摘　　要：为了分析环形声波测井、扇区水泥胶结测井以及声波成像测井仪器在套管井内测量的波形,识别套管外界面的腐蚀或串槽情况,研究了偏心声源在圆管内、外激发的二维声场,给出了不同时刻的声场分布图和不同方位角的波形图,分析了不同回管厚度和声速时环绕圆管传播的波,并给出了实验结果。In order to use the data measured by circumferential acoustic device (CAD), sector bound test (SBT) and acoustic image tool, the 2D acoustic field of pipe generated by eccentric source is studied numerically. A series of snapshots at different time instants and the waveforms at several positions are given. The results clearly exhibit all wave components and their propagation characteristics. Experimental results are given too.
