- Abstract
In order to reveal the oil and gas resource potential of Upper Paleozoic coal measure source rocks in Huanghua Depression, Bohai Bay Basin, based on experiments such as rock pyrolysis, maceral identification, thermal simulation and previous research data, the geochemical characteristics, macerals and hydrocarbon generation of C-P coal seam in Dagang exploration area in Huanghua Depression are studied in detail. The results show that the macerals of C-P coal measure source rocks in Huanghua Depression are mainly vitrinite, followed by inertinite. The content of vitrinite is 60.35%, inertinite is 28.6%, and crustite + sapropel group is 11.05%. The organic matter types of the source rock are mainly type Ⅱ2 and type Ⅲ, with high abundance of organic matter. The organic matter is mainly in the mature stage. Some areas are in the high mature stage due to magmatism. Moreover, the source rock has the characteristics of gas generation and oil generation, and has good hydrocarbon generation potential.
