| 摘 要： | 湘西北地区下志留统龙马溪组发育富含有机质页岩。通过野外露头地质剖面、钻井及有机地球化学等资料分析,认为泥页岩厚度较大,有机质类型较好、有机碳含量较高、热演化程度适中、储层物性好、埋深适宜及保存条件相对较好,满足页岩气成藏要求。根据页岩气资源潜力评价方法与有利区优选标准,选定桑植-石门复向斜一带为页岩气的有利勘探区域。

| Abstract: | The lower Silurian Longmaxi Formation in northwestern Hunan is rich in organic shale. Through analyses of field outcrop sections, drilling and geochemical data, considered that the thickness of argillutite is rather large, with better organic material types, higher organic carbon content, moderate thermal evolution degree, good reservoir physical property, appropriate buried depth and relatively good preservation conditions, thus satisfied shale gas reservoiring requirements. According to shale gas resource potential evaluation methods and favorable area selection criteria, a shale gas favorable exploration area of Sangzhi-Shimen synclinorium district has been chosen. |
