| 摘 要： | 利用二维模型进行了输导层和岩性圈闭中石油运移与聚集模拟实验研究。结果表明：（１）地怪中的高渗透带是石油运移的主要通道，对油的运移和聚集构成重要的影响；（２）当上覆地层渗透性较大时，下部地层中的油可向上覆地层运移，并在运移过程中发生弥散和扩散作用，导致油的散失量增大；（３）油驱水过程中的排水过程滞后于注油过程，排出的水量并不随注油量加而线性增加，而是脉冲式变化。

| Abstract: | Simulation experiment on petroleum migration and accumulation in carrier bed and lithological trap conducted by 2_D experimental model shows the following results: (1) High permeability zone is the major pathway for petroleum migration and has an important effect on petroleum migration and accumulation; (2) When the permeability of the overlying sandy bed is high and not much less than that of the underlying sandy bed, petroleum in the underlying sandy bed migrates vertically into the overlying sandy bed. During the petroleum migration, petroleum dispersion and diffusion will occur and this causes the increase of petroleum loss; (3)The process of water discharge, when oil displaces water, is slower than the oil input, the output of water discharge does not linearly increase with the input oil, but varies pulsatingly. |
