Ignition Temperature and Stable Combustion Temperature of the In Situ Combustion Process

Abstract

The paper focuses on the high-temperature oxidation of a crude oil in a forward in-situ combustion process. The reaction conforms to Arrhenius prescription. Based on Semenov’s definition of ignition, equations for calculating the ignition temperature and stable combustion temperature are derived from the heat balance of the high-temperature oxidation. With previous experimental data, an average empirical parameter of the equations is calculated and two predictive equations are got. It’s concluded from the equations that these two temperatures of the reaction are only dependent on crude properties, and other factors in the reservoir have little influence on them.
