By means of whole rock thermal simulating experiment in the open system,the authors have studied the effect of different heating-rate to the hydrocarbon generation of source rock(grey-black mudstone of Trias from well Ha 2 in Tarim basin).The result of experiment indicate the hydrocarbon generation of high heating-rate is near to that of low heating-rate between 350℃~500℃,while after 500℃,the hydrocarbon generation of high heating-rate is more than that of low heating-rate.In the course of heating-rate enhancing,the secondary react ion in molecules of organic matter will increase,so the hydrocarbon generation i s higher than that of low heating-rate. The result of this experiment is in op position to that of the predecessor, because the environment and course of react ion in the open system are different from that in close system. The effect of h eating-rate to the hydrocarbon generation have relation to the system of expe riment.
Key words: Heating-rate; Open system; Thermal simulation; Hydrocarbon generation; Source rock.
