摘　　要：由于不同时期、不同系列仪器刻度等不一致,测井数据间必然存在以刻度因素为主的误差。因此,测井资料数据标准化越来越成为测井解释中一项重要的基础工作。基于同一工区,相似或相同的沉积环境、相同的层位,不同井的曲线特征应具有相似性,因此通过与邻井曲线进行对比,对一些曲线特征有较大差异的井进行标准化是比较重要的。从而为开展下一步解释处理工作做好铺垫。本文主要介绍自然伽马曲线标准化方法及其对测井解释结果的影响。There must be some errors in well logging data due to different time and inconformity of different series of tool calibration.Therefore,logging data normalization becomes more and more important in well logging interpretation.Based on the fact that log characteristics of different wells in the same work area,similar or same depositional environment and same zone have similarity,normalization of the logs which vary a lot in characteristics through comparison with the neighboring wells is very important.It will lay a solid foundation for the next interpretation process.The paper introduces a normalization method for spontaneous gamma ray logs and the effect on well logging interpretation.
