Title: Hydrocarbon Source-rock Expulsion Periods of Pingdiquan Formation of Fukang Sag
Abstract: The evolution features of Permian paleogeothermal temperature field were comprehensively analyzed in combination with the important geological events since Permian,wells located in uplifts,slop areas and depressions were analyzed with the method of vitrinite reflectance as well as measured data of well temperature.Meanwhile,based on the simulation of geothermal and burial history of Permian,single well thermal evolution history,2D profile and plane thermal evolution histories of source rocks were analyzed by using 2D profile in Fukang Depression for simulating the thermal evolution histories of source rocks of section in Pingdiquan Formation.The study shows that the paleogeotemperature is higher than that of current one,it is in linear strip,hydrocarbon is generated in early Triassic of Pingdiquan Formation,the peak of hydrocarbon generation is in the early period of Jurassic system.It is not as considered by previous study that hydrocarbon generation is started at the late stage of Triassic.
