Abstract: Dongpu Depression is a typical salty sedimentary basin.The special sedimentary characteristics require a special method for evaluating oil and gas resources.The modeling data of the source rocks at high temperature and high pressure show that the generation window of oil and gas can be prolonged under certain temperature and pressure,which results in the increase in amount of oil and gas resource,especially in the oil supply increment.The experiments showed that the total amount of hydrocarbon generation increased,and the highest transforming rate of organic carbon reached to 41 percent under the conditions of high temperature and high pressure.The conventional method to evaluate the hydrocarbon resources of Dongpu Depression may be underestimated.The thermal simulation at high temperature and high pressure can accurately evaluate the oil and gas reserves of the source rocks in Dongpu Depression,which benefits to determination of the exploration targets.
