控制油气生成和油气藏分布的诸因素中,古构造起主导作用。构造运动对古代沉积盆地的发育、碎屑物源区及岸线在时间和空间上的位置、沉积物的数量和厚度分布特征都有重大的影响,它控制着有机物的堆积过程、地下古地温状态、烃类的生成和层内流体的运移途 Paleo-tectonics played a leading role in controlling the hydrocarbon generation and the distribution of oil and gas reservoirs. Tectonic movement has great influence on the development of ancient sedimentary basins, the location of debris source and shoreline in time and space, the quantity and thickness distribution of sediments, which controls the accumulation of organic matter, the underground paleo-earth temperature State, the generation of hydrocarbons and the passage of fluid within the layer
