Shale petrofacies division of Wufeng-Longmaxi formations in Sichuan Basin and its periphery

Shiyou shiyan dizhi, 2020
The research of shale petrofacies is significant for the exploration of shale gas "sweet spots". Different petrographic division schemes have been proposed but no consensus has been reached. This paper has studied the criteria and boundary values of the petrographic classification reference parameters of the Upper Ordovician Wufeng-Lower Silurian ...
