摘　　要：高含硫天然气集输管道压力高且含有大量剧毒硫化氢,一旦泄漏会造成环境污染,所以急需设置合适的泄漏检测系统,及时发现泄漏并进行泄漏点定位。文中介绍了分布式感声光纤泄漏检测系统的检测原理、系统组成和功能,针对已建高含硫集输管道的现状拟定试验方案,通过埋设模拟泄漏试验装置,进行了挖掘试验和模拟泄漏试验。试验结果表明,分布式感声光纤泄漏检测系统适用于高含硫天然气管道。The high sour natural gas gathering and transmission pipeline has high pressure and contains a large amount of highly toxic hydrogen sulfide.Once it leaks,it will cause environmental pollution.Therefore,it is urgent to set up a suitable leak detection system to find the leak in time and locate the leak point.This paper introduced the detection principle,system composition and function of the distributed acoustic fiber leakage detection system.According to the current situation of the built high-sulfur gathering and transmission pipeline,a test plan was proposed.Through the burial of the simulated leakage test device,the excavation test and the simulated leakage test were carried out.The test results show that the distributed acoustic fiber leakage detection system is fit for the high sulfur natural gas pipeline.
