摘要(Abstract)：

永顺区块位于中上扬子地台牛蹄塘组页岩气富集区,整体勘探程度较低,页岩气勘探前景不明。利用露头、岩心、测试和地震等资料,分析研究区牛蹄塘组页岩气勘探前景,以页岩气富集理论为指导,结合地球化学分析技术、地质评价—地球物理联合预测技术,评价有利勘探区块。结果表明:永顺区块牛蹄塘组具有优越的烃源供给条件,厚度大,分布广,燕山期是其主要的聚集及成藏期;页岩储层低孔低渗特征明显,储集类型多样,脆性矿物丰富,有利于页岩气储集及压裂改造;研究区构造样式相对简单,断裂、盖层发育分区性明显,关键构造事件控制源盖动态匹配。残留向斜斜坡是研究区有利的勘探目标,Ⅰ类有利区面积为102.1km~2,Ⅱ类有利区面积为88.2km~2。
