基于层次分析法的CO2驱注采工程安全风险评价
Evaluation on the safety risk in the injection and production engineering of CO2flooding based on analytical hierarchy process
摘要
Abstract
Safety risk management of injection and production engineering is the key part of field application of CO2 flooding technology. To ensure the on-site injection and production safety of CO2 flooding and improve the safety risk management level of injection and production engineering, the safety risks in the process of injection and production were analyzed. Besides, the safety risks of injection and production engineering were evaluated quantitatively by means of analytical hierarchy process, and the hierarchical structure model of safety risk in the injection and production engineering of CO2 flooding was established. Then, the factors influencing the safety risks of injection and production engineering were ranked based on structure judgement matrix, consistency check and weight calculation. The safety risks in the injection and production engineering of CO2 flooding are divided into injection and production risk,CO2 corrosion risk, safety management risk, and environmental protection and personal safety risk. The quantitative evaluation on the safety risk in injection and production engineering of CO2 flooding shows that CO2 corrosion is the greatest safety risk in the injection and production engineering of CO2 flooding and the constructors' safety consciousness is the main factor influencing the safety of injec-tion and production engineering. The quantitative analysis and evaluation on the safety risk of engineering and production engineering provides the reliable basis for the safety risk decision making and management of CO2 flooding, decreases the safety risk in the injection and production engineering of CO2 flooding effectively and provides the guidance for the safe operation of injection and production.关键词
