где Q1 - расход жидкости разрыва, закачиваемой в заливочную колонну;
Q2 - расход жидкости, закачиваемой в заколонное пространство;
S1 - площадь проходного сечения заливочной колонны;
S2 - площадь проходного сечения заколонного пространства скважины,
при этом герметизацию заколонного пространства скважины осуществляют на устье скважины после заполнения заколонного пространства дополнительной жидкостью и прекращения ее излива во время закачки жидкости разрыва, а подачу расклинивающего агента в пласт осуществляют вместе с жидкостью разрыва.1. The method of hydraulic fracturing in wells, including lowering the filling pipe string into the hydraulic fracturing zone, sealing the annulus, pumping the fracturing fluid under pressure, fracturing the rock and supplying a proppant, characterized in that prior to pumping the fracturing fluid from the inner space of the casting string and its the annular space is displaced with the gas by the borehole fluid, after which a separation plug is placed in the casting column, and during the injection of the fracturing fluid into the fill Well additional liquid is pumped into the annulus at a flow rate Q 2 defined by the relationship:
where Q 1 is the flow rate of the fracture fluid pumped into the casting column;
Q 2 - flow rate of fluid pumped into the annulus;
S 1 - the flow area of the casting column;
S 2 - the flow area of the annular space of the well,
while sealing the annulus of the well is carried out at the wellhead after filling the annulus with additional fluid and stopping its spill during the injection of the fracturing fluid, and the proppant is supplied to the formation together with the fracturing fluid.
