Reservoir Parameters' Simulation Study on Air Injection with Low Temperature

注空气低温氧化技术是一项有效的提高采收率技术,空气具有资源丰富,成本低廉,应用范围广等优点。针对某油藏进行了注空气低温氧化过程模拟,对储层韵律、地层倾角、含油饱和度等方面进行数值模拟研究,分析不同地质参数对注空气低温氧化开发效果的影响,得出适合空气低温氧化油藏的主要油藏参数要求,为该油藏空气驱提高采收率方案提供依据。

Air injection is an effective EOR method.There are many favorable characteristics on air,such as abundance,easy to obtain and cheap and used widely.In this paper,the idea simulation reservoir model has been built to simulate the air injection with low temperature process.Relative parameters including rules of rhyming,reservoir dip and oil saturation of oil layer have been analyzed to study the performance of different parameters.It provides the basis of the air injection and reference for similar reservoir's development.
