The Feasibility Study for Fracture-vuggy Carbonate Reservoir by Nitrogen Injection
The displacement of oil by water in Tahe oil field is at a high number of rounds. The WOC is rising and the oil displacement of effect by injecting water is deteriorating. The remaining oil called attic oil are mainly distributed in the structural relief of high position. The technology for exploitation of attic oil are available by injecting nitrogen or natural gas in foreign countries. The author operates the feasibility study for exploitation of fracture-vuggy carbonate reservoir by injecting nitrogen in order to enhance the development effect in Tahe oil filed. In view of the geological and production characteristics, we analyse the mechanism of enhanced recovery by nitrogen injection and favorable geological conditions; on the basis of multiphase flow in wellbore and numerical simulation, we demonstrate that it is available of enhancing recovery in fracture-vuggy carbonate reservoir by injecting nitrogen The result shows that 10% of enhanced recovery is available.
