In order to simulate and analyze the process of hydrocarbon generation of 4 shale samples from the Late Paleozoic Taiyuan Formation and Benxi Formation in Ordos Basin��thermal simulation experiments were made with high-pressure autoclave�� In the experimental process��methane was the major gaseous hydrocarbon product which production rate continued to increase��up to 50 mg/g when the temperature reached to 600 �森 Changes of production rate of C2�� C5showed similar characteristics in the experiments: firstly increasing to the peak value and then beginning to decrease��and thermal cracking of C2�� C5was the main source of methane production�� Gaseous hydrocarbon production rate of the samples was mainly related to the thermal maturity of organic matter�� The lower the thermal maturity was��the greater the potential of hydrocarbon generation of organic matter was��as a result��the production rate of gaseous hydrocarbon was higher in the process of thermal simulation experiments��
