摘要
在信息化、数字化大背景条件下,油气田企业逐步实现了自动化生产,而工艺控制与安全联锁是实现自动化生产、保障安全的重要手段,应用越来越广泛。结合油气田企业生产管理模式和安全风险特点,提出工艺控制与安全联锁系统存在控制层级冗余、功能定位不清晰、关键设备可靠性较低以及报警数据闭环管理不到位等典型问题,通过控制单元对象来明确控制层级,“油公司”扁平化管理功能需求优化组态画面,关键设备控制元件冗余设置,提高设备可靠性能,以及报警数据从参数设置、状态动态抑制、设备故障状态的循环分析处理,解决生产报警洪流现象,制定气田工艺控制与安全联锁系统统一的层级划分规则以及控制逻辑思路,建立报警数据收集、分析、处置推荐流程,提升工艺控制与安全联锁系统性能,降低报警率,提高安全生产可靠性,为数字化气田深化建设和生产管理应用提供借鉴。
Under the background of informatization and digitalization,oil and gas field enterprises have gradually realized automatic production.Process control and safety interlocking are important means to realize automatic production and ensure safety,which are applied more and more widely.In combination with the production management mode and safety risk characteristics of oil and gas field enterprises,it is proposed that the process control and safety interlocking system has such typical problems as redundancy of control level,unclear function positioning,low reliability of key equipment,inadequate closed-loop management of alarm data,etc.By defining the control level through the control unit object,optimizing the configuration screen for"oil company"flat management function requirements,and setting redundant for control components of key equipment,the reliability and performance of the equipment can be improved.As well as,the cyclic analysis and processing of alarm data from parameter setting,state dynamic suppression,and equipment fault state can solve the production alarm flood phenomenon.The unified level division rules and control logic ideas of gas field process control and safety interlocking system are formulated,and the recommendation process of alarm data collection,analysis and disposal is established.The performance of process control and safety interlocking system is improved,alarm rate is reduced,and safety production reliability is greatly improved,which can provide a reference for the deepening construction of digital gas field and production management application.
