摘　　要：为了深化对薄互层层间干扰规律的认识,明晰非均质性对水驱油效果的影响,用恒速法对人造三维胶结物理模型进行水驱油试验,研究了层间严重非均质条件下各类储层的水驱条件及效果。实验结果表明:在合注的情况下,高渗模型在进水量、速度、动用程度都明显大于低渗模型,渗透率级差较小的两个高渗模型相互干扰,且受重力影响注入水沿底部推进明显,关闭高渗模型可有效改善低渗模型的水驱效果,因此应尽量控制渗透率级差,合理组合层系和控制压差以提高采油效果。三维物理模拟实验结果实用性强,更符合油田实际,所得规律认识对于相似油田的实际矿场生产应用具有一定的指导意义。In order to deepen the interference among the thin alternating layers of law awareness,clear heterogeneity influence on effect of water flooding,constant speed method was applied for artificial three-dimensional cementation physical model test of water flooding.Severe heterogeneity between layers is studied under the condition of all kinds of reservoir water flooding.The experimental results show that：under the condition of high permeability model,water inflow and speed were significantly greater than low permeability model,two high permeability models interfere each other if permeability is smaller,and the propulsion affected by gravity is obvious at the bottom of the injected water.It also shows closing the high permeability model can effectively improve the water flooding effect of low permeability model.Hence,we should control permeability difference,combine reasonably formation in order to improve oil recovery effect.The three-dimensional physical simulation experiments holds strong practicability,and meets well the practice of oil field.The laws obtained have certain guiding significance.
