摘要：针对高含水油田测井分辨率不足的实际和表外储层有效解释方法的缺失，充分利用0.2m高分辨率测井新系列独特的技术优势，准确求取薄差层地层水电阻率、含水饱和度、驱油效率等地质参数。在此基础上，通过水滤状态敏感参数的优选，成功建立起水滤状态方程和重心法相结合的水淹判别方法，既准确判断出遵循“四性关系”的储层水级别，又解决了特征参数正态性带来的矛盾，建立起表外薄差层解释新方法，填补了表外薄差层有效解释方法这一空白，形成与新测井技术相配套的水淹层解释新技术。通过4口取心井资料验证，薄差层解释符合率高达87.5%，为特高含水期油田持续稳产提供了有力技术支撑。

Abstract: In the light of the reality of lower resolution of the well logging and lack of the effective interpreting methods of the untabulated reservoirs for the high-watercut oilfield, making full use of the unique technical advanta-ges of the new series of 0. 2 m high-resolution logging, the geological parameters such as the formation water resis-tivity, water saturation, oil displaced efficiency and so on were accurately determined. On the basis of the above, by means of the optimization of the sensitive parameters of the water flooding state, the discriminating method of the flooding was successfully established by the combination of the state equation and gravity center method. The meth-od can accurately judge the flooding levels following " Four Relationships" the reservoirs and solve the contradic-tions resulted from the normality of the characteristic parameters. The established interpreting method of the thin and poor untabulated layers has filled in the gap without the effective method, and moreover developed a new interpre-ting technique compatible with the new logging technology for the watered-out reservoirs.
