摘要
夏克文等.测并信号GM(1,1)模型灰色滤波.测井技术,1995,19(3):172~177测井属于典型的灰色系统,测井信号可以用GM(1,1)模型灰色滤波方法处理,主要经过累加生成、构造数据矩阵B和Y、求解方程组、建立模型和逆生成处理等步骤。算例表明GM(1,1)模型灰色滤波方法简单、实用效果好,对于连续型单调变化信号可采用平滑型灰色静态滤波方法压噪,对于有数据缺失的间段型信号可采用预测型灰色动态滤波方法填补。
Geophysical well-logging is a typical grey system.Logging signals can be processed by GM(1,1)grey filtering model,the procedures of which includes accumulative generation,constructing data matrices B and Y,solving the equation group,setting up the model and reverse generation processing etc.Calculations show thatgrey filtering with GM(1,1)Model is simple,practical and effective.Grey staticsmoothing can be used for noise suppression of continuous,and monotonouslychanging signals,while prediction grey dynamic filtering can be used for discontinuous signals to add up the lost data.
