摘 要：在振动叠加、沉降等条件下，天然气储气库管线应力承载情况较为复杂。基于弹性应变
原理，应变法可以实现结构应力的无损检测。设计了应力监测系统原理样机；基于前期某含硫气藏
型储气库关键工艺窗口的多点应力、振动检测数据，选取其重点位置安装金属式应变计，覆盖压缩机
出口高温管线、270 °大弯曲管线、振幅最大水平直管线、拘束度突变点位位置等，开展应力长期监测。
对长期运行、压缩机切换、地层波动等条件下管线重点位置的应力变化进行监测，发现了压缩机管线
的承载波动特征、部分（停机）管线承受的低周疲劳载荷与机组切换时的冲击受载特征。研究结果为
压缩机设计、维护、储气库安全运行提供了重要的方法和技术支撑。

Abstract: Under the conditions of vibration superposition and settlement, the stress bearing of natural gas storage pipelines
is very complicated. Based on the principle of elastic strain, the strain method can realize the nondestructive detection of structural
stress. The stress monitoring system was designed. Based on the multi-point stress and vibration detection data of the key process
window of a sulfur-bearing gas storage, a metal strain gauge was installed at the key position, long-term stress monitoring was
carried out by covering high-temperature compressor outlet pipelines, 270 ° large bending pipelines, maximum amplitude horizontal
straight pipelines, and the position of restraint abrupt change points, etc. The monitor for stress change of pipeline key position
under the conditions of long-term operation, compressor switching, formation fluctuation, etc was carried out. It was found that the
load-bearing fluctuation characteristics of compressor pipelines, the low cycle fatigue load of some (shutdown) pipelines, and the
impact load characteristics of unit switching. The research results provided important method and technical support for compressor
design, maintenance and safe operation of gas storage.
Key words: gas storage; stress monitoring; unit switching; fatigue load
