The organic-rich hydrocarbon source rocks in Jiyang Depression are analyzed for their main sedimentary and geochemistry characteristics and resource potentials.

A restudy on the hydrocarbon occurrence of “ enriched organic matter” : A case study of Dongying Depression;

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.
