脉动水力压裂技术应用于煤层注水综述

fter hydraulic fracturing technology in more than 60 years of development，has not only applied in the field of oil and gas reservoirs yield by injection. Based on hard coal seam water drainage is difficult，and gas extraction inefficient status quo，introduced a kind of pulse characteristics of the hydraulic fracturing technology. Analyzed the pulse hydraulic fracturing of coal body mechanism. Coal seam water injection technology by comparing the current method， analysts believe that the role of pulsating hydraulic fracturing in coal seams have better results. Right pulse hydraulic fracturing technology in the coal seam water injection application prospect.
