以贵州松河井田GP-6井为研究对象,基于分段压裂后的排采生产数据,对该区块多煤层分段压裂效果进行评价。结果表明:针对贵州松河多煤层矿区进行煤层气开发,根据地质资料、钻井资料及相关的测试分析资料,筛选合理的射孔压裂层段,利用分段压裂技术,能够有效提高煤储层的产气潜力,提高煤层气井的产气量。
Taking the GP-6 well in Songhe Minefield, Guizhou Province as the research object, the fracturing effect of multiple coal seams in this block was evaluated based on the production data of rowing after the fracturing. The results show that for coalbed methane development in the Songhe multi-seam mining area in Guizhou Province, the reasonable perforation and fracturing intervals can be selected according to the geological data, drilling data and relevant test and analysis data, and the fracturing technology can effectively increase the coal reserves Layer gas production potential and improve gas production in CBM wells.
