保障气田处理装置安全运行的方式为“检”“修”和“保养维护”。目前部分气田处理装置仍采取“一年一检修”的检修模式,提高检修频率更有利于掌握装置的运行情况；但高频率的检修不仅影响产量、增加检修成本,也会导致设施工艺参数的波动，容易引起设备故障。为探索气田处理装置长周期运行,对当前延长气田处理装置检修周期的关键制约因素开展了研究,明确了关键制约因素,并针对关键制约因素提出了优化策略;建立了特种设备定检日期优化方法。为企业开展气田处理装置延长检修周期工作提供了方法依据。

“Inspection”, “repair” and “maintenance” are the ways to ensure safe operation of natural gas treatment plant. At present, some gas field treatment plants still adopt the maintenance mode of “one maintenance shutdown per year”. While increasing the frequency of maintenance is more conducive in keeping track of the operating conditions of the plants, a high-frequency maintenance approach not only impacts production and raises costs but also causes fluctuations in process parameters of the facilities, which can easily lead to equipment failures. To explore long cycle operation of gas field treatment plants, this paper investigates the key constraints affecting the extension of operation cycle for these plants, identifies the critical restrictive factors, and proposes optimization strategies to address them. In addition, an optimization method of the scheduled inspection date of special equipment has been developed. These findings provide enterprises with a methodological basis for extending the interval between maintenance cycles of gas field treatment plants.
