摘　　要：首次对低渗透油田压裂增产过程中一氧化碳气体生成机理进行了综合研究。研究表明,高能气体压裂配方本身及高能气体压裂产生的高温气体与伴生气或原油发生二次化学反应是产生一氧化碳及其它有毒、有害气体的主要因素,同时给出了生成机理。此项研究对采取有效的防治措施和合理开发同类油田具有十分重要的指导意义。The generation mechanism of CO during fracturing stimulation in low permeability reservoir is first studied in this paper.The study indicates that the main factors of producing CO and other poisonous gases include HEGF formula itself and secondary chemical reaction between high temperature gas of HEGF and reservoir associated gas and oil.This study is of great theoretical value to explain the generation mechanism of CO in low permeability reservoirs,and is helpful for rationally developing similar oil fields.
