自然伽马能谱的平滑滤波处理

The disposal of gentle filter on natural gamma energy spectrum

针对自然伽马能谱在油田勘探和开发中测井数据的统计涨落 ,提出了自然伽马能谱平滑滤波处理的方法 ;根据误差理论 ,推导出自然伽马能谱平滑滤波公式 .应用该公式对比了 2组岩心样品的自然伽马能谱的平滑滤波效果 ,并进行了数学评价 .结果表明 。

In view of statistical fluctuation of measuring dat a on natural gamma energy spectrum(NGES), we put forward a new method of gentle filter on NGES. According to error theory, we deduced a formula of gentle filter on NGES, contrasted and appraised the effect of gentle filter on NGES in two se t of rock samples. This result indicates that the error with gentle filter is sm aller than the error with no gentle filter.
