Simulation results indicate that the initial temperature of the high temperature core has an important effect on the ignition delay time and the early combustion phase of the premixed CH4-O2-N2 mixture,but it hardly affects the CJ deflagration phase.

But on the other hand, air drilling adopted air as the circular medium and so hydrocarbons like natural gas and oil mixed with air will cause downhole explosion if only the mixture reaches the explosion limit under any possible explosive condition, which will certainly threaten the safety during operations of air drilling.
