摘要
核测井信号的统计特性,使原始测井数据必须经过一定的数字滤波处理才能应用。为了设计性能良好的数字滤波器,本文简述了加权平均滤波方法、中值滤波方法、以及自适应滤波方法的算法和设计方法,提出了适合核测井信号的混合滤波方案和软硬结合的数字滤波新模式,并给出了混合滤波方案的实现流程。应用实例证明了混合滤波方案的有效性。
The raw data should be used after somekind of filtering because of the statistical properties of nuclear logging signals. The algorithm and thedesigning method of the weighted coefficient filter,media value filter and adaptive filter are formulated in order to design better digital filters. The mixing filter scheme is presented for nuclear logging signals, and a new mode of filtering to use hardware and software is presented as well. The realizing flow charts of mixing filter scheme are given out. The example verifies the validation of the mixing filter scheme.
