摘要
LXGJ-1连续管无损检测系统可用于油田现场作业及基地室内的连续管检测,包含缺陷检测装置和椭圆度检测装置两大部分。检测系统根据漏磁检测原理对连续管壁厚、局部缺陷进行有效检测;利用高精度抗干扰位移传感器对连续管直径进行有效检测;室内试验和现场应用情况表明:该系统对连续管局部缺陷和椭圆度检测精度达到了APIRP5C7的要求,整套系统各项指标性能达到国际同行业水平。该系统的成功研制与应用,填补国内该项技术的空白,促进了我国连续管技术的发展和应用。对在役连续管进行无损检测能够有效避免由于连续管失效带来的作业安全隐患,节约生产成本,为连续管使用与管理提供科学的依据,应用前景十分广阔。
LXGJ-1 coiled tubing non-destructive testing system can be used for field service at the oilfield and indoor coiled tubing testingat the oil base.It includes two main parts – defect detecting device and ovality detecting device.The testing system can effectively inspectthickness and local defects of coiled tubing according to magnetic leakage detecting principle.It uses the high-precision anti-interferencedisplacement sensor to effectively inspect diameter of coiled tubing.The results from indoor tests and field application indicated thatinspection on partial defects and ovality of coil tubing made by this system reached the API RP5 C7 requirements.All the functional indexesof the whole system reached the same level of its international counterparts.The successful development and application of this system filleda blank in this technology at home and promoted China's coiled tubing technological development and application.Non-destructive testingof coiled tubing in service can effectively avoid the hidden faults in service safety caused by failure of coiled tubing,save production costand provide scientific data for application and management of coiled tubing.The testing system has a broad prospect for application.
