近年来,随着我国能源需求的增加和资源开发的深入,油气开采的风险也随之增大。在油气开发过程中,易出现管线超压、破裂泄漏、失压、火灾等危险情况。为了及时发现意外事故的发生,确保生产安全,需要在井口设置高效的安全系统。本文主要介绍井安系统(井口地面安全控制系统)工作原理及结构,探讨了井安系统在磨溪气田的运行情况和使用方法,分析了磨溪气田目前井安系统运行维护过程中存在的主要问题,提出了解决方案。本研究为提高气井天然气的安全生产保障能力提供了经验和思路,具有一定的实用价值。In recent years, with the increase in China’s energy demand and the deepening of resource development, the risk of oil and gas exploitation has increased. In the process of oil and gas development, pipelines are prone to overpressure, rupture and leakage, loss of pressure, fire, and other dangerous situations. In order to detect accidents in time and ensure production safety, an efficient safety system is required at the wellhead. This paper mainly introduces the working principle and structure of well-safety system (wellhead surface safety control system), discusses the operation and use of well-safety system in Moxi gas field, analyses the main problems in the operation and maintenance of well-safety system in Moxi gas field, and puts forward solutions. This study provides experience and ideas to improve the safety and security of natural gas production from gas wells, which has some practical value.
