| 摘 要： | 在多因素叠合法优选页岩气发育有利区的基础上，构建了涵盖地质背景、页岩生烃、储集、保存、资源和开采条件6个方面17项指标的页岩气发育有利区综合评价原始指标体系，并运用主成分分析法对湘鄂西地区下寒武统牛蹄塘组页岩气发育有利区进行了实例分析。结果表明，主要影响湘鄂西地区牛蹄塘组页岩气发育有利区分布的因子为页岩品质的优劣、资源规模的大小和保存条件的好坏，通过定量评价，综合得分排在前3位的有利区分别为中央复背斜有利区、桑植—石门复向斜南有利区和宜都—鹤峰复背斜有利区。

Application of principal component analysis in shale gas favorable areas optimization |
| |
| Abstract: | Based on the shale gas favorable areas selection of multi-factor superposition method, the original index system of shale gas favorable areas assessment was constructed, including 17 indices of 6 aspects of geological settings, shale gas generating, reservoir, preservation, resources and exploitation conditions, and the principal component analysis method was applied in assessing the shale gas favorable areas of the Lower Cambrian Niutitang Formation in western Hunan and Hubei area. The results show that there are 3 factors influencing its distribution of the shale gas favorable areas of this formation, including the quality of shale, the resources amount of shale gas and the preservation conditions. With quantitative evaluation, it is found out that the top three are the central anticlinorium, the southern Sangzhi-Shimen synclinorium and the Yidu-Hefeng anticlinorium areas. |
