为了提升煤层气田站场的完整性管理水平,对煤层气田某站场内工业管道及静设备进行RBI(risk?ased inspection)评价及风险计算。评价发现,站内弯头失效概率和压缩机出口埋地管道失效风险相对较高,进而对失效概率较高的弯头和失效风险较高的压缩机出口埋地管道腐蚀情况进行分析。结果表明,站内弯头处于气相环境和液相环境时,其腐蚀速率均属于中度腐蚀速率,可采取定期壁厚监测;压缩机出口处埋地管道外防腐层受高温和震动影响容易失效,存在弥散型腐蚀坑,采取的方案为更换耐高温、粘接力好的防腐材料。在后续煤层气田站场完整性管理工作中,可将本次RBI评价、风险计算、研究结果和方案配置作为参考。

In order to improve the integrity management of coalbed methane field stations, RBI (risk?ased inspection) evaluation and risk calculation were conducted on industrial pipelines and unmovable equipment in a coal seam gas field station. It was found that the failure probability of elbow in the station and the failure risk of the buried pipeline at the compressor outlet were relatively high. The corrosion of the elbow with high probability of failure and the buried pipeline with high risk of failure are analyzed. The results show that the corrosion rate of the elbow in the station is moderate when it is in the gas phase environment and the liquid phase environment, and the wall thickness corrosion monitoring can be taken regularly. The external anticorrosive layer of the buried pipeline at the compressor outlet is prone to failure due to the influence of high temperature and target, resulting in a dispersion corrosion pit. The solution adopted is to replace the anticorrosive material with heat resisting and good adhesion. In the subsequent integrity management of coalbed methane field stations, the RBI evaluation, risk calculation, research results and scheme configuration can be used as a reference for application in coalbed methane field stations.
