The Analysis Of Petroleum Geological Conditions And Prediction For Favorable Areas In Yuanbaoshan Depression

This passage analysises on the logging data, seismic data, geochemical data of Yaobaoshan depression and researches them, using the theorys and methods of energy geology, oil and gas geochemistry, sedimentology and structural geology. From four aspects, including geochemical characteristics, organic matter type, organic maturity and organic matter abundance of source rock comprehensive evaluating the Yuanbaoshan deprssion and determining the hydrocarbon source rock distribution location which has certain oil and gas potentiality; the characteristics that this depression's reservoir physical property, rock body of reservoir, cover and four sets reservoir-seal assemblage are analysised and discussed in detail; analysising the trap types and reservoir forming characteristics of Yuanbaoshan depression. It comes to the conclusion that Jianwazi east anticline, Laogongyingzi west fault nose, Zhangjiawan fault nose and Mangniuyingzi anticline are oil and gas's favorable exploration areas bases on analysising the petroleum geological conditions of Yuanbaoshan depression.
