Abstract Early leak detection of liquid and gas of both buried and unburied pipelines remain a critical task for economical and safety reasons. Several techniques were recently suggested and tested in real-life conditions and the corresponding results are very encouraging since they offer low cost solution while they yield both true detection and accurate localization of the leak. However, most of the techniques are not robust enough for all possible scenarios and may fail under certain environmental conditions. This review paper presents the most recent findings in acoustic and infrared (IR)-based leak detection techniques which remain the most widely used techniques for liquid and gas leaks detections respectively. However, they may fail under some situations. For instance IR-based techniques are not adequate during rainy, humid, or sandy weather or when ppb sensitivity is required, while acoustic sensors are not adequate for gas leak detection or when additional sources of acoustic noise are in the vicinity of the target area. Thus, the paper provides other alternative techniques such as ground penetrating radar (GPR), temperature profiling, and photoacoustic sensing techniques. Several important research works and real-life applications are cited in an attempt to provide a reasonable cross-section of various techniques. The paper can be useful for either a fresh researcher in the area, or for a skilled R&D engineer involved in the design of a leak detection solution since it presents the most recent leak detection techniques.

油气田泄漏检测系统:现状与未来展望

摘要 出于经济和安全原因,埋地和非埋地管道的液体和气体的早期泄漏检测仍然是一项关键任务。最近提出了几种技术并在现实条件下进行了测试,相应的结果非常令人鼓舞,因为它们提供了低成本的解决方案,同时能够实现对泄漏的真实检测和准确定位。然而,大多数技术对于所有可能的场景都不够健壮,并且在某些环境条件下可能会失败。这篇综述论文介绍了基于声学和红外 (IR) 的泄漏检测技术的最新发现,这些技术仍然是分别用于液体和气体泄漏检测的最广泛使用的技术。但是,在某些情况下它们可能会失败。例如,基于 IR 的技术在下雨、潮湿、或沙质天气或需要 ppb 灵敏度时,而声学传感器不足以检测气体泄漏或当目标区域附近有其他声学噪声源时。因此,本文提供了其他替代技术,例如探地雷达 (GPR)、温度剖面和光声传感技术。引用了几项重要的研究工作和实际应用,试图提供各种技术的合理横截面。该论文对于该领域的新研究人员或参与泄漏检测解决方案设计的熟练研发工程师都非常有用,因为它介绍了最新的泄漏检测技术。而声学传感器不足以检测气体泄漏或当目标区域附近有额外的声学噪声源时。因此,本文提供了其他替代技术,例如探地雷达 (GPR)、温度剖面和光声传感技术。引用了几项重要的研究工作和实际应用,试图提供各种技术的合理横截面。该论文对于该领域的新研究人员或参与泄漏检测解决方案设计的熟练研发工程师都非常有用,因为它介绍了最新的泄漏检测技术。而声学传感器不足以检测气体泄漏或当目标区域附近有额外的声学噪声源时。因此,本文提供了其他替代技术,例如探地雷达 (GPR)、温度剖面和光声传感技术。引用了几项重要的研究工作和实际应用,试图提供各种技术的合理横截面。该论文对于该领域的新研究人员或参与泄漏检测解决方案设计的熟练研发工程师都非常有用,因为它介绍了最新的泄漏检测技术。引用了几项重要的研究工作和实际应用,试图提供各种技术的合理横截面。该论文对于该领域的新研究人员或参与泄漏检测解决方案设计的熟练研发工程师都非常有用,因为它介绍了最新的泄漏检测技术。引用了几项重要的研究工作和实际应用,试图提供各种技术的合理横截面。该论文对于该领域的新研究人员或参与泄漏检测解决方案设计的熟练研发工程师都非常有用,因为它介绍了最新的泄漏检测技术。
