摘　　要：在利用测井资料进行油藏描述、储层表征的过程中,首先必须对测并资料进行标准化,使测井曲线在研究工区内有统一的刻度。正确的标准化处理可以提高多井资料的可对比性,使解释精度明显提高。通过对油藏研究中常用标准化方法(直方图法,均值校正法,三孔隙度交绘法,趋势面分析法,变异函数法)的探讨,总结出各方法的适用范围、优缺点等等,为以后油藏研究中测井曲线标准化方法选用提供参考。Geophysical logging data must be first normalized to guarantee a unified scale in research area during the process of reservoir description and reservoir bed charac- terization.A proper normalization may improve the cont- rastivity of multiple logging data and greatly enhance the interpretation accuracy.After a discussion on various nor- malization methods in this paper,such as histogram meth- od,mean correction method,three-porosity crossplot, trend surface analysis and variogram analysis,their appli- cation ranges,advantages and disadvantages are compared and summarized,which provides reference for method se- lection in later reservoir study.
