屯留区块位于长治市西部,属沁水煤田中东翼,属于高瓦斯矿井。主采山西组(P1s)3#煤层,煤层气资源丰富,为了清除开采3#煤层瓦斯灾害,有效利用煤层气资源,本文针对该地区地层特殊、选16口井采用多种压裂方式压裂、展开压裂对比性研究,提高整个区块的压裂成功率。 Tunliu block is located in the western part of Changzhi City, is a middle-east Qinshui coalfield, belonging to the high gas mine. In the 3rd coal seam of P1s in the main mining area, the CBM resources are abundant. In order to remove the gas disasters in seam # 3 and make effective use of CBM resources, aiming at the special strata in this area, 16 fractured fractures were selected , Expand fracturing comparative study to improve the success rate of fracturing the entire block.
