摘要
注空气技术是低渗油藏提高原油采收率的重要技术手段之一。分析注空气提高采收率机理及注空气过程中原油氧化反应机理,综述了原油低温氧化反应模型,为氧化动力学参数的计算提供理论依据。进一步分析蒸汽、压力、原油性质及储层岩石对低温氧化反应的影响。
Air injection is one of the important processes to enhance oil recovery. In this paper, on the basis of lit- erature researches, the mechanism of high pressure air injection (HPAI) and low temperature oxidation (LTO) are summarized. The reaction process between high pressure air and formation is analyzed in details, and the LTO re- action model is established, which provides a theoretical basis for the calculation of oxidation kinetics parameter. By investigating the effect of vapor phase, pressure, oil properties and reservoir lithology on low temperature oxida- tion, foreign air injection technologies have great significance for the development of low permeability oil reservoir.
