石油二次运移是一个复杂的地质过程，本文通过利用饱和地层水的低孔低渗储层砂岩来进行石油二次运移模拟实验，初步研究了此过程的变化特征。
This paper primarily discusses the changeable features of the process through the modelling experiment of secondary migration using the reservoir sandstone with ultra-low porosity and permeability.
盆地模拟是目前石油地质勘探的一项必备技术，但该技术还不很成熟，特别是在油气的二次运移和聚集量模拟上仍很薄弱。
Basin modelling is a necessary technology for petroleum exploration at present. But it is still immature, especially in the modelling of secondary migration and accumulation amount of oil and gas.
