Evaluation on hydrocarbon generation potentials and exploration in Jurassic Minhe Basin

Based on the comprehensive analysis of the organic carbon content, the content and conversion ratio of organic matter, parameters of pyrolysis, organic petrology parameters, biomarker characters of saturated hydrocarbon and stable carbon isotope composition of individual hydrocarbon, geochemical characters of Jurassic source rock samples in Minhe Basin and the organic matter's abundance, type and maturity are studied, and hydrocarbon generation potential are evaluated. The result shows that the source rocks are coal-measure rocks and lacustrine mud, and the organic matter which is abundant in mid-Jurassic is marine inferior creatures. Most of the organic matters are of type 2 and 3, few of them are of type 1. According to the evaluation of the petroleum geology in this basin and based on the research of belts and data quality, Wujia nose-uplift structural belt is the most favorable region;Wanquan nose structural belt is of good potential;Dazhuang structural belt is one of the favorable zone for shallow secondary reservoir. Yongdeng depression is prospective because of its big enough area, abundant resource and low exploration and research degree.
