Hydrocarbon-generating characteristics of lacustrine carbonate rocks
摘要
Abstract
The study on the hydrocarbon-generating of lacustrine carbonate rocks has very important significance in exploration and theory. Meanwhile, it is very weak compared with the marine carbonate rocks and the muddy source rocks. Through the kinetics simulation experiment by using lacustrine mudstone and argillaceous dolomite, the hydrocarbon-generating process of these two different lithology limnetic source rocks are researched comparatively. Based on this experiment, the hydrocarbon-generating models of these two rocks are established, respectively. The experiment result shows that the hydrocarbon-generating peak of the lacustrine carbonate rocks is later than that of the lacustrine mudstone. The peak gas generation of the lacustrine carbonate rocks is relatively late. Moreover, the hydrocarbon-generating peak of liquid hydrocarbon from the lacustrine carbonate rocks occurs at the stage of high-temperature evolution. This indicates that late hydrocarbon generation is the characteristic of the lacustrine carbonate rocks. It is considerable that the oil threshold depths of these two source rocks are different in the lacustrine carbonate rocks petroleum basin.关键词
