Hydrocarbon source rock characteristics and exploration direction in Xingrenpu Sag, Liupanshan Basin

The Xingrenpu Sag is located in the southeast of Liupanshan Basin, which is a Mesozoic basin in the early evaluation stage with only limited exploration. The geochemical parameters of hydrocarbon source rocks such as organic matter abundance, type and maturity and the favorable factors for reservoir formation were discussed based on drilling, outcrop core, two-dimensional earthquake and magnet data. The source rocks of the Triassic Yanchang Formation in the sag are medium source rocks, the organic matter belongs to type Ⅱ-Ⅲ, and the maturity is low-mature to mature, which show a certain exploration potential. The exploration of self-generated and self-reservoired resources should be focused on in the future. The Jurassic Zhiluo Formation source rocks are good hydrocarbon source rocks with typeⅠ-Ⅱ organic matter, and the maturity is low-mature to mature, providing exploration targets for structural and lithologic traps.
