摘要
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.
