摘要
古云集油田为注水开发的低渗透油藏,利用数值模拟和矿场数理统计对该油藏的渗流规律进行了研究,对低渗透油田超前注水的机理和开发效果进行了分析,并优选了超前注水期合理地层压力的保持水平、注水压力、注水强度、注水时机等相关参数。现场实践结果表明,超前注水技术应用后可取得较好的开发效果。
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.
