【摘要】 针对贵州六盘水煤层气富集带,从向斜构造、封闭条件、煤层割理、煤的演化和含气量5个方面探讨了该地区煤层气可能富集高产的原因,认为该区大面积的向斜构造为煤层气富集高产提供了基础条件。根据各向斜煤层气赋存特征及资源状况,并考虑煤层气富集高产有利因素和经济地理条件等综合分析,提出最有利区块4个,有利区块4个。重点评述了格目底向斜和盘关向斜重点勘查目标区的最有利区块。更多还原

【Abstract】 Aiming at the rich-in coal bed methane accumulation belt in Liupanshui,Guizhou province,from the aspects of syncline structure,sealing condition,coal bed interpenetration and the evolution and gas content of the coal beds,the causes for rich and highly productive coal bed methane in this area are discussed.It is recognized that large-scaled syncline structure is the basis of coal bed methane being rich and highly productive.In view of the deposition and resources of the methane in syncline structure,considering the favorable accumulative conditions and economic geographic conditions of the methane,four most favorable areas and four favorable areas are pointed out.The target areas in Gemudi syncline and Panguan syncline are specially discussed.更多还原
