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 ударной волны, образующейся при периодическом открывании полости скважины на устье для вытекания скважинной жидкости, находящейся под давлением, и ее закрывании с применением вентилей, один из которых - вентиль слива жидкости соединяет полость скважины со сливной емкостью, второй - вентиль долива жидкости - с источником жидкости, находящейся под давлением, открывание и закрывание полости скважины на устье для вытекания скважинной жидкости, находящейся под давлением, осуществляют вентилем слива жидкости, периодически повышают давление в скважине соединением устья скважины с источником жидкости, находящейся под давлением, путем открытия вентиля долива жидкости, отличающийся тем, что для каждого технологического этапа обработки призабойной зоны скважины на основании геологических условий, степени кольматации, технического состояния колонны труб и технологического плана работ устанавливают скорости открывания и закрывания вентилей слива и долива жидкости, а также периодичность их повторения. A method of processing a bottom hole of a well, including pumping a liquid into the cavity of a well, forming a pressure drop between the bottom and the well cavity by creating periodic pressure pulses in the bottom in the form of a shock wave moving along the well cavity, which occurs when the hole is periodically opened at the wellhead for leakage well fluid under pressure, and closing it using valves, one of which is a fluid drain valve that connects the strips b wells with a drain tank, the second is a fluid filling valve with a source of pressurized fluid, opening and closing the well cavity at the wellhead for the flow of pressurized wellbore is carried out by a fluid drain valve, periodically increase the pressure in the well by connecting the wellhead with a source of liquid under pressure by opening a valve topping up the liquid, characterized in that for each technological stage of processing the bottom-hole zone of the well based on geologists conditions, the degree of mudding, the technical condition of the pipe string and the technological plan of work establish the speed of opening and closing the drain and topping valves, as well as the frequency of their repetition.
