Abstract

In order to study the hydrocarbon-generating potential of Carboniferous-Permian coal shale in Jiyang Depression, geochemistry, petroleum geology and coal geology were applied to study the residual strata distribution of Carboniferous-Permian in Jiyang Depression, organic matter abundance, organic matter types and organic matter maturity of mudstone. The results show that the thickness of the Carboniferous-Permian residual strata in Jiyang Depression is generally 200-800 m, with a maximum thickness of 900 m; the organic matter abundance of coal-bearing shale is good, and it is type III kerogen, which is conducive to gas generation, and the maturity of organic matter reaches a mature-higher maturity stage; the hydrocarbon generation potential of Benxi Formation and Taiyuan Formation is better; Medium to good hydrocarbon source rocks is able to be found in every sag of Shanxi Formation hydrocarbon source rocks, but the scope is limited, and the overall evaluation is still medium. Generally speaking, the Permo-Carboniferous coal-bearing shale in Jiyang Depression has certain shale gas exploration potential.
