摘　　要：为分析王村夏店南区煤层气的赋存情况及开发潜力,基于研究区域内的具体地质及工程条件,采用层次分析法+模糊评价法进行研究区域内有利区的计算评价,得出勘查区3号和15号煤层的开发有利区分别为2套断层中北部和煤层中北部。进一步对煤层气勘查技术路线图和方案进行设计,并对勘查区内3口煤层气参数+排采试验井、8口生产试验井进行射孔压裂改造不同煤层,同时采用预先危险分析法对勘查施工进行安全风险评价及管控。根据目前勘查分析结果得出,3号煤层和15号煤层煤层气均具有一定开发前景。In order to analyze the occurrence and development potential of coalbed methane in the southern area of Xiadian-Wangcun, based on the specific geological and engineering conditions in the study area, the analytic hierarchy process and fuzzy evaluation method are used to calculate and evaluate the favorable areas in the study area. It is concluded that the favorable areas for the development of No.3 coal seam and No.15 coal seam in the exploration area are the north-central part of two sets of faults and the north-central part of coal seam. Further, the technical roadmap and scheme of coalbed methane exploration are designed, and 3 coalbed methane parameters + drainage test wells and 8 production test wells in the exploration area are perforated and fractured to transform different coal seams. At the same time, the pre-hazard analysis method is used to evaluate and control the safety risk of exploration and construction. According to the current exploration and analysis results, No.3 coal seam and No.15 coal seam have certain development prospects.
