摘　　要：乌尔禾油田K油藏属于岩性断块油藏，岩性及油水关系复杂，且测井系列多样、资料品质差，仅用含油饱和度和孔隙度等参数识别油水层难度较大。由于各断块测井信息的种类、数量和品质不一样，考虑到普遍性和实用性，从逐点计算和分层测井解释结果中提取了POR，SW，Rwa，Rti四个参数作为识别油层、油水同层、水层的特征参数，采用改进的两向量判别分析交会图法建立了工区K油藏油水层识别的标准图版。研究表明，此法对工区油水层识别的符合率较高，简便直观、值得推广应用。K reservoir of Wuerhe oilfield belongs to the lithologic fault block oil reservoir.Because its hthology and oil-water relationship are complex, the logging suites vary much and the data quality is poor,it is difficult to identify oil and water layers with only oil saturation and porosity parameters.In consideration of universality and practicability,4 parameters (POR,SW,Rwa,Rti),which will act as feature parameters in identifying off,oil-water and water-flooded zones,are extracted from the result of point-to-point calculation and layer separation logging interpretation.The improved two-vector discriminatory analysis cross-plot method is adopted to estabhsh a standard plate of K reservoir. The research shows that the coincidence rate of oil and water identification is high.It is simple,visible and worth generalizing.
