宋延杰张守谦等：测井曲线垂直分辨率的实时评价，测井技术，１９９６（２）２０，１０１～１０７。基于实际测井曲线的垂直分辨率是测井仪器的固有垂直分辨率、采样间隔、测速、井环境等变量的函数，本文提出采用ＫＥＲＦＯＲＤ和ＧＥＯＲＧＩ时序分析方法定量评价实测曲线的垂直分辨率。计算中发现，以１／２人定义为测井曲线的垂直分辨率偏高，因此先对测井的理论曲线进行谱分析，进而给出实测曲线垂直分辨率的确定方法。实践证明，这样确定测井曲线的垂直分辨率较符合实际情况。
Based on the fact that the vertical resolution of logs is the function of intrinsic vertical resolution of logging tools, sample interval, logging speed and borehole conditions, we apply time-series analysis method proposed by KERFORD and GEORGI to quantitative evaluation of log vertical resolution. By comparing the vertical resolution of computed logs with the intrinsic vertical resolution of logging tools, it is found that the vertical resolution of logs defined by half of cutoff frequency (1/2) fo is too optimistic. Thus a method to deterthene the vertical resolution of actual logs is given in the paper on the basis of spectral analysis of theoretical logs. Examples show that the log vertical resolution so determined is reason. able.
