摘　　要：对密度测井仪器发展过程进行了简要回顾,介绍了几种提高密度测井曲线分辨率的方法,分析了这些方法的局限性。重点介绍了通过改进密度仪器探测器结构提高仪器分辨率的方法。该方法是在密度仪器远探测器附近增加一个探测器,构成双探测器,测量这两个探测器计数率比值,得到相应的密度值。A brief review on the development process of density tools is made, several methods for improving density logs resolution are introduced and the limitations of these approaches are analyzed. A method to improve the resolution of the instrument by modifying the structure of the density instrument detector is focused on. The method is to add a detector near the far detector of the density instrument, constituting a dual-detector, so as to measure the ratio of two detector counting rate and achieve the corresponding density value.
