Key factors of controlling the hydrocarbon expulsion of the source rock in Dongying Sag;

Relationships between dynamic conditions of effective hydrocarbon expulsion and critical abundances of organic matter in carbonate source rocks;

terogeneity analysis of compaction and hydrocarbon expulsion from source rocks in faulted basin-taking Dongying sag as an example.;

The depth of hydrocarbon expulsion threshold in Fulin subsag is 2250 - 2600m.

Occurrence of hydrocarbon expulsion threshold is discussed by means of geochemical approaches.

The characteristics of hydrocarbon generation and expulsion of the source rocks in Qaidam basin were experimentally studied by means of the hot pressure physical simulation method and the hydrocarbon expulsion threshold theory.

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.
