| Abstract: | Adopting various geochemical analysis techniques including extract data, saturated hydrocarbon chromatography, kerogen microscopic observation, vitrinite reflectance, elemental analysis, infrared spectroscopy and stable carbon isotope assay,as well as Rock-Eval pyrolysis chromatography and py- rolysis-gas chromatography analyses,etc.,the authors discuss the geochemical characteristics of the ter- rigenous organic matter in the dark mudstones of Lower Tertiary in Chaluhe Depression and tentatively inquire into the probability of generating oil and gas from it. The result shows that the Lower Tertiary exinite-richer dark mudstones below 2700-2800m are the good source rocks in Chaluhe Depression. It is prospective to explore high-wax oil,light oil,condensate and natural gas in this region. |
