摘　　要：未经处置的废弃卤气井极易发生卤水和天然气泄漏,造成地下水污染和天然气燃爆等事故。本文通过调研分析盐卤矿山卤气泄漏灾变机理,介绍了注水泥封井原则和工艺,开展了在线监测技术实验研究,形成了一套较为规范的废弃井封堵治理技术,为以后的盐卤矿山治理提供了参考。Abandoned wells without proper treatment are prone to brine and natural gas leakage,leading to groundwater contamination and potential natural gas explosion incidents.This paper analyzes the disaster mechanism of brine gas leakage in salt and brine mines through research and surveys,introduces the principles and technology of cement well sealing,and conducts experimental studies on online monitoring technology and forms a set of relatively standardized sealing treatment technology for abandoned wells,which provides reference for the treatment of brine mines in the future.
