Abstract

Abstract: A device for measuring explosion limit for flammable gas is developed.The explosion limit for the gas produced after air injection low temperature crude oil oxidation is obtained,and the maximum oxygen content is also tested through changing the gas content.The results show that the gas prepared according to the low temperature oxidation will not explode under the condition of reservoirs,the explosion limit and maximum oxygen content change with the temperature and pressure,carbon dioxide plays an important role in impeding the explosion of the flammable gas.

Key words: air injection, low temperature oxidation, oil oxidation, explosion limit, maximum oxygen content
