Bohai Bay Basin is a hot area for research marine petroleum. Petroleum System is an important method to study petroleum. However, facing on more complicated middle-high graded petroleum exploration area, formerly elements of the Petroleum System are not enough to cover all factors. Hydrocarbon was controlled by main migration path, additionally the complicated mechanism and controlling factors in a formed oil-gas pool are carefully considered. We put “track down (oil-gas reservoir) by following clues (the main migration path of petroleum)” based on the Dongying Depression data, and drill the best of all targets for oil-gas reservoir on the condition of revealing oil resource. The venture of petroleum exploration can be reduced farthest, and the benefit of petroleum exploration can be increased farthest by the method.

Hydrocarbon Maturation

To the accurate reconstruction of the hydrocarbon generation history in the Dongying Depression, Bohai Bay Basin, East China, core samples of the Eocene Shahejie Formation from 3 shale oil boreholes were analyzed using organic petrology and organic geochemistry methods. The shales are enriched in organic matter with good to excellent hydrocarbon generation potential. The maturity indicated by measured vitrinite reflectance (%Ro) falls in the range of 0.5–0.9% and increases with burial depth in each well. Changes in biomarker and aromatic hydrocarbon isomer distributions and biomarker concentrations are also unequivocally correlated with the thermal maturity of the source rocks. Maturity/depth relationships for hopanes, steranes, and aromatic hydrocarbons, constructed from core data indicate different well locations, have different thermal regimes. A systematic variability of maturity with geographical position along the depression has been illustrated, which is a dependence on the distance to the Tanlu Fault. Higher thermal gradient at the southern side of the Dongying Depression results in the same maturity level at shallower depth compared to the northern side. The significant regional thermal regime change from south to north in the Dongying Depression may exert an important impact on the timing of hydrocarbon maturation and expulsion at different locations. Different exploration strategies should be employed accordingly.
