针对鄂尔多斯盆地东南缘韩城煤层气区块,煤质软,渗透率低0.02~0.35 md,目前水力压裂技术对其改造有限。为了提高压裂工艺在该区域适用性,转变常规压裂思路,将压裂的主体由煤层本身转向煤层及其顶板,在研究区开展了煤储层间接压裂先导性试验研究。
For the Hancheng CBM block in the southeastern margin of Ordos Basin, coal is soft and has a low permeability of 0.02-0.35 md. At present, hydraulic fracturing technology has limited retrofitting. In order to improve the applicability of fracturing technology in this region and change the conventional fracturing mentality, the main body of fracturing is turned from the coal seam itself to the coal seam and its roof. The pilot study on indirect fracturing of coal reservoirs is carried out in the study area.
