摘　　要：本文从油基泥浆取心分析饱和度体积模型出发,通过对济阳坳陷现场测定饱和度影响因素的分析,利用实际资料进行回归,建立用水基泥浆取心分析残余油饱和度和其它油藏参数来估算油藏原始含油饱和度的经验公式,并经油田实际资料验证,说明方法可行,效果较好。This paper gives out an empirical formula for the determination of the original oil saturation of an oil reservoir by contructing a volumetric model of oil and water saturation from core analysis of a core taken with oil base mud as a base, taking various factors affecting the saturation values determined, so that an empirical formula using residual oil saturation from a water base mud as a base, integrated with other reservoir parameters is established. This empirical formula is tested by actual field application and is proved to be satisfactory.
