以扇区水泥胶结测井仪(SBT)在固井质量实验井的测井响应为基础,分析了可能影响SBT响应的几种因素.研究结果表明,SBT对第I界面的胶结情况反映灵敏,其补偿声波衰减值主要受固井第I界面的胶结情况和环空水泥扇形缺失的影响,而井外快速地层、第I界面水泥环隙宽度、第Ⅱ界面水泥扇形缺失、套管偏心、不同密度水泥对其响应有一定的影响,基本不受水泥环厚度、双层套管的影响.

Based on the logging response of Sector Bond Tool (SBT) in the experimental well of bond quality, several factors influenced logging response of SBT were analyzed. Logging response of SBT was sensitive to bonding conditions of the I Contact Surface and SBT compensating wave attenuation was mainly influenced by bonding conditions and annular cement imperfect. Some factors including the quick stratum, the width of the crack of 1 Contact Surface, the sector cement imperfect of Ⅱ Contact Surface, casing eccentricity and the different cement densities make some differences to SBT. The cement thickness and the double casing hardly influence logging response of SBT.
