Key Technology of Explosion Prevention in Air Injection EOR Process

Abstract:

The article aims at researching on anti-explosion security technique for gas-injection well of air oil drive through the gas associated with crude oil alerting system, and then, making sure safety distance of associated gas explosion. Firstly, experiment the explosion limit of associated gas, then to determine the different alerting threshold and the arrangement of inspection instrument, which are on the basic of different limit requirements of density about gas-injection well head and internal gas-injection well. Secondly, with associated gas explosion in the well, calculate the overpressure of well head through simulation method. Finally, analogy between explosion energy and TNT equivalent, so that determine the level of people casualties and structure breakage for safe distance according to failure criteria of explosive blast.
