摘　　要：针对水利工程中多参数测井地质解释中的多解性和不确定性,提出将多条测井曲线进行归一化处理,统一多参数测井数据的量纲与幅值,再对归一化后的测井曲线进行加权处理,充分利用多条测井曲线所具有的丰富信息,最后得出一个包含多种测井参数信息的综合处理分析曲线,从而有效地利用多参数测井的优势,减少或削弱部分测井曲线中的偶然误差,提高综合测井地质解释的准确度。通过在岩体风化程度划分与泥化夹层识别中的应用效果分析,证明该方法是较为行之有效的。In accordance with the multi-interpretations and uncertainty in the geological interpretation of the multi-parameters well logging, it is put forward to normalize several logging traces for integrating both the dimension and the amplitude value of the multi-parameters logging data, and then weighting the normalized logging traces for fully utilization of the rich information from all the logging traces and finally educing an analysis curve consisting of the information of the multi-logging parameters for the comprehensive processing, so as to effectively utilize the advantages of the multi-parameters well logging for decreasing or reducing part of the accidental errors of the logging traces and increasing the accuracy of the comprehensive geological interpretation of the well logging. Through analysis on the effect of the application to dividing of the weathering degrees of rock mass and distinguishing the mud inter-bed, this method is demonstrated to be more feasible and effective.
