放射性γ测井数据滤波处理效果分析
Analysis of filtering effects on radioactive logging data
摘要
Abstract
Affected by radioactive fluctuations and instrument noise,existing logging tools incorporate pre-processing filtering for radioactive logging data acquisition.To effectively evaluate the erformance of current filtering methods in processing uranium logging data,this study applied and comparatively analyzed five filtering algorithms—Savitzky-Golay smoothing,moving average,convolution function,Kalman filter,and five-point cubic smoothing—in sandstone uranium logging data preprocessing.The filtering results of the uranium-bearing intervals were obtained,and the uranium grade,thickness,and per-meter uranium content were quantitatively interpreted and compared using nuclear industry uranium logging interpretation software between the original and filtered data.The differences in applying these filtering algorithms to gamma-ray logging data were elucidated,providing a basis for optimizing filtering methods in uranium gamma-ray logging and supporting the development of radioactive geophysical logging equipment.关键词
