  • The Ordovician gas condensate reservoir in D area of Tahe is a main gas reservoir in the Tahe oil field. The gas production in D2 well area has been decreasing rapidly in recent years. How to improve the recovery rate of such gas reservoir is a difficult problem to be solved in the continuous and efficient development of block. According to reservoir and production characteristics, we analyzed water injection mechanism, provided a base of selecting water injection well, identified the best time and application scope of water injection, used a material balance method to study the relationship between water injection and pressure recovery and recoverable reserves, determined a reasonable water injection amount, and finally provided a complete technique for water injection in gas well. Field practice showed that water injection could effectively improve the fractured-vuggy carbonate condensate gas recovery.
