摘　　要：储层饱和度测井仪（ＲＳＴ）是斯伦贝谢公司在次生伽马能谱测井仪基础上发展起来的一种新的碳氧比能谱测井仪。采用双探测器探测由中子发生器产生的高能中子以及仪器周围地层介质非弹性散射而产生的伽马能谱。可以评价地层水矿化度多变的水驱油田的剩余油饱和度及其分布；确定储层含油饱和度和井眼持油率；标定地层水电阻率。ＲＳＴ在胜利油田的应用结果表明ＲＳＴ资料比常规碳比测井资料无论在精度、垂向分辨率和测量的动态范围，还是油水界面评价和含油饱和度计算等方面都有所改进。Reservoir Saturation Tool(RST) is a new type of C/O tool, which is developed by Schlumberger on the basis of induced spectral gamma ray logging tool. RST has two detectors used for detecting high energy neutron emitted by neutron generator and inelastic scattering gamma ray emissions from formation around the tool. RST can be used to evaluate remaining oil saturation and its distribution for water flooded field with variable formation water salinity, determine for mation oil saturation and borehole oil holdup, and also calibrate formation water resistivity. Application of RST in Shengli Oilfield shows that RST is better than conventional C/O log not only in accuracy, resolution and dynamic range, but in water/oil contact evaluation and the calculation of oil saturation, etc. .
