新能源是世界能源发展趋势,煤层气是非常规天然气一种,以吸附在煤基质颗粒表面为主、部分游离于煤孔隙或溶解于煤层水中的烃类气体。研究认为三塘湖盆地水西沟群煤层发育,厚度大,分布稳定,实验测试气含量高,煤层吸附气资源丰富,1500米以浅的煤层分布面积3423km2,预测煤层气总资源量1729.4×108m3,具有相当大的勘探潜力。
New energy is the world energy development trend. CBM is a type of unconventional natural gas that is adsorbed on the surface of coal matrix particles and partially free from coal pores or dissolved in coal seam water. The study shows that the coal seams of Shuixigou Group in the Santanghu Basin are developed with large thickness and stable distribution, high gas content in experimental tests and abundant adsorbed gas in the coal seam. The coal seam distributed in an area of 1,500 meters is 3423km2 with a predicted total coalbed methane resource of 1729.4 × 108m3. Has considerable exploration potential.
