摘　　要：针对变径管井因长期使用引起疲劳破坏等现象,提出了一种基于直进式推进的无损检测系统的设计方案。采用三维建模软件Solidworks对所设计的零部件进行实体建模,设计了检测系统的机械机构;同时,通过Solidworks Simulation对检测系统关键零部件进行了有限元分析。验证结果表明,该检测系统在压缩天然气储气井中具有运行平稳可靠、驱动效率高、检测精度高及成本低的优点。Aiming at the fatigue damage of the tubewell with variable diameter because of long term operation, the design strategy of nondestructive detection system based on straight forward is proposed. Solid modeling is conducted by adopting 3D modeling software Solidworks and the mechanical mechanism of the detection system is designed and developed. In addition, through Solidworks Simulation, the finite element analysis for critical parts of the system is accomplished. The verification result indicates that this system operates stably and reliably in compressed natural gas （CNG） storage tubewell, and features advantages of high driving efficiency and detection accuracy, but low cost.
