| 摘 要： | 本文在国内首次模拟了野外露头的埋藏史和地热史,并通过人工改变埋藏轨迹,预测了盆地内中侏罗统地下烃源岩的有机质成熟度.西宁盆地现今出露的中侏罗统烃源岩的镜质体反射率为0.59%,刚进人生油门限.模拟结果表明:地下同层位、同深度烃源岩的镜质体反射率为0.82%,达到了大量生油的成熟阶段.

| Abstract: | The burial history and thermal history of the outcrop are modelled firstly in China, and the organic matter maturity (Ro% of subsurface source rock is predicted by artificial changing burial trace. The vitrinite reflectance of mid-Jurrasic source rock in Xining basin is 0. 59%, which just reaches the petroleum generating threshold. But our modelling result shows that the Ro% of same formation underground in the basin is 0. 82%, which is mature and can generate lots of petroleum. |
