摘要

管道运输作为一种有效、经济、环保的运输方式,在石油和天然气等资源的运输方面具有独特的优势,已成为国内外油气资源的主要运输手段。在管道的服役期间对管道进行监测是确保油气管道安全运输的重要环节之一。目前,监测管道是否泄漏的方案有很多,如检漏电缆法、传感光缆法、红外线法、探地雷达法等[1]。在现有检测方法中,光纤分布式传感系统因其灵敏度高、抗电磁干扰能力强、耐腐蚀性好等特点,在长距离连续传感方面具有不可替代的优势[2],从而引起了人们的广泛关注。基于不同原理的分布式光纤传感技术已经被应用于油气管道安全监测领域中,如:西安交通大学的Gao等[3]利用光时域反射仪(OTDR)对埋地油气管道进行安全监测,可以将入侵点定位在22.4 m范围内;天津大学的曲志刚等[4]研究了一种基于马赫-曾德尔(Mach-Zehnder)光纤干涉仪的新型油气管道安全分布式光纤预警系统,可以实时检测管道沿线所发生的泄漏及其他异常事件;美国阿拉斯加Beaufort海上油田利用布里渊光时域分析仪(BOTDA)设备实时监测14 km管道沿线的温度分布曲线以判断有无泄漏发生[5];德国Stajanca等[6]利用光纤分布式声波传感器(DAS)检测气体振动,实现了对压强为8个大气压的管道内气体泄漏的检测。在各种基于光纤的监测技术中,基于DAS的管道泄漏检测技术因其具有光纤沿线动态应变的分布式定量检测特性,已成为管道泄漏的安全预警领域中最具有潜力的检测方案。

Abstract

This study proposes an online monitoring technology for oil and gas pipeline leakage based on a high-fidelity fiber-optic distributed acoustic sensor (HiFi-DAS) and introduces the measurement principle and technical advantages of DAS. The DAS can successfully detect and locate the leakage in a gas pipeline in a simulated field experiment. Considering the complex field environment and strong background noise, the wavelet denoising algorithm is adopted to further improve the detection sensitivity of leakage events, and gas leakage under pressure of 0.05 MPa is accurately detected in field experiments. Experimental results show that the proposed DAS system has superior performance in the field of oil and gas pipeline safety monitoring.
