摘    要:本文介绍一种应用沃尔什变换对测井曲线进行分层的技术,即对原始测井曲线作低通滤波后,根据各条曲线值变化的加权和,由计算机自动判断,确定岩层界面。这是一种方法简单、运行速度快、结果精确、使用方便的测井曲线分层的计算机技术。通过在IBM-PC微机上对测井曲线进行分层处理的实例,证实了这种方法的可行性。文中还论述了提高分层分辨率的途径。这种方法的处理程序可用于测井资料的逐层解释、岩相分析和相关对比等方面。

关 键 词:沃尔什变换  测井曲线  低通滤波  程序

Abstract:A method for blocking and zoning well logs by using the Walsh Transform is presented, which includes low-pass filtering the logs and determining the bed boundaries based on the weighted mean of the changes in values from the filtered logs. The method is simple, fast in running, accurate and easy to use. An example given in this paper demonstrates the feasibility of the method.The way of improving the zoning resolution is also discussed. The processing program can be applied to the bed-to-bed interpretation, facies analysis and correlation of log data.
Keywords:Walsh Transform  Logs  Low-pass filtering  Program
