METHOD TO FORM PERNEABILITY OF ROCK MASSIF AND DEVICE THEREFOR

摘要

The invention relates to mining industry and can be used for deposit development of solid, liquid and gaseous minerals and raises effectiveness of permeability formation in rock massif when treated by shock waves and prevents accidents by elimination of resonant phenomena. For this reason in the method of rock permeability improvement comprising well drilling, liquid supply to the well, bed stimulation by static pressure not exceeding a vapor one and by shock waves with their transfer through a liquid waveguide in tubing strings with further turning in the intended direction by means of aspect stabilized reflector, installation of packer to protect production string and overlaying beds from shock wave impact using hydrohammer and wave transmitter installed on a solid foundation separately from the well collar in liquid waveguide repetitive high-pressure pulses are created, strength and duration of which are determined by calculation in a way to eliminate appearance of resonant phenomena, and mode of wave action is operated based on the data on shock loads above and below the reflector constantly or intermittently received from the well face to the surface. A device is proposed to implement the claimed method.
