| 摘 要： | 在沾化凹陷馆藏组油气成藏地质研究基础上，利用二维模型模拟了断层开启条件下，断层对馆陶组石油运移和聚集的影响。研究结果表明：（1）断层带的流体运动方式和运动相态对馆陶组石油的运移路径和方式构成重要的影响。连续（稳态）充注条件下，油首先充注断层带，然后在馆陶组上段顶部侧向运移，最后一部分油沿馆陶组下段砂层的顶部侧向运移。但幕式（非稳态）充注条件下，油首先充注断层下部和馆陶组下段→充注断层上部，并在馆陶组下段侧向运移→充注馆陶组上段，并在其中侧向运移。另外油／水两相充注时，由于水动力的作用，导致油和水的运移出现分异现象；（2）连续（稳态）充注条件下，油的侧向运移发生在隔层上部（馆陶组上段）砂层，而幕式（非稳态）充注条件下，馆陶组上、下段均发生了侧向运移，其中单一油相充注时，下部砂层油的侧向运移量大于上部砂层，而油／水两相充注时，上部砂层侧向运移量稍大于下部砂层；（3）连续（稳态）充注时有利于馆陶组上段砂层的聚集，而幕式（非稳态）充注时则有利于馆陶组下段砂层油的聚集。另外由于水动力作用的影响，油水两相充注时，有利于馆陶组上段油的聚集。

| Abstract: | On the basis of the geological study of hydrocarbon migrating and accumulating into reservoir in Guantao Fm., Zhanhua depression, this experiment models the influence of opening fault on petroleum migration and accumulation in the formation with a 2-D model. The results are as follows: (1) The moving pattern and phase of fluids in fault zone have great influence on moving path and pattern of petroleum in Guantao Fm.. When continuously injected, petroleum could have occupied the fault zone firstly, then moved laterally down the top of its upper formation, and finally down the top of its lower formation. However, in impulsive (unsteady) injection, petroleum occupied lower part of fault and the lower Guantao Fm., firstly, then upper part of fault, and migrates laterally in the lower Guantao Fm.. Finally, the upper Guantao Fm. moved laterally. In addition, when petroleum and water injected together, they would separate because of hydrodynamics. (2) When injected continuously (steadily), petroleum migrated laterally in sand bed above the barrier, while in impulsive (unsteady) injection, it migrated in both upper and lower Guantao Fm., in which quantity of lateral migration in lower sand bed is bigger than that in the upper sand bed when petroleum is injected only, and the quantity of lateral migration in upper sand bed is slightly bigger than that in lower sand bed when petroleum and water are injected together. (3) Continuous (steady) injection is favorable for petroleum accumulation in upper Guantao Fm., sand bed, while impulsive (unsteady) injection is favorable for petroleum accumulation in lower Guantao Fm., sand bed. In addition, petroleum is apt to accumulate in upper of Guantao Fm., when it is injected together with water because of hydrodynamics. |
