Kinetics of low temperature oxidation of light oil in air injection process
摘要
Abstract
Air injection process is an effective secondary oil recovery method for deep and light-oil reservoirs with very low permeability and poor water injection. During air injection, low temperature oxidation (LTO) may occur between a small fraction of reservoir oil and oxygen within injected air to produce flue gas ( N2 and CO2 ) and oxygenated products. An improved LTO reaction model was established through analyzing light-oil LTO mechanisms. The kinetic parameters, in terms of the Arrhenius activation energy and reaction frequency factor, were obtained from the results of small batch reactor experiments. The improved LTO reaction model and the derived kinetic parameters were verified by history match of oxidation tube experiments using a thermal reservoir simulation model. The influence of reservoir core on LTO was investigated. The reaction with reservoir core materials has lower Arrhenius activation energy and higher frequency factor than that with oil only.关键词
