摘要
煤系气作为常规天然气重要的战略补充,是保障国家能源安全的重要资源基础。基于以往地质勘查与煤系气生产资料,探讨了焦作矿区煤系储层合层开采方式,优选出适宜的合采层段,划分了合采有利区,并通过MC-01井验证了研究方法。结果表明,矿区二1煤煤系气以煤层气和页岩气为主;最优合采产层组划分为3类和4类两种类型为宜;通过CMG软件设计了MC-01井两种压裂方案,产气效果模拟结果显示3类产层组合为该井最佳合采方案。研究成果可为焦作矿区煤系气资源开发利用提供参考。
As a significant strategic supplement to conventional natural gas,coal measure gas(CMG)is an essential resource base for ensuring national energy security.Based on the previous geological exploration and CMG production data,this paper discusses the comining methods for coal measure reservoirs in the Jiaozuo mining area,optimizes suitable co-mining intervals,delineates favorable comining zones,and validates the research method through Well MC-01.The results show that the CMG of II1 coal in the mining area is primarily composed of coalbed methane(CBM)and shale gas;the optimal classification of co-mining production layer groups is type 3 and type 4;two fracturing schemes for Well MC-01 were designed using CMG software,and the simulation results of gas production effectiveness indicate that the type 3 production layer combination is the optimal co-mining scheme for this well.The research findings can provide references for the development and utilization of CMG resources in the Jiaozuo mining area.
