摘　　要：塔河油田奥陶系储集层非均质性非常严重,裂缝、孔洞发育,油、水关系复杂,没有统一的油水界面。依据测井评价与试油资料,在统计了大量油、水层段测井参数的基础上,建立了电阻率—孔隙度交会图、自然伽马—电阻率交会图,并用纵横波比值法、正态分布法、综合流体性质判别技术等识别方法,进而建立了定量计算油、水层的识别指标。在塔河油田进行应用,识别油、水层的符合程度达到了75%以上,为塔河油田奥陶系油、水层识别、完井方案的制定,储量参数的确定提供了依据。The Ordovician reservoir in Tahe oilfield is characterized by strong heterogeneity,developed fractures and vugs,complicated oil-water relation,no uniform oil-water interface.Based on the logging evaluation and formation testing data,as well as statistical log response characteristics from lots of oil and water intervals,this paper presents the crossplots of resistivity-porosity and gamma ray-resistivity,P-S wave ratio approach,normal distribution approach and comprehensive discrimination approach to fluid property,by which proposes identification index for quantitative calculation of oil and water layers.The case study in Tahe oilfield shows that the coincidence rate for recognition of oil and water layers has reached above 75% for the purpose of making completion program and determinating reserves parameters.
