UA55563U - Method for increase of permeability of liquid-gas reservoirs - Google Patents

Abstract

A method for increase of permeability of liquid-gas reservoirs includes opening of seam of mineral deposit with well and filling it with fluid, generation of waves with given structure on surface with following transfer of those through fluid waveguide to well with following waves turn along the seam, reflection of waves in the zone of reservoir. Waves with given structure are transferred from surface to reservoir through waveguide formed by filling pipe space with fluid, this is placed in pipe column of tightly connected tubing that is lowered into well from surface inside of drive string, or by filling with fluid of annular space, this is placed round the pipe column of tubing, and turn of wave is realized by means of packer-reflector that is attached to the bottom end of lowered pipe column of tubing at distance multiple of ¼ of wavelength, with narrowing section towards the lower end of the pipe column of tubing, and displacement of packer-reflector along the well in zone of reservoir is performed by displacement of whole pipe column of tubing that consists in the upper part of short-length elements that are multiple of ¼ of wavelength.
