目前变密度测井技术（VDL）越来越受到各油田的重视，它不仅能反映出套管与水泥胶结的好坏，还可以表明水泥与地层的胶结情况，文中对变密度测井技术的特点，配接要点及测井过程中所出现的问题等作了分析，特别是对测井质量控制以及VDL柱状图的灰度处理等进行了分析，并根据实际的测并结果进行了验证，说明本方法是可行的。
Nowadays, density-variable logging (VDL) is getting more and more attention in all oilfields. It not only reflects the cementing of casing and cement, but also shows the cementing of cement and stratum. In this paper, Characteristics, key points of the matching and the problems occurred in the logging process. In particular, the logging quality control and the VDL histogram grayscale processing are analyzed and verified according to the actual measurement results. This method is feasible.
