山西沁水盆地煤层气勘探方向和开发建议

Exploration Orientation and Development Proposal of Coalbed Methane in Qinshui Basin of Shanxi Province

通过研究近几年沁水盆地煤层气的资源、地质、储层成果,剖析山西组3号煤层和太原组15号煤层性质差异及其根源,分析煤层气勘探开发生产状况,进一步论述了当前沁水盆地煤层气勘探开发所存在的问题,认为沁水盆地是我国煤层气勘探开发投入工程量最多、研究程度最高、产量最大的盆地。提出沁水盆地已经具备作为整装特大型天然气田开发的条件,应该集中力量加快3号煤层煤层气勘探力度,积极研发15号煤层煤层气开发技术,争取到"十二五"末,煤层气探明储量达到8000亿m3,建成年产量50亿m3煤层气生产基地。

The authors think that Qinshui Basin is the cradle of China＇ s CBM exploration and development and is also the largest CBM production basin in China, where we conducted more research and made more engineering work of exploration and development, after studying CBM resources, geological conditions, reservoir achievements in Qinshui Basin in the recent years and analyzing the differences and source between coal seam 3 of Shanxi formation and coal seam 15 of Taiyuan formation and the condition of CBM exploration, development and production. We should focus on accelerating and intensifying the exploration of coal seam 3, improving the proportion of CBM proven reserves and actively making research and development on CBM development technology, and finally realize the development of two main coal seams in the same pace. It is estimated that CBM proved reserves shall reach 800 billion cubic meters and construct the CBM production base with the annual production volume of 5 billion cubic meters by the end of ＂the twelfth-five Year Plan＂.
