本文(Ⅰ)着重研究了中国陆相湖盆沉积物中有机质向油气演化的过程.本文(Ⅱ)阐明了现代青海湖沉积物埋藏初期及早期成岩作用过程中有机质的演化特征.其结果表明陆相有机质大量开始向石油转化的深度随不同地区、不同时代、不同类型的有机质而异.最后,运用特征有机化合物、稀有气体同位素等资料,结合构造发展史阐述我国陆相油气运移的类型、规模和途径.指出近油源短距离是陆相油气运移的基本特征.
This paper (I) focuses on the evolution of organic matter-to-hydrocarbon evolution in the sediments of the continental lacustrine sediments. The evolution of the organic matter during the early and early diagenesis of the Qinghai Lake sediments is illustrated in this article (II) The depth of a large amount of petroleum conversion begins with different regions, different ages and different types of organic matter.Finally, using the characteristics of organic compounds and rare gas isotopes, combined with the history of tectonic evolution, this paper expounds the types, It is pointed out that the short distance near oil source is the basic characteristic of continental oil and gas migration.
