摘要:泥质粉砂岩储层因其所含黏土矿物的附加导电性而使得含油储层电阻率明显降低，给储层含油饱和度求取带来很大的不确定性。结合苏北盆地高邮凹陷沙花瓦地区古新统阜宁组三段储层实际资料，通过大量的实验数据对Waxman-Smits模型中的阳离子当量电导值、阳离子交换浓度等关键参数进行了修正，并利用修正后建立的含油饱和度解释模型开展了精细的储层定量评价，其含油饱和度计算结果与常规阿尔奇公式相比，解释精度有了较大幅度的提高，很好地解决了该区泥质粉砂岩油层识别的难题，可为老油区精细挖潜提供借鉴。

Abstract:Due to the additional conductivity of clay minerals, oil reservoir resistivity decreases obviously in argillaceous siltstone reservoirs, which gives a great uncertainty for the calculation of oil saturation. A combination of the actual data of the 3rd member of Funing Formation in the SHW area of North Jiangsu Basin allowed some key factors of the Waxman-Smits model, such as the equivalent conductivity (B) and the exchange concentration (Qv) of cations, to be corrected with a large amount of experimental data. A detailed quantitative evaluation of reservoirs was carried out with the corrected oil saturation interpretation model. Compared with the conventional Archie formula, the accuracy of oil saturation calculation was greatly improved, which gave a good solution to the problem of the identification of argillaceous siltstone reservoirs, and provided a reference for the determination of old field potential.
