一、引言哈里伯顿井口安全截断系统是天然气生产井站重要的安全设备,已经成为井站的标准化配置。保证安全截断系统的功能有效并缩短其关井响应时间,对井站的安全生产具有重要意义。较好地使用井口安全截断系统,能够有效控制事故事态,减小或避免事故损失。二、井口安全截断系统的使用现状温黄气田一期8口天然气井在2003年3月投产,气井的井口安全截断系统在使用8年半的时 I. INTRODUCTION The Haliburton wellhead safety shut-off system is an important safety equipment for gas production well stations and has become the standard configuration of well stations. Securing safety The function of the truncated system is effective and shortens its shut-in response time, which is of great significance to the safety of the well station. Better use of wellhead safety shut-off system, can effectively control the incident, reduce or avoid accident loss. Second, the use of wellhead safety truncated system status Wen-gas field a 8-well natural gas wells put into operation in March 2003, the wellhead safety cut-off system in the use of 8 and a half years
