摘　　要：孤岛油田正处于开发后期,为及时调整开发方案,必须确定剩余油分布。过套管电阻率测井技术是近年来成熟起来的一种剩余油饱和度评价方法,该技术实现了在套管内对套管外地层电阻率的测量,具有较好的探测特性和动态分析范围等优势。详细阐述了ECOS过套管电阻率测井技术的原理及其资料预处理和解释方法,并将其应用于孤岛油田的生产实践中,应用结果表明,该技术适合于孤岛油田的复杂地质条件,可以解决孤岛油田剩余油饱和度评价和油藏动态分析工作。Gudao Oilfield was at the late stage of oil development,to adjust the development scheme in time,the remaining oil distribution should be determined.The technique of through-casing resistivity logging was a matured method for evaluating remaining oil saturation,which has been developed recently.The technique was used for measuring formation resistivity both outside and inside casings,it had better detecting property and wide range of dynamic detection.The principle and data processing and interpretation methods of ECOS through-casing logging technique were expounded in detail and it was used in oil production of Gudao Oilfield.Application result indicates that the technique is suitable for the complex geologic conditions in Gudao Oilfield.It can be used for evaluating the remaining oil saturation and dynamic analysis of reservoirs.
