Abstract
The abundance of organic matter, the types of kerogen and its variation regularities controlled by sedimentary environment are discussed according to the analysis results of 600m continuou cores in Niu-38 Well, Dongying Depression of Shandong, three mother materials of unfixed-form components of the kerogen:1. lower aquatic alga; 2. plant epidermal organization-cuticle; 3. herb membrane are distinguished by microscopic study with transmitted light, reflected light and fluorescence and diferent kinds of indices are proposed. Thus reliable evidences are provided for the divission of kerogen types and assessment of hydrocarbon potential.
