| 中文摘要: |
| 高含H2S或特高含H2S气藏越来越多投入开发利用，给油气管材带来的腐蚀问题受到极大关注。声发射（AE）是一种无损在线监测技术，具有在酸性环境下在线监测油气管材腐蚀的潜在应用。在前人研究的基础上，综述了声发射在线监测腐蚀的原理以及从声发射波形信号中能提取到的与酸性环境下油气管材腐蚀相关的计数、绝对能量（ABS）、累计能量、上升时间/幅度（RA）、平均频率（AVG frequency）以及振幅分布值b值等参数，并基于这些参数对气泡破裂、点蚀以及腐蚀裂纹产生等过程、腐蚀类型识别以及腐蚀源定位进行了综合分析。声发射在线监测技术在一定程度上能够有效识别酸性环境下油气管材腐蚀过程、类型以及定位腐蚀源，从而提高腐蚀检出能力。声发射在线监测技术对酸性环境下油气管道腐蚀防护与监测具有重要意义。 |

| More and more hydrogen sulfide or ultra-high hydrogen sulfide reservoirs are being developed and utilized, which has attracted much attention to the corrosion problems caused by oil and gas pipelines. Acoustic Emission (AE) is a non-destructive on-line monitoring technology with potential applications for online monitoring of oil and gas pipelines corrosion in acidic environment. Based on the previous studies, the principle of on-line monitoring of acoustic emission and the parameters related to corrosion of oil and gas pipelines in acidic environment, such as counting, absolute energy (ABS), accumulation energy, rise time/amplitude (RA), average frequency (AVG), and amplitude distribution value b were reviewed. Based on these parameters, the process of bubble rupture, pitting corrosion and corrosion cracking, the identification of corrosion types and the location of corrosion sources were analyzed. To a certain extent, acoustic emission on-line monitoring technology can effectively identify the corrosion process, corrosion type and location of corrosion source of oil and gas pipelines in acidic environment, so as to improve the ability of corrosion detection. Therefore, the acoustic emission on-line monitoring technology is of great significance for the corrosion protection and monitoring of oil and gas pipelines in acidic environment. |
