摘要: 对低渗透油藏高能气体压裂增产措施过程中一氧化碳气体生成机制进行的综合研究表明,高能气体压裂配方及高能气体压裂中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他有毒有害气体的主要因素。在此基础上,建立了一氧化碳井筒流动及井口扩散模型,给出了中毒防治措施。此项研究为低渗透油藏增产措施中一氧化碳气体的生成机理及采取有效的防治措施提供了理论依据,对同类油藏高能气体压裂增产安全措施具有重要的指导意义。

Abstract: The formation mechanism of carbon monoxide in high-energy gas fracturing(HFGF)of low-permeability reservoirs was studied.The result indicated that carbon monoxide and other poisoning gases were resulted from HFGF and high-temperature gases of HFGF reaction with reservoir associated gases and crude oil.On the basis of this,the mathematical models of carbon monoxide flow and diffusion in wellbore were established.The poisoning reinforcement measures of carbon monoxide were presented.The study is theoretically valuable to explain the formation mechanism and reinforcement of carbon monoxide for stimulation treatment of low-permeability reservoirs,and is instructive for safe stimulation treatment of HFGF in similar reservoirs.

Key words: low-permeability reser voirs, high-energy gas fracturing, carbon monoxide, formation mechanism, mathematical model
