In this paper, blast effect of oil-associated gas in injection wells is determined when using air displacement, and on basis, the relevant safety distance also. Numerical simulation used to calculate overpressure distribution, explosion energy TNT equivalence combustible wells. Based shock wave damage criterion, distances seven levels are obtained, which personnel minor injuries, severe death, destruction buildings with mild, moderate, manage destroying. Therefore, technical support provided accident prevention, emergency rescue.
