A device for increase of permeability of liquid-gas reservoirs in which tightly connected pump-compressor tube string includes tubing, to its lower end with circular gap packer-reflector is connected, at that the lower end of the tubing string has throttle opening area of cross section of which is not less that 0.1-0.3 of area of inner cross section of tightly connected pump-compressor tube string and transition from area of inner cross section of the tubing string to area of cross section of throttle opening, like transition from area of cross section of throttle opening to area of cross section of tubing string at outer side of the lower end of the tubing string is arranged by exponent. |
