江苏油田真12断块E2s16储层特征及剩余油分布

真12断块E2s1^6是真武油田主力开发层系,以岩心、测井、生产动态资料为基础,通过流动单元、隔夹层、渗透率韵律类型等,研究与渗透率变化有关的储层非均质性,建立储层物性参数模型,通过油藏数模模拟两类剖面和建立不同含水期集层渗透率模型,研究油藏纵向油水运动规律,研究剩余油分布,为E2s1^6油藏最终提高采收率、改善开发效果提供依据。

RESERVOIR CHARACTERISTICS AND RESIDUAL OIL DISTRIBUTION STUDY OF E2s16 OF ZHEN 12 FAULT BLOCK IN JIANGSU OILFIELD

The E 2s 1 6 of Zhen 12 fault block is an important development system of Zhenwu oilfiled. Based on analyses of flow units, intermediate layers and rhythm types of permeability,together with data of cores,logs and production performances, the reservoir heterogeneities related to permeability variations have been studied, and the parameter models of reservoir physical characteristics have been built. By modeling two type sections with reservoir numerical simulation and building reservoir permeability models in various water bearing periods, we have studied the oil and water vertical movement rules within reservoirs and the residual oil distributions. All these will provide bases for promoting ultimate recovery and improvement of the development effect of the E 2s 1 6 reservoir.
