Abstract
Guyunji Oilfield is a waterflooding low permeability reservoir.This paper studies fluid percolation through numerical simulation and field mathematical statistics,analyzes the mechanism and response of future-oriented water injection in low permeability oilfield,and optimizes rational reservoir pressure,injection pressure,injection rate and timing,etc.,during future-oriented water injection.Field practice shows that future-oriented water injection can be very effective.
