通过比较大庆油田现用的不同频率的ＣＢＬ／ＶＤＬ型水泥胶结测井仪测量结果及固井质量结果， 讨论了声波频率对这种仪器评价结果的影响。发现频率低时， 由于记录到的声幅值较高， 评价结果可靠。并据此认为， 若有不同频率的ＣＢＬ测井组合， 可能查明未胶结好的薄层及套管与水泥环间的间隙。同时， 分析了固井质量评价指标ＢＩ的意义及对解释结果的影响。 By comparing the cementing logging results and the cementing quality results of CBL / VDL cement cements with different frequencies currently used in Daqing Oilfield, the effects of sonic frequency on the evaluation results of this instrument are discussed. Found that the frequency is low, due to the recorded sound amplitude higher, the evaluation results reliable. Accordingly, it is believed that if CBL logging combinations with different frequencies are used, it is possible to find out the gaps between the unbonded thin layers and the casing and the cementing ring. At the same time, the significance of cementing quality evaluation index BI and its influence on interpretation results are analyzed.
