ObjectivernOil and gas exploration in the Dongpu Depression of the Bohai Bay Basin has penetrated deeply buried formations, which are generally at depths more than 3500 m, mainly the Shahejie 3 Formation.However, the hydrocarbon-generation potential, model and processes for different types of kerogen in this depression have been rarely documented.Aiming at this problem, this work conducted high-temperature and high-pressure pyrolysis experiments in a closed gold tube-autoclave system on different types of kerogen.Combined with the kinetic parameters and thermal history of the Dongpu Depression,this work restored the hydrocarbon generation histories of different types of kerogen and discussed the hydrocarbon generation potential for the main source rock in the sags by basin simulation technology.The results may provide important parameters for hydrocarbon generation characteristic determination and petroleum resource reevaluation in the Dongpu Depression.
