摘　　要：以国家科技重大专项《山西沁水盆地南部煤层气直井开发示范工程》成果为依据,以以往的地质勘查及研究成果为参考,对沁水盆地南部柿庄南区块煤层气地质特征进行分析。分析认为南部柿庄南区块构造简单,煤变质程度高、煤层厚度大、埋深适中而且分布稳定,有利于煤层气生成,煤层吸附能力较强,储层渗透率较好,煤层气保存条件好,是沁南煤层气勘探开发最有利区块之一。开发利用该区块煤层气资源,可有效改善地区能源结构、加快区域经济发展,降低后期煤炭开发风险,具有非常可观的社会及经济效益。Based on the result of state scientific and technological major project ＂CBM vertical well development demonstration project in the southern Qinshui Basin, Shanxi Province＂ and referred to the previous geological exploration and research results, the paper got the conclusion that geological structure in the Shizhuang south block, southern Qinshui Basin is simple, coal metamorphic degree is high, coal seams are thick, buried depth moderate and stably distributed, thus in favor of CBM generation. The coal seams have stronger adsorption capacity and better reservoir permeability, the CBM preservation condition is good. In terms of CBM exploration and exploitation, it is one of the most favorable blocks in the southern Qinshui Basin. According to the development and utilization of CBM resources in the block, it can effectively improve local energy structure, speed up regional economic development, reduce risk of later stage development of coal and bring considerable social and economic benefits.
