摘　　要：用声波全波列测井资料回放的变密度图及从套管波首波提取的声幅曲线对套管井进行固井质量检查取得了比较理想的效果。实际资料说明该方法较普通声幅能更准确地鉴定水泥环 2个界面胶结质量 ,而且达到定量化。到目前 ,吉林油田 10 0多口井进行了声波变密度测井 ,98%的井的试油、投产结果均与第一。Cement bonding quality of the casing wells was evaluated with variable density plot playbacked from fullwave acoustilog data and sonic amplitude curves from the first arrivals of the casing wave,the result of which is ideal.The existent data show that the method is more accurate than general sonic amplitude log in identifying the cementing quality of two interfaces and is a better quantitative method.Up to date,sonic-variable density logging has been made in more than 100 wells in Jiling Oilfield,about 98 percent of wells'oil production agree well with the evaluated two boundaries.
