摘要
研制声幅－变密度测井仪的目的是用于评价固井套管与水泥胶结情况及水泥与地层的胶结情况，识别快地层，区分微环形空间等。该仪器具有组合程度高、结构简单、设计精巧、集成度高等优点。文章着重介绍了仪器的设计思想、特点及应用效果。
In order to eveluate the bond quality between casing and cement, as well as that between cement and formation, acoustic amplitude-variable density logging tool is developed. It has the advantages of high combination, simple construction, elaborate design and high integration. The design features and the application effect are introduced in this paper.
