江汉盆地南部二叠系烃源岩热演化特征

Thermal evolution characteristics of Permian source rocks in southern Jianghan basin.

应用含油气盆地热史及构造—热演化模拟系统 ,对江汉盆地南部不同时期剥蚀量和底部热流值进行了反演 ,恢复了二叠系烃源层埋藏史、温度史、成熟度史和油气生成史 ;探讨了二叠系烃源岩的油气热演化规律 ,阐明了不同地区油气热演化历程的差异性 ;指出燕山期。

The degradation volume and the basal heat flow value in the various periods in southern Jianghan basin are inversed using the simulation system of the geothermal history and the structural thermal evolution of hydrocarbon bearing basin; the burial history, temperature history, maturity history and hydrocarbon generation history of Permian source rocks are restored. Hydrocarbon thermal evolution rules are discussed; the difference of the hydrocarbon thermal evolution process in various areas is presented. It is pointed out that Yanshan and Himalayan Periods are the important transforming periods of the thermal evolution of organic matter of Permian source rocks.
