摘　　要：在分析PNN测井独特的数据采集、处理技术及地层水矿化度、孔隙度、泥质含量等对测量数据影响的基础上,指出了PNN测井技术传统体积模型的局限性,提出了利用交会图法确定关键参数并综合应用各种模型准确求取地层含油气饱和度的方法。该方法很好地解决了PNN测井资料数据处理解释中的一些难题,并在海上油田实际应用中取得了较好效果。By analyzing the unique PNN techniques of data collection and processing and the influences of several factors, such as water salinity, porosity and shale content, on the limitations of conventional PNN logging data, the volume models of PNN logging are pointed out, and a method to accurately calculate hydrocarbon saturation is developed by determining the key parameters in a crossplot and using comprehensively various models. Some difficulties in data processing of PNN logging can be effectively overcome by using this method, and its application in offshore fields has resulted in quite good effects.
