摘　　要：正确、适合的标准化方法可以有效提高区块测井资料的可对比性,保障测井解释精度。通过对常用标准化方法(直方图法、曲线重叠法、骨架值法、深度趋势法、趋势面分析法)进行分析,总结了不同方法的适用范围及优缺点,建立了基于区块特征的测井资料标准化方法优选策略,优化了测井资料标准化流程。通过国内外多个区块资料处理表明:建立的标准化流程与优选策略符合实际需求,能有效完成区块测井资料标准化,保障了测井解释精度。A proper and suitable well logging data normalization method can effectively increase the comparability of well logging data of a block and guarantee well logging interpretation.Based on the analyses of usually used well logging data normalization methods,namely,histogram method,overlap method of curves,skeleton value method,depth tendency method and trend surface analysis method,the paper summarizes the application scope,advantages and disadvantages of the methods;establishes the optimization strategy of well logging data normalization methods;and optimizes the standard procedure of normalization methods.The application of the well logging data normalization procedure and strategy in several blocks at home and abroad shows that it meets actual needs;can effectively complete well logging data normalization of a block;and ensure the logging interpretation accuracy.
