Prospect prediction for shale gas resources of the Lower Paleozoic in Sichuan Basin
Online published: 2012-08-20
Based on the theory of petroleumgeology and geochemistry, this paper analyzed the development and distribution of the black clay shale in organic matter in the Lower Cambrian Qiongzhusi Formation and the Lower Silurian Longmaxi Formation in the Lower Paleozoic in Sichuan Basin. Four indicators including shale thickness, total organic carbon, organic matter types and maturity were applied to evaluate the shale gas resources in Sichuan Basin. The result shows that Qiongzhusi Formation and Longmaxi Formation have thick mud shale depositions, high organic carbon content, favorable organic matter types and very important post mature condition. So, it is concluded that this area has abundant shale gas resources. It is also pointed out the favorable exploration zones in the study area.
