| 摘 要： | 对核测井曲线进行付氏变换,其纵向分辨率可以从分析振幅谱斜率变化中获得。核测井仪器的纵向响应函数不仅与仪器的结构有关,而且还含有与探测介质有关的参数。在地层界面处的曲线变化中提取出测井曲线的综合纵向响应函数。结果证实核测井曲线的纵向响应函数与仪器的固有纵向响应函数不一致。核测井曲线的综合响应函数不仅取决于仪器的响应函数,而且受测量速度、采样率,地面仪器记录方式等因素的影响。

| Abstract: | Used Fourier transforming the nuclear logs,its vertical resolution can be achieved from analyzing the changes of amplitude spectrum slope.The response function of nuclear logs not only relates with the tool 's structures,but also includes some parameters relevant to measuring formations.Integrated log response function can be derived from the change rate of logs over boundary.It is demonstrated that the vertical response function of nuclear logs is inconsistent with the inherent vertical response function of the instrument.The integrated response function of nuclear logs depends not only on the response function of the instrument, but also on the logging velocity,sampling rate and recording instruments. |
