摘要
含油饱和度是评价砂岩油气层最主要的参数。确定含油饱和度的方法较多,确定储层原始含油饱和度的方法主要有直接法和间接法,直接法是指应用密闭取心或油基泥浆取心井获得的资料,通过实验室分析直接获得原始含油饱和度的方法;间接法是指应用测井曲线、毛管压力曲线、类比等资料间接获得原始含油饱和度。阿尔奇公式是测井定量解释饱和度的理论基础。在实验室条件下,通过作模拟地层条件下的岩电实验,取得地层的真电阻率,对深侧向视电阻率进行厚度校正,建立正确的饱和度解释模型,使岩电实验所建立的饱和度模型在探明储量中得到了广泛的应用。
Oil saturation is a main parameter to evaluate sandstone oil/gas reservoir There are many methods to confirm oil saturation The main methods to confirm original oil saturation are direct and indirect method The direct method refers to obtain the original oil saturation directly by applying data of airtight sample or oil mud sample well through the laboratory analysis The indirect method refers to obtain the original oil saturation indirectly by applying well logging curves,capillary curves and analog etc Archie equation is the theory basis of well logging quantitative interpretation Formation real resistance is obtained by simulating the formation conditions of rock electromotive experiment under the laboratory condition Laterolog Deep Resistance is corrected by thickness The Saturation Interpretative Model is built correctly Saturation Interpretative Model built by rock electromotive experiment has applied widely in Proved Reserves
