摘　　要：根据电测井曲线可以了解地层构造。为了找出含水砂层,基于人工分层的原理,利用小波变换过零点理论对电测井曲线进行计算机自动分层,将地下土层分为含水层和隔水层。介绍小波变换原理,给出用Matlab软件实现测井曲线计算机自动分层的方法。实验结果表明,用该方法研究实测井信号,结果与人工方法基本一致,证明了小波变换用于测井信号分析与处理的有效性。论文工作对合理利用地下水资源有非常重要的意义。The stratigraphic structure can be learned according to electric well logs. To find water-beating sand stratums, this paper used the theory of wavelet transform zero-crossing to do automatic stratification with computer on electric well logs based on the principle of artificial stratification and stratified the stratums into water-beating stratums and water-resisting ones. This paper introduced the principle of wavelet transform and gave the method to use Matlab to do automatic stratification with computer on electric well logs. The experimental results using the above method to study the actual well logs are close to those by using artificial method. This proves the effectiveness of using wavelet transform to analyze and process the well logs. This work has very important significance on making rational use of groundwater resources.
