摘要
本文研究了下寺湾油田油藏含油面积、有效储层相关参数和原始含油饱和度的计算方法。用回归分析方法建立了储层孔隙度、渗透率模型;通过样品岩电试验资料拟合获取了胶结指数、饱和度指数、岩性系数,利用阿尔奇公式计算含油饱和度;根据储层岩性及含油性研究确定出有效厚度下限标准。
This paper expounds the Xiasiwan oilfield reservoir oil- bearing area and effective reservoir parameters and the calculation method of the original oil saturation. Using regression analysis method to establish the reservoir porosity and permeability model. Through sample litho- electric experiment data fitting for the cementation index, the index of saturation,lithology coefficient,archie formula is used to calculate oil saturation. According to the reservoir lithology and oil content research determine the lower limit of effective thickness standards.
