为了能够解释双探测器碳氧比能谱测井 SNP- 3仪器的资料 ,建立了资料处理系统 DCO。它用新建立的解释模型计算出含水饱和度和持水率。从斯伦贝谢公司储层饱和度测井仪 RST的四边形模型出发 ,用平面解析几何导出了解释模型。在密闭取心井中 ,用测井数据计算的地层含水饱和度准确。在有油沾污的井中 ,可以确定出沾污井段。资料处理结果说明该计算模型符合地质规律 ,已取得初步的地质效果 ,具有很好的应用前景。
In order to be able to interpret the SNP-3 data from the dual-detector C / O logging, a data processing system DCO was established. It uses the newly established interpretation model to calculate water saturation and water retention. Based on the quadrilateral model of Schlumberger reservoir saturation logging instrument RST, the interpretation model was derived by using plane analytic geometry. In a closed coring well, the formation water saturation calculated using log data is accurate. In oil-contaminated wells, well sections can be identified. Data processing results show that the calculation model conforms to the geological laws and has achieved initial geological results, which has a good prospect of application.
