Application of Staged Fracturing Technology in Guizhou Songhe Coalbed Methane Development
-
摘要: 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。Abstract: Taking GP-6 shaft in Guizhou Songhe Mine as research object, based on the drainage production data after staged fracturing, we evaluate multiple seam staged fracturing effect in this area. The results showed that selecting reasonable perforation fracturing layer and using the staged fracturing technique can effectively improve the gas production potential of the coal reservoir and improve the gas production capacity of the coalbed methane well for the coalbed methane development in multiple seam of Guizhou Songhe Mine according to the geological data, drilling data and related test analysis data. Staged fracturing technology in multiple seam of coalbed methane development has obtained good effect in Guizhou Songhe Mine.
