摘　　要：利用声幅 变密度测井进行固井质量的评价受到诸多因素的影响。各种影响因素对声幅 变密度测井资料的影响作用有较大的差异。根据大量测井资料分析和实验研究 ,对仪器偏心、测井时间、套管尺寸与重量、地层岩性、气侵、水泥环微间隔等因素的影响作用进行了较为深入的分析 。Cement quality evaluation based on CBL-VDL(Cement Borehole Logging and Variable Density Logging) is affected by many factors,each effect of which on CBL-VDL data is quite different. On the basis of logging data analysis and experiment study,analyzed deeply are the influencing factors including tool eccentricity,logging time,case size and weight,formation lithology,gas invasion,microcement annulus and so on. The methods to identify and correct the influencing factors have been shown in the paper.
