основной трубы. Во втором положении карман может быть расположен над прорезью для вставки. Такое расположение может допускать вхождение стопорного шара в полость основной трубы для попадания в карман.The system and method of hydraulic fracturing are described. The system may include a main pipe (100) containing a slot (101) for insertion, capable of containing a locking ball, which is partially inside its cavity, and a sliding sleeve (200). The sliding sleeve may comprise a first sleeve (202) with an inner surface. The inner surface may contain a pocket. The first sleeve may be movable in two positions. In the first position, the pocket may be located on the surface of the main pipe that does not contain slots for insertion. Such an arrangement may prevent the locking ball (502) from escaping from the cavity of the main pipe. In the second position, the pocket may be located above the slot for insertion. This arrangement may allow the locking ball to enter the cavity of the main pipe to enter the pocket.
