摘　　要：简单讨论了油藏饱和度仪的测量原理。首先,利用RST的非弹性俘获资料进行碳氧比解释,计算出碳氧比,由于在给定岩性和孔隙度的情况下,碳氧比和含油饱和度呈线性关系,即可求出含水和含油饱和度。然后,根据碳氧比和各相持率的关系通过反演求取持率。应用实例处理效果与油井实际生产情况基本一致。The principle of measurement by reservoir saturation tool is introduced briefly. RST non-elastic captured data are used to interpret and calculate carbon-oxygen ratio. Under the conditions of given lithology and porosity, the carbon-oxygen ratio is in linear with saturation, by which oil and water saturations are derived. The water holdup is obtained based on the carbon-oxygen ratio and relation of each water holdup. The application result is consistent with that of production.
