| 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。

| Abstract: | 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 12types 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. |
