- 摘要:
- 川气东送管道是我国东西部地区的天然气管道大动脉，如何针对不同的管线、设备失效规律和特点开展风险量化评价是实施站场完整性管理的基础和关键。针对川气东送管道典型输气站场特点，制定了由风险预评估和检测、RBI、SIL与RCM分析组成的风险量化评价流程。根据站场管道流场模拟结果确定了站场重点检测对象和位置，结合川气东送管道站场的HSE管理目标提出了合理的可接受风险准则。利用建立的风险量化评价流程和方法，对普光首站的278个设备/管道项进行了风险量化评价，合理制定的风险控制与检验计划可有效防止失效事故的发生，从而有效提高川气东送管道站场的安全运行能力和完整性管理水平。
Sichuan-East Gas Pipeline is one of the most important pipelines in China's eastern and western regions. Conducting quantitative risk assessment according to different failure laws and characteristics of pipelines and equipment is the basis and key to implement integrity management on gas transportation stations. Analyzed are characteristics of typical gas transportation stations in Sichuan-East Gas Pipeline， developed is quantitative risk assessment process including risk pre-assessment and inspection， RBI， SIL and RCM analysis， determined are key inspected objects and their locations in gas transportation stations on the basis of in-station pipeline flow field simulation results and proposed is an acceptable risk criterion in combination with HSE management objectives of gas transportation stations in this pipeline. Adopted are the quantitative risk assessment process and method established already to conduct quantitative risk assessment on 278 items of equipment and pipelines in Puguang Gas Station and developed are reasonable risk control and inspection plans， which can effectively prevent failure of equipment and pipelines， enhance safety operation capacity of gas transportation stations in Sichuan-East Gas Pipeline and improve integrity management on these stations.
