摘 要
基于电化学阻抗谱图（EIS）中低频0.01 Hz阻抗和10 Hz相位角，开发了一套适用于现场测试的便携式阻抗测试仪。在此基础上，辅以内涂层表观特征（脱落、鼓泡等）和力学性能（附着力等），建立了一套油气田设施防腐蚀内涂层服役效果快速评价方法。通过盐雾试验、附着力测试、常规电化学测试与现场便携式阻抗测试仪测试等，开展了室内和现场内涂层的检测评价。结果表明：该内涂层服役效果评价方法具有一定的适用性和可靠性；相比于传统电化学评价检测方法，该内涂层服役效果快速评价方法检测效率显著提高。

Abstract
A portable impedance tester was developed based on low frequency 0.01 Hz impedance and 10 Hz phase angle in electrochemical impedance spectrum (EIS). On this basis, a set of fast evaluation method for service effect of anticorrosion coating on facilities in oil and gas field was established, supplemented by the apparent characteristics (peeling, bubbling, etc.) and mechanical properties (adhesion, etc.) of the internal coating. The indoor and on-site detetion and evaluation of coatings were carried out through salt spray test, adhesion test, routine electrochemistry test and field portable impedance tester test. The results showed that the evaluation method of service effect of internal coating had certain applicability and reliability. Compared with the traditional electrochemical evaluation method, the detection efficiency of the fast evaluation method for the service effect of the internal coating was significantly improved.
