摘要
常规声幅-变密度测井仪器(CBL+VDL)由于受偏心等因素影响,对大斜度井和水平井固井质量评价有很大的局限性。扇区水泥胶结测井仪(SBT)基本不受偏心影响,可以精细地评价各个分区的水泥胶结情况。通过对比分析,SBT测井方法解释结论真实可靠,突破了常规声波变密度测井的局限性,具有良好的应用效果,特别是能满足水平井和大斜度井固井质量的精确评价。
Conventional acoustic ampitude-variable density logging ( CBL + VDL ) tool has significant limitations in cement evaluation of highly-deviated wells and horizontal wells due to the effect of factors such as decentration.Sector bond logging tool ( SBT ), which is not affacted by decentration,could precisely evaluate the cement bond in each partition.Through comparative analysis, it is showed that the interpretation consequence of SBT logging method is reliable and it breaks through the limitations of conventional CBL-VDL. It has favorable application effect, especially in highly-deviated wells and horizontal wells.
