The results showed that there are three generation and expulsion styles in Sunhu: persistent subsidence style, forepart subsidence style and secondary subsidence style.

The 17 models of original and secondary hydrocarbon generation and expulsion from marine source rocks have been established.

In order to study the different hydrocarbon generating process of dispersed organic matters ( common source rocks) and organic - rich sediments ( high - quality source rocks) , hydrocarbon generation and expulsion experiments were made by source rock cores of lower and middle Es3 from Dongying Sag directly.

Using new technologies such as the thermo-pressure simulation experiment and hydrocarbon geochemistry, the hydrocarbon generation and expulsion models for various source rocks in coal-bearing environments were studied in detail on the bases of the systematic analysis and summarization of a number of geochemical and geological data.

Relation between the main accumulation stage and the process of generation and expulsion of hydrocarbon in T_3 x~3-T_3 x~4 petroleum system of Upper Triassic in the west Sichuan depression,China;

A study on hydrocarbon expulsion model considering heterogeneity of source rocks;

But for a long time, only temperature and time are considered to be the controlling factors, whereas the pressure effect of pressure on the vitrinite reflectance and hydrocarbon generation is still unclear.
