摘　　要：文章介绍了中原油田利用声幅变密度测井技术进行老井固井质量复查的情况,通过对原固井质量评价资料与复查资料的对比,总结了固井质量变化情况,分析了固井质量发生变化的特征,研究了各种变化产生的原因,为老井固井质量评价提供了依据。This paper introduces cement bont log-variable density log (CBL-VDL) technique to the evaluation of the cemented quality of old wells in Zhongyuan oilfield. The reviewing CBL-VDL log is compared with the original cemented quality log. The variation of the cemented quality is summed up, the characteristics and the cause of the cemented quality′s variation are analyzed and researched. This result will help evaluate the cemented quality of old wells.
