| 摘 要： | 页岩气有别于已经大量开采的常规天然气，在成藏机理和赋存特征方面都有其独特的特点，识别与评价页岩气的方法也有别于以往对常规天然气气藏的评价模式。泥页岩厚度、埋深、总有机碳含量、成熟度是其重要的判别指标。对比美国东部典型页岩气产出地区页岩气藏地质条件，湘鄂西的恩施—建始、桑植—石门地区为下寒武统、志留系页岩气勘探有利地区。

| Abstract: | Shale gas is different from the conventional natural gas that has been already exploited widely. Because of prominent characteristics in mechanism for hydrocarbon accumulation and occurrence, identification and evaluation on shale gas are different from the previous patterns for evaluation on the conventional gas accumulation, which use thickness, depth, TOC and maturity as important indicators. In comparison with the typical shale gas produced in the east of U.S., such as in the Appalachia basin, Enshi-Jianshi, Sangzhi-Shimen in the western Hunan-Hubei area in China are favorable exploration areas for the Lower Cambrian and Silurian shale gases. |
