METHOD FOR INCREASE OF PRODUCTIVITY OF METHANE WELLS OF COAL SEAMS

摘要

A method for increase of productivity of methane wells of coal seams is in drilling a well from day surface, its casing, coal seam uncovering, injection of working liquid with propane to coal seam under pressure enough for hydraulic fracturing of the seam. After hydraulic fracturing to the zone of treatment, through tubing, in sequence one injects a chemical system as suspension based on burning-oxidation mixture and hydroreactive composition, and by means of termite component based on alkali metals and oxides thereof one initiates combustion of the system with formation of high-temperature water vapor.
