摘　　要：测井数据给我们提供了地下地层的岩性信息,但是在生产工作中它受到泥浆、井径和仪器等测量因素的影响,出现不同井之间同一类型的测井数据的刻度有差异的情况。因此测井曲线就需要进行归一化处理来消除这些因素的影响,只有如此才能参与地震资料的反演工作,否则会影响地震反演的结果。用实例说明了地震反演过程中测井曲线归一化的重要意义。Logging data provides us with a subterranean formation lithology information,but it would be affected by the production work of mud,caliper measurements and instrumentation factors,the scale of the same type between different well logging data could have differences.So there is a need to eliminate the influence of these factors for normalization,only so that it can participate in the work of the inversion of seismic data,otherwise it will affect the results of seismic inversion.In this paper,there are examples to illustrate the significance of logging normalization in the seismic inversion proccess.
