摘要
复杂油气生产设备实质为一个开放系统,设备各个部件及故障之间具有耦合相关性,并具有多重故障传播路径。针对设备运行安全、效益和维修损失,综合分析油气生产设备停机损失、最小维修费用、事后更换费用、预防性更换费用、机会更新费用等参数对维修决策的影响,提出一种故障超前防御的全局优选机会维护模型。该模型揭示超前防御位置、超前防御时间、超前防御方式以及超前防御判据,形成一套油气生产设备故障的安全预警维护机制,将单部件故障这种不利的随机因素转换为对其他单点进行故障超前防御的有利机会,从而降低系统全局故障损失,成为一种复杂系统故障预警防御的新方法。
The essence of the complex oil and gas production equipment can be considered as an open system. There exist coupling relationship between various parts of the equipment and also different faults, which result in multiple fault propagation paths. Considering the safety, benefits and maintenance loss, parameters such as downtime losses, minimum maintenance costs, corrective, preventive and opportunistic replacement costs, are analyzed comprehensively to investigate the influence of different maintenance strategies. An opportunistic maintenance model based on fault preventive defense is proposed in the paper, which determines the defensive positions, time, styles and criterion, developing a failure early-warning maintenance mechanism of oil and gas production equipment. It helps to convert the negative random factors caused by single fault to a favorable opportunity of fault prevention for other components in advance, so the overall fault losses can be reduced.
