摘要
设计了一维窗函数滤波因子, 并采用快速傅立叶变换(FFT) 技术对声波全波列测井波形进行了频率滤波, 获得了较纯的纵、横波和斯通利波波形。通过频率特性分析, 获得全波频率信息、能量信息, 这些信息能有效地用于地层渗透性、裂缝性及含油气性的评价。以现场实例讨论和分析了处理结果。
Filtering factor of one dimension window function is developed to filter full waveform of acoustic logs by using FFT technique, and very pure compressional, shear and Stoneley waveforms are acquired Full wave frequency, energy parameters obtained by analyzing frequency property are capable of evaluating reservoir permeability, fracture and oil gas saturation The results of processing oilfield examples are discussed
