两淮煤田煤系天然气勘探开发研究进展

Research progress on coal measure natural gas exploration development inHuaibei and Huainan Coalfields

  • 摘要: 为进一步开发安徽两淮煤田天然气,基于近年来煤系天然气的研究成果,系统总结了两淮煤田煤系天然气主要的成藏地质条件,结合潘气-1井最新钻探成果,深入剖析了石炭-二叠系煤层气、页岩气和致密砂岩气的垂向展布特征,并进一步提出了两淮煤田煤系天然气勘探开发方向。结果表明:两淮煤田煤系天然气资源潜力大,主要层位泥页岩有机质丰度高,热演化进入成熟阶段,孔裂隙系统发育一般,垂向上发育了多套稳定沉积的煤系“三气”共生组合形式。在此基础上,指出了两淮煤田下一步工作重点应立足于多种天然气资源共探共采系统开展工作,同时建立煤炭与煤系天然气勘查开发过程中各种技术规范和标准,促进煤炭与煤系天然气协同开发。

     

    Abstract: In order to further develop the coal bed methane in Huaibei and Huainan Coalfields of Anhui Province, based on the recent research achievements of the coal measure gas, the paper systematically summarized the main formation geological condition of the coal measure gas in Huaibei and Huainan Coalfields. In combination with the new drilling exploration achievements of Panqi-1 well, the paper deeply analyzed the vertical distribution characteristics of the Permo-Carboniferous coal bed methane, shale gas and tight sandstone gas and further provided the development orientation of the coal measure gas in Huaibei and Huainan Coalfields. The results showed that the coal measure gas resources in Huaibei and Huainan Coalfields would be high in potential and the main stratum mud shale would be rich in the organic matter. The thermal evolution was in the mature stage, the development of the pore cracking system would be general and in the vertical direction, several set stable sedimentation coal measure “three gas” co-formation combined mode were developed. Based on the circumstances, the paper pointed out that the next work focus of the coalfields should be conducted on the co-exploration and co-mining system of the several gas resources. Meanwhile,each technology regulations and standards were set up during the exploration development process of the coal and coal measure gas and could promote the co-development of the coal and coal measure gas.
