【摘要】 油气盆地、沉积层序与油气系统的研究属于不同层次的油气资源评价的基础研究。各类原型盆地的形成与地球动力学环境有关,并可简化为裂谷盆地、前陆盆地、走滑盆地和克拉通盆地等。沉积层序驱动机制由地球动力学的不同环境所决定,沉积层序可分类为裂谷盆地层序、前陆盆地层序和走滑盆地层序。油气系统在不同地球动力学环境下形成裂谷油气系统、台地油气系统和造山油气系统。中国许多大型盆地属于大型叠合盆地,并构成复合油气系统。更多还原

【Abstract】 Hydrocarbon evaluation analysis is based on different level research, such as basin analysis, sedimentary sequence analysis, and petroleum system analysis. The forming of varied kinds of prototype basins are related to specific geodynamic scenarios, such as rift basin, foreland basin,strikeslip basin, and cratonic basin. The formings of varied kinds of sedimentary sequences are related to basin geodynamic scenarios,such as rift basin sequence, foreland basin sequence, and strikeslip basin sequence. The formings of varied kinds of petroleum systems are related to basin scenarios, so the main petroleum systems fall into three types: continental rift, platform and orogenic. Therefore, the superimposed different prototype basins have compound petroleum systems in China.更多还原
