摘　　要：采用将侧积夹层面作为沉积单元顶面处理的方法,提出了一种新的侧积夹层建模方法。以杏树岗油田杏六区东部为例,建立了该区侧积夹层地质模型,应用虚拟示踪剂数值模拟方法研究了侧积体内油水运移规律,分析判断来水方向和来水量,定量研究了侧积体内的剩余油分布。结果表明:该方法能够准确地模拟侧积体内和侧积体之间的油水运移情况,定量判别来水方向和来水量,为高含水后期侧积体内剩余油的判别及挖潜提供理论依据。Currently,interbedded layers of lateral accretion are commonly processed by applying fault method in geologic modeling.In this paper,a new modeling method for interbedded layers of lateral accretion is proposed treating interbedded layer surface of lateral accretion as the top surface of deposit units. Taking eastern Xing 6 Block in Xingshugang Oilfield as the example,the geologic model for interbedded layers of lateral accretion is established,and numerical modeling method of virtual tracer is applied to study oil and water migration regularities in lateral accretion bodies,so as to analyze and decide direction and quantity of coming water,and quantitatively study the residual oil distribution in lateral accretion bodies. This study results indicate that such method can accurately simulate oil and water migration situation in and between lateral accretion bodies,providing theory basis for judgment and tapping the latent power of residual oil in lateral accretion bodies during later period of high water content.
