N2 - High pressure air injection (HPAI) has been proven as an enhanced oil recovery process in many fields. The reactions associated with crude oil and oxygen are the main difference between HPAI and other gas injection processes. In order to study the reaction schemes, different experiments, such as the combustion tube, kinetic cell, accelerating rate calorimeter, and thermogravimetry analysis, are conducted. In this paper, a reaction scheme is build that includes three classes of reactions: low-temperature oxidation, cracking, and combustion. We then use simulation models with the proposed reaction scheme included to history match the data from a combustion tube experiment and a kinetic cell experiment. It is demonstrated that the reaction scheme is valid. Based on this study, lumping the crude oil into four pseudocomponents brings a good matching result, and the kinetic parameters are obtained through matching the experimental results.
