【摘要】 建立了滨北地区中浅层烃源岩有机质成油、成气的化学动力学模型,结合该区的古热史,定量计算了不同时期、不同地区和不同层位源岩中有机质成油、成气转化率,结果表明,滨北地区中浅层绝大部分的源岩热演程度较低,尚处于未成熟阶段,即使是演化程度较高的中央坳陷区,也是以生油为主,成气转化率较低.这预示着,滨北中央坳陷区是最主要的油气资源贡献区,并且对油资源贡献明显,对热成因天然气资源的贡献有限.更多还原

【Abstract】 In this paper, a quantitative chemical dynamic model is presented which calculates the ratio of organic matters generating oil and gas with Binbei region’s thermal history on each stage , area, layer source rocks. The results indicate that the maturation of most source rocks are lower and even though in the central sunken area , gen- erating oil is dominant. It can be predicted that the Binbei central sunken is main contributive area of generating oil and gas, and generating more oil than gas which is generated because of pyrolysate.更多还原
