摘要：

在物理模拟实验的基础上探讨了断层输导能力与储层非均质性对油沿断层垂向运移和侧向分流的控制机理与模式。研究结果表明，断层输导能力与储层非均质性对油运移的控制本质上表现为“物性”（断层与储层渗透率比值）与“动力”对油垂向运移和侧向分流的耦合控制作用。两者对油的运移和纵向分布的耦合控制作用可概括为强输导能力断层-反韵律储层控运、弱输导能力断层-反韵律储层控运和强输导能力断层-正韵律储层控运3种模式。第一种模式中，油沿断层垂向运移的过程中不易侧向分流，油主要富集在直接位于区域性盖层之下的储层中；第二种模式中，油沿断层垂向运移的过程中较易侧向分流，油在纵向上各储层中均有一定的富集；第三种模式中，油沿断层垂向运移的过程中极易侧向分流，油大多富集在下部物性最好的储层中。

Abstract:

Based on physical simulation experiments, the impacts of conduction capacity of faults and reservoir heterogeneity on the mechanism and patterns of the vertical migration and lateral diversion of oil along faults are researched. The results reveal that the control of conduction capacity of faults and reservoir heterogeneity to oil migration essentially is the coupling control of physical properties (ratios of faults permeability to reservoirs permeability) and charging forces to the vertical migration and lateral diversion of oil. Three patterns, which are controlled by fault with high conduction capacity and reservoirs of inverted rhythm, fault with low conduction capacity and reservoirs of inverted rhythm, or fault with high conduction capacity and reservoirs of positive rhythm, can summarize the coupling control of the two elements to oil migration and distribution. In the first pattern, lateral diversion can hardly occur as the oil migrates vertically along the fault, and oil mostly accumulates in the reservoir beneath the cap rock. In the second pattern, lateral diversion can occur easily as the oil migrates vertically along the fault, and every reservoir can assemble some oil. In the third pattern, lateral diversion can occur more easily as the oil migrates vertically along the fault, and oil mostly accumulates in the lower reservoir with best physical property.

Key words: oil migration, simulation experiment, conduction capacity of fault, reservoir heterogeneity, lateral diversion
