摘要
Abstract
Addressing the problems of long gas extraction cycles and low efficiency in low-permeability coal seams,a composite enhanced permeability technology combining acid fracturing and coal seam gas injection is proposed.Through a combination of theoretical analysis and field experiments,it is found that the implementation of anti permeability measures significantly improve the gas drainage purity;after the implementation of acid fracturing and coal seam gas injection to enhance permeability measures,the gas drainage purity is significantly improved,with an average gas extraction purity of 2.8～7.4 times that before the measures are implemented.On-site experiments have shown that the combined process of"acid fracturing+coal seam gas injection"has an average increase of 440%in gas drainage purity,which is significantly more efficient than a single measure.关键词
