Abstract
A method is described for producing gas from fluid-containing formations, including the steps of generating elastic vibrations by a generator and stimulating a fluid-containing formation by the elastic vibrations, extracting gas from a gas trap through a well, the generating step involving the step of increasing frequency of elastic vibrations within a frequency range from 0.1 Hz to 350.0 Hz, followed by the step of reducing the frequency within the same frequency range.
Claims25
A method of producing gas from fluid-containing formations having at least one gas trap, comprising the steps of:
- generating elastic vibrations by a main generator and stimulating a fluid-containing formation with the elastic vibrations;
- extracting gas from said gas trap through a well;
- wherein said generating step comprises increasing the frequency of elastic vibrations within a frequency range from 0.1 Hz to 350.0 Hz,
- said increasing the frequency of elastic vibrations being followed by reducing the frequency thereof within said frequency range.
A method of producing gas from fluid-containing formations having at lease one gas trap, comprising the steps of:
- generating elastic vibrations by a main generator and stimulating a fluid-containing formation with the elastic vibrations;
- extracting gas from said gas trap through a well;
- wherein said generating step comprises increasing the frequency of elastic vibrations within a frequency range from 0.1 Hz to 350.0 Hz;
- said increasing the frequency of elastic vibrations being followed by reducing the frequency thereof within said frequency range;
- further drilling wells to an aquiferous fluid-containing formation or bed, having a gas trap;
- on the said wells the bed liquid is pumped to the surface to utilize the heat thereof, the cooled bed liquid being further repumped to the said fluid-containing formation, having a gas trap for artificial flooding thereof.
