摘　　要：为保障普光气田的安全平稳运行和川气东送供气平衡,针对气田一级关断联锁逻辑关联性紧密、制约性强以及外输系统压力变化对上游的不利影响因素,开展了危险与可操作性分析以及系统可靠性验算,同时有针对性地研究了高压大流量产品气安全放空控制技术。降低了SIS系统意外跳车频率,实现了外输首站压缩机故障停机压力安全快速泄放。In order to ensure the safe and stable operation of Puguang gas field and the balance of gas transmission from Sichuan to East,the logic of the first level shut-off interlock of the gas field is closely related and restrictive,and the adverse impact of the pressure change of the export system on the upstream;Carry out hazard and operability analysis and system reliability check calculation,and study the safety venting control technology of high-pressure and large flow product gas;Reduce the frequency of unexpected trip of SIS system,and realize the safe and rapid release of pressure during the failure shutdown of compressor in the initial export station.
