摘　　要：玻璃钢以优越的材料特性被广泛应用于油田地面工程的油气集输、原油存储及污水处理中。由于制造工艺复杂、质量控制难度大及现场工况恶劣等因素,油田玻璃钢构件中易存在渗水、破裂、脱粘等各类缺陷,造成油气生产安全隐患。为实现对油田玻璃钢构件高效准确无损检测,设计了阵列电容成像探头,构建了具备软件锁相与通道修正功能的阵列电容成像无损检测系统,利用含人工预制缺陷玻璃钢试块对系统进行了多通道测量值的修正,并对修正后的检测系统进行了玻璃钢试块缺陷成像测试。测试结果表明阵列检测系统适配阵列电容探头且运行稳定,可实现玻璃钢构件缺陷的快速精确成像检测。At present, glass fibre reinforced polymer(GFRP) materials are widely used in oil and gas gathering and transportation, crude oil storage, and sewage treatment due to their superior material characteristics. Due to production complexity, difficulties in quality control and harsh environment, GFRP structures often contain defects(i.e. delamination, water intrusion and crack). Such defects in GFRP storage tanks and GFRP pipelines in oil fields may severely threaten the safety of oil and gas production. In this work, a capacitive imaging(CI) system with an arrayed sensor was designed to achieve efficient non-destructive evaluation(NDE) of GFRP structures used the oilfields with high accuracy. The proposed system, which includes a software based lock-in amplifier and a channel correction module, were tested using specimens with artificially prefabricated defects. The test results show that the system is compatible with arrayed capacitive probe and is promising in the efficient and high-accuracy NDE of GFRP structures.
