According to the relationship model of porosity between thermal maturity and density for effective muddy oil source rocks from the Dongying Sag and combined with the relationship between maturity and organic carbon rate of conversion for source rocks of various types,the appraising standard of organic carbon abundance for the effective muddy oil source rocks from the Dongying Sag has been studied.

Hydrocarbon expulsion characteristics of effective source rock in Talimu Craton Basin and their significance of petroleum geology;
