沾化凹陷烃源岩及生烃成藏系统研究进展
|
摘要
前人对沾化凹陷烃源岩做了大量的研究,主要集中于烃源岩的地球化学特征、原油地球化学特征、油源对比、多元供烃成藏特征、烃源岩与油气藏的关系等方面。认为沾化凹陷主力烃源岩主要为沙四上段、沙三段、沙一段三套烃源岩,同时将原油划分为单源型和混源型,通过油源对比发现沾化凹陷具有多洼多烃、多洼混源的特点。烃源岩在洼陷构造演化的过程中对油气的控制作用发生改变,将烃源岩与构造相结合构成供烃成藏单元。
Previous studies on source rocks in Zhanhua sag focused on the geochemical characteristics of source rocks, the geochemical characteristics of crude oil, the correlation of oil sources, the characteristics of hydrocarbon accumulation by multiple sources, and the relationship between source rocks and oil-gas reservoirs. It is believed that the main hydrocarbon source rocks in Zhanhua sag are mainly three sets of source rocks in the upper member of Es4,Es3 and Es1, and the crude oil is divided into single source type and mixed source type. In the process of the structural evolution of the depression, the hydrocarbon controlling action of source rocks on oil and gas was changed.
