| 摘 要： | 为有效支撑中国石油天然气股份有限公司煤层气业务的发展，持续开展了沁水盆地南部高煤阶煤层气富集及高产控制因素研究，总结了阶段成果和煤层气开发实践经验。结论认为：沁水盆地高煤阶煤层具有低压力、低渗透率、非均质性强的特征；煤层气开采难度大，其富集成藏主要受煤质、煤层埋深、顶底板封盖性、构造、水动力条件等的控制；地下水滞留区构造翼部是富集高产的有利区域；面积降压、合理井型是实现煤层气井高产的必要条件。该成果为规模高效开发该煤层气田打下了坚实基础。

| Abstract: | In order to support the PetroChina's CBM gas development,we have studied the main controlling factors of CBM enrichment and high deliverability in the high-rank coal beds in the southern Qinshui Basin.Thus,some phase achievements and practical field practices have been summarized herein.(1)High-rank coal beds in this study area are featured by low pressure,low permeability,and high heterogeneity.(2)There is a great difficulty in CBM gas exploitation because the CBM enrichment is mainly dominated by coal qua... |
