Abstract
Способ обработки призабойной зоны скважины, включающий закачивание в полость скважины жидкости, формирование депрессионного перепада давления между призабойной зоной и полостью скважины путем создания периодических импульсов давления в призабойной зоне в виде перемещающейся по полости скважины волны, образующейся при периодическом открывании полости скважины на устье и ее закрывании для периодического вытекания скважинной жидкости и повышении давления в полости скважины с применением вентилей, причем через вентиль слива жидкости, соединяющий устье скважины и сливную емкость, осуществляют излив жидкости из полости скважины, через вентиль долива жидкости, соединяющем устье скважины с источником жидкости, находящейся под давлением, повышают давление в полости скважины, вентили слива и долива жидкости открывают с периодичностью, обеспечивающей раскачку в скважине ее массы, отличающийся тем, что при открывании вентиля слива жидкости одновременно закрывают вентиль долива жидкости, при закрывании вентиля слива жидкости одновременно открывают вентиль долива жидкости, долив жидкости в полость скважины осуществляют насосом из сливной емкости.A method of processing a bottom hole zone of a well, including pumping liquid into a cavity of a well, forming a pressure drop between the bottom hole and a well cavity by creating periodic pressure pulses in the bottom hole in the form of a wave generated during periodic opening of the well cavity at the wellhead and closing it for periodic leakage of the borehole fluid and increasing the pressure in the cavity of the borehole using valves, moreover, through the valve drain fluid, connecting the wellhead and the drainage tank, the fluid is poured out of the well cavity, the pressure in the well cavity is increased through the fluid filling valve connecting the wellhead to the source of fluid under pressure, the drain and fluid filling valves are opened with a frequency to ensure that it is pumped in the well mass, characterized in that when opening the drain valve at the same time close the valve topping up the liquid, when closing the valve to drain the liquid at the same time open the valve topping up Doliv fluid in the well cavity is carried out from the pump discharge capacity.
