套管波首波传播时间在固井质量评价中的应用

摘要

The cementation quality evaluation is currently based on acoustic amplitude variable density logging, of which the SRT as an addi-tional curve is very effective. In this paper, the detection and theoretical calculation method of SRT is introduced, and the error analysis is done. Furthermore, the quality monitoring on acoustic amplitude variable density logging and cementing quality evaluation with auxiliary fast formation is also suggested.%目前，固井质量主要采用声幅变密度( CBL/VDL)进行评价。( CBL/VDL)测井中获得的套管波首波传播时间曲线( SRT)作为辅助曲线进行固井质量评价非常有效。文章介绍了套管波首波传播时间的检测、理论计算方法，并做了误差原因分析。利用SRT进行( CBL/VDL)测井质量监控，辅助快速地层进行固井质量评价等方面进行了阐述。
