摘　　要：八面河油田面120块位于东营凹陷南斜坡,由于差异压实作用和成岩作用的影响,储层非均质性严重。为了探索储层非均质性与油气聚集成藏的关系,指导油田下一步勘探开发,以单砂层为研究单元,应用物理模拟试验方法,探讨了储层非均质性对油气聚集的影响。结果表明储层物性非均质性对各砂层的含油性有很大的影响,渗透率级差越大,砂体含油性越差;渗透率级差越小,砂体含油性越好。Block Mian 120 in Bamianhe Oilfield was located in the southern slope of Dongying Depression. Its heterogeneity was strong because of its poor compaction and diagenesis. In order to research the relationship between reservoir heterogeneity and accumulation of oil and gas to guide the next exploration and development of the field, reservoir heterogeneity was studied and physical modeling experimentation methods were used to research the influence of heterogeneity on the accumulation of oil and gas. The result reveals that reservoir heterogeneity has a great influence on oil-bearing capacity. The higher difference of permeability is, the poorer oil-bearing capacity of sand-body is; the lower difference of permeability is, the better oil-bearing capacity of sand-body is.
