摘要
沉积盆地是油气生成和聚集的基本地质单元,其形成和发展为板块构造演化所控制,主要表现在两个方面,一是板块从分离到汇聚的不同阶段、板块的不同位置,产生不同的原型盆地,形成了特定的构造-沉积体系,决定了其生、储、盖等基本含油气条件;二是后期叠加的原型盆地不但本身具有新的油气地质特征,还能够改变早期原型盆地的成藏条件及油气分布规律。以板块构造演化历史为时间线索,通过对现今盆地早期原型及其后期叠加改造过程的系统解剖,用动态方法将全球处于一个威尔逊旋回的现今盆地划分为12种类型。在此基础上,总结了各类盆地的基本属性及含油气条件,为科学预测各类盆地的含油气远景奠定了基础。
Sedimentary basin is a basic geological unit of oil generation and accumulation and its formation and development is mainly controlled by plate tectonic evolution, shown as follows： （1） different stages of plate evolution from divergence to convergence and plate at different positions resulted in different proto-type basins and formed specific structure-depositional systems, which determined its basic oil and gas bearing conditions, such as source rocks, reservoirs, seals, etc. ; （2） the lateral superimposed proto-type basins not only have its own characteristics of petroleum geology, but also can change the former proto-type basins＇ oil and gas accumulation condition and distribution rules. In this paper, taking plate tectonic evolution history as a time clue, the author divided basins of modern world that were in a Wilson cycle into 12 types with a dynamic method, and through the systematic anatomy of early proto-type of today＇ s basins and its lateral superimposing and transforming process. Based on it, the basic properties and oil and gas bearing conditions of various types of basins are summarized, which may lay a foundation for scientific forecast of hydrocarbon potential of various types of basins.
