摘要
在研究远场涡流理论的基础上,针对CNG储气井套管损伤的特点,设计研发一套远场涡流检测系统。重点阐述了激励线圈和检测线圈的功能及设计,该远场涡流检测系统可以用于CNG储气井套管损伤检测。
A Remote Field Eddy Current（RFEC） system based on RFEC theory and the features of CNG gas storage well＇s casing damage was developed. Emphasis was focused on the functions and design of driving coil and detection coil. The RFEC system can be used in CNG gas storage well＇s casing damage detection.
