摘要
河道砂体内部沉积结构韵律性变化和夹层的发育导致垂向上储层形成严重的非均质性,从而控制了注入水垂向上的波及体积和剩余油的分布。根据多口取心井及检查井资料,建立了各类河道砂体非均质模型,并采用检查井水洗剖面详细描述和数值模拟方法,研究了砂层内不同夹层分布及其韵律性变化所产生的非均质模型中剩余油分布规律,为该油田高含水开发后期进行井网综合调整及其剩余油挖潜提供基础。
The rhythmly change of the depositional structure and the development of the interlayer in fluvial facies sand body lead to the form of the serious anisotropy in vertical, which control the swept volume of the injected water in vertical and the dstribution of the residual oil .The authors establish various model due to of the heterogeneity of the fluvial facies sand body according to the data of the many cored well and examined well, and study the distribution of the residual oil of the anisotropic model due to different distribution of the interlayer and the rhythmly change in sand body,by means of the detailed description for the washing section and numerical modeling
