Research on Immature Olls in the Jizhong Depression and Its Exploration Prospect

Abstract: Immature oils in the Zhaolanzhuang and Zhaoxian oil-fields are generated from Es4-Ek1source rocks(Ro around 0.4%)with gypsum collected form the north-middle Jingxian sag of the Jizhong depression.Characteristics of the immature oil are of high viscosity(0. 98-1.08 g/cm3)and H2S( 6.5%-15%)amount of soluble organic matter is more than 0.2%,the ratio of soluble organic matter total organiccarldn is 55% It has abundant asphaltense, cyclohydrocarbons and isohydrocarbons. n-Alkanes are dom-inated by even carbon. The area has a favorable expulsion condition and bright exploration prospect.
