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;

The muddy hydrocarbon source rocks are the dominant type for the Manjiaer Depression and its surrounding in this period.

Distributing charactes of effective source rock and oil & gas resource potential in inter-salt non-sandstone in the Qianjiang depression;

Combined with the data of sedimentary facies, the distribution characteristics of the effective source rocks can be obtained.

Since long ago effective source rocks have been defined as rocks that have generated and discharged hydrocarbon and the discharged hydrocarbon can form commercial hydrocarbon reservoirs.

In Kongquehe area of the Tarim Basin,the identification of the effective source rocks is carried out on the basis of the existence of the potential source rocks.

When effective source rocks and ge.

Identification of effective hydrocarbon source rocks in marine strata in the Jianghan basin,Chian;

Importance and research about effective hydrocarbon source rocks.;

Although the techniques and methods for the quantitative evaluation of hydrocarbon source rock are increasingly developed, there still some problems to be solved: (1) there are disagreements on the definition of hydrocarbon source rock, in which the difference between hydrocarbon source rock and effective hydrocarbon source rock must be distinguished; (2) in determining t.
