摘　　要：针对葡萄花油层的地质特征及测井资料特点,提出利用窗口Fourier变换将测井信号从空间域转换到频域内,并利用高分辨率测井信号独特的幅频特性,对低分辨率测井信号的幅频特性进行处理,从而达到提高测井曲线纵向分辨率的目的。对1口取心井的实际资料处理与对比,相对于实测值,高分辨率处理值更接近于岩电分析值。In view of geological features and logging data in Putaohua reservoir, by introducing the window Fourier transform, well logging signals were transformed from spatial domain to frequency domain, amplitude frequency characteristics of the low resolution logging signal were processed according to the unique amplitude frequency characteristics of high resolution logging signal, and the goal to improve the vertical resolution of logging curve was achieved. After the actual data processing and comparison of one well, compared with the measured result, treatment results was more close to core analysis value.
