FIELD: oil and gas industry.
SUBSTANCE: method involves formation of depression pressure drop between bottom-hole zone and cavity of tubing string by pumping of fluid, pressure relief with arrangement of fluid flow from bottom-hole zone to day surface at opening of quick-acting valve of tubing string cavity, creation of periodic wave processes in bottom-hole zone of formation, repetition of stages of pressure relief and creation of negative pressure pulses. Maximum increase in pressure drop is arranged between bottom-hole zone and well zone due to packer installed at design depth in annular space; monitoring of wave processes is performed using calculation system based on readings of pressure gauges and pulse pressure sensors calibrated on the installation of impact tube type.
EFFECT: higher efficiency of wave action on well.
