为了解江西北部瑞昌—德安地区页岩气勘探前景,以下寒武统王音铺组炭质页岩为研究对象,对王音铺组页岩的古地理条件、埋深与厚度、有机地化指标以及页岩的矿物组成成分进行研究,结合页岩气保存条件的特殊性,初步认为研究区王音铺组炭质页岩具有较好的古地理环境、厚度大、埋深适中、生气能力大、脆性矿物含量高,页岩具有自生自储自保的特征,对页岩气的保存起到重要的作用,总体来说,研究区具有较好的页岩气勘探前景。
In order to understand the prospect of shale gas in Ruichang-De’an area in northern Jiangxi Province, the following Carboniferous shale of Wangyinpu Formation in Cambrian is studied. The paleogeographic conditions, depth and thickness of Wangyipu Formation shale, According to the particularity of shale gas preservation conditions, it is preliminarily believed that the carbonaceous shale of Wangyinpu Formation in the study area has a good palaeogeographic environment with large thickness and moderate depth of burial, It is characterized by large gas-bearing capacity and high content of brittle minerals. Shale has its own characteristics of self-preservation and self-preservation, which plays an important role in the preservation of shale gas. Generally speaking, the study area has good prospect of shale gas exploration.
