摘　　要：针对现有CNG储气井井壁因腐蚀导致泄露、爆裂等问题,提出了一套超声波自动检测系统,包括超声信号的采集、腐蚀情况分析、显示、存储和回放。系统硬件包括超声波发射/接收卡和探头定位装置,软件使用VC++2005作为平台研发,并采用Microsoft SQL Server 2000存储数据。在实验中对一段井壁进行了测量,效果较好。To detect the corrosion of CNG storage wells, we proposed a system for automatic ultrasonic test, which included collection of ultrasonic signal, analysis of corrosive data, display, storage and recognition. The hardware system included an ultrasonic transmitter and receiver card and an ultrasonic probe jig. The software was written in VC＋＋, and Microsoft SQL Server 2000 was used for database. Our experiment showed that the system could effectively detect the defects in the sidewall of CNG storage wells.
