注减氧空气驱油注气系统空压机爆炸风险分析

Analysis of Explosion Risk of Air Compressor in Oil Flooding System with Oxygen Reducing Air Injection

安全控制技术的不成熟限制了注减氧空气驱油的发展,而空压机作为注气系统的关键设备,其爆炸风险分析尤为重要。首先分析了引起空压机爆炸的风险因素并采用事故树分析法建立了以“空压机爆炸”作为顶上事件,“积碳引燃”、“积碳自燃”等为中间事件,以及25个基本事件的三级事故树。通过对基本事件的结构重要度分析得到引起空压机爆炸的4个主控因素,同时提出了相应的防护措施来有效的降低空压机爆炸事故的发生。

The immaturity of safety control technology has limited the development of oil displacement by air injection and reduction of oxygen.As the key equipment of air injection system,the explosion risk analysis of air compressor is particularly important.The risk factors of air compressor explosion were analyzed and a three-level fault tree with"air compressor explosion"as the top event,"carbon accumulation ignition"and"carbon accumulation spontaneous combustion"as the intermediate events,and 25 principal events was established.Four main control factors of air compressor explosion were obtained by analyzing the structural importance of basic events,and corresponding protective measures were put forward to effectively reduce the occurrence of air compressor explosion accidents.
