摘要
含油气盆地的构造运动学过程，受控于大地构造动力学背景。不同的构造动力学背景下，形成不同类型的原型盆地。在详细讨论中国西北地区古生代和中新生代构造动力学条件的基础上，讨论了不同构造动力学背景与含油气盆地的形成和性质。盆地构造运动学过程以其旋回性发展制约着含油气盆地的沉积、沉降和生油气凹陷中心形成和发展、迁移，制约着拗陷的沉积岩系序列，控制着生油气拗陷的连续沉降过程或不同原型盆地的垂向叠加而构成的间断多阶段沉降过程，亦控制着烃源岩生烃热演化的多阶连续生烃过程。多期构造运动，又为不同时代生烃、不同类型油气提供了运聚成藏的条件，为油气多源复合成藏提供了前提。
The tectonic kinematic process of the oil-gas bearing basins is controlled by tectonic dynamic conditions.Under the conditions of different tectonic dynamic, different prototype basins were formed. On the basis of studying tectonic dynamic condition of Palaeozoic Era in Northwest China and Mesozoic-Cenozoic Era in the Chinese continent, this paper has discussed the formation and quality of different oil-gas bearing basins.The tectonic kinematic processes of the basins are of cyclicity which controls the cyclicity of the formation and development of depositon, subsidence and oil- gas generating depression center of the basins, and restricted sedimentary sequence in depression, and also limited continuous subsidence of oil-gas bearing depression which result in the formation of multistage subsidence through vertical superimposing of different prototype basins, and multistage continuous hydrocarbon - producing process of source rocks.Multiphase tectonic activity supplies the oils and gases of different epoches and various types with condition of migration, accumulation and preservation, and it is the premise for the formation of oil - gas fields with multiple sources.
