摘　　要：为了探究地层水总矿化度对测井响应特征及地层流体性质的影响,应用测井理论及方法,通过对三肇凹陷徐家围子东部地区葡萄花油层地层水总矿化度与测井响应特征、地层流体性质及产量的相关性分析,探究地层水矿化度与二者的关系。研究结果表明:地层水总矿化度与自然电位曲线偏移幅度正相关、与地层电阻率呈反比、与油层产能负相关、反映流体性质,为渗透性地层识别、油水层划分提供理论依据;为低阻潜力油层的发掘指明了新的方向。In order to explore water total salinity effects on log response and formation fluid property,using logging theory and method,based on the correlation analysis of water total salinity,Log Response and formation fluid property,explore the relationship among them.The result show water total salinity correlated with migration of spontaneous potential logging positively and with formation resistivity negatively.The negative correlation was found between water total salinity and reservoir evaluation.Water total salinity could reflect the formation fluid property.Based on the analysis of water total salinity,it is progress shall be made in pervasive formation recognition,offering theory evidence for dividing water-oil layer.It points out a new direction to explore low-resistivity oil reservoir.
