1、 毕业论文毕业论文 题 目 二氧化碳提高采收率解析 班 级 08 级油采 摘摘 要要 提高采收率( EOR 或IOR) 研究是油气田开发永恒的主题之一。近几年由于油价 高涨,化学驱应用效益下降,而注气驱应用范围则连续增加，技术不断提高。中国油田 的储层属陆相沉积,非均质严重,原油粘度又比较高,上升很快,水驱采收率比较低,约 33%。 近期发现的石油储量又多属低渗透及高粘度等难采储量,发展提高采收率技术已 成为我国陆上石油工业继续发展的一项迫切战略任务。 同时随着人类社会的不断发展 和进步，由于温室气体大量排放而引起的全球气候变暖问题日趋严峻。然而，在中短 期内，没有其它合适的大规模能源能够替代
2、烃类能源，一种可行的方法是将CO2隔离 在地下，如注入气藏中，应用CO2提高采收率是埋存CO2的重要途径。 关键词关键词：提高采收率 注气 CO2 混相 AbstractAbstract Enhanced oil recovery (EOR or IOR) research is the development of oil and gas fields, one of the eternal theme. In todays world, still dominated by gas drive. In recent years, due to high oil prices, declin
3、ing effectiveness of the application of chemical flooding, gas injection and the continuous drive to increase the scope of application, technology continues to improve. Chinas oil reservoir is a continental deposit, non-homogeneous serious, and relatively high viscosity of crude oil rose rapidly in
4、relatively low recovery of water flooding, about 33%. The recent discovery of oil reserves is more low-permeability and high viscosity, such as recoverable reserves difficult, the development of enhanced oil recovery technology has become Chinas onshore oil industry to continue to develop an urgent
5、strategic task. At the same time as the continuous development of human society and progress, because a large number of emissions of greenhouse gases caused by the issue of global warming become more severe, we must take positive and effective measures. CO2 emissions reduction and control of CO2 con
6、tent in air protection of human existence has become an important aspect of the environment. However, in the short to medium term, there is no other suitable alternative to large-scale hydrocarbon energy to energy, a viable method is to isolate CO2 in the ground, such as the gas reservoir injection, the application of CO2 enhanced oil recovery is a major CO2 sequestration way.
