摘　　要：声幅测井是评价水泥凝固质量的常用方法,已经在油田得到了广泛应用。但声幅曲线的采集质量受到许多因素的影响,要正确评价固井质量的优劣,就需要从原始资料的采集入手,将理论与实际操作相结合,剖析其主要影响因素,来保证原始资料质量,从而提高解释精度。文章以作者多年对DDL-V和EXCELL2000G&I的操作经验,结合声幅的刻度原理,分析探讨了声幅测井的影响因素及质量控制方法,供同行参考。Amplitude Log is a common method to evaluate quality of cement bonding and has been applied in many oil fields.But the acquisition quality of log data are influenced by many factors and they will influence the evaluation effects,we need to start from the acquisition of raw data,combine theory with actual operation and analyze its main influencing factors to ensure the quality of raw data.This will improve interpretation accuracy.This paper collected the author's actual operating experiences for DDL-V and EXCELL2000G&I,combined the calibration principle of acoustic log,and analyzed the influencing factors and quality control of amplitude log,just to peer reference.
