| 摘 要： | 为认识中浅层油气成藏特征，在东营凹陷中浅层油气成藏地质研究基础上，利用二维模型模拟了不同断面形态的情况下，断层对中浅层石油运移和聚集的影响。研究结果表明：(1)在幕式(非稳态)充注条件下，断层面的形态对中浅层石油的运移路径和方式构成重要的影响，S形断层面最有利于断层上、下盘砂层油的充注，这时油在砂层中的运移速率较大，而凹形断层面则有利于断层下盘砂层油的充注，凸形断层面有利于断层上盘砂层油的充注；(2)越陡、弯度越少的断层面越有利于油的运移，即通常所认为的凸形断层面对油气运移起到发散作用，凹形断面起到油气运移汇集作用从模型试验中得到证实。

| Abstract: | On the basis of geological studies of hydrocarbon migration and accumulation in the middle and shallow formations in Dongying depression, this experiment models the influence of opening faults of different fault-plane shapes on petroleum migration and accumulation with a 2-D model. The results are as follows: (1) The fault-plane shape has a great influence on the moving path and pattern of petroleum in middle and shallow formations in impulsive (unsteady) injection conditions. S-shaped faults are most favorable for the petroleum infection of both upper and lower plate layers, and the oil-moving speed is fast. Concave faults are favorable for the infection of lower sand beds, and convex faults are favorable for the infection of upper sand beds, (2) The more abrupt and less bended the faults are, the easier the migration of oil is; that is to say, convex faults play the role of divergence, while concave faults play the role of convergence, which is well known, but has not been shown by a modeling experiment. |
