摘要
根据长庆油田低渗透油藏的开发实际,分析了开展三次采油技术攻关对于长庆油田实施跨越式发展,解决低渗透油藏的有效动用和已开发油田大幅度提高采收率问题的迫切性:初步评价了长庆油田主要含油层系实施三次采油的潜力;提出了长庆油田三叠系和休罗系油藏三次采油工作重点和技术发展方向,尽快形成具有长庆油田低渗透油藏特色的三次采油技术系列.
According to the Changqing oilfield actual development of low permeability reservoirs, analysis of EOR techniques to carry out research for the Changqing Oilfield Development modes to address the effective use of low permeability reservoirs and has developed a substantial increase in oil recovery problem urgency; preliminary, evaluation of the main oil-bearing strata of Changqing Oil Field implementation of enhanced oil recovery potential; proposed Changqing Oilfield Triassic and Jurassic reservoirs in enhaneed oil recovery technology fncus and direetinn, as soon as possible with the Changqing Oilfield low permeability reservoir characteristics of the tertiary oil recovery technology series.
