摘要
根据同步注水、超前注水7个方案进行模拟研究,拟合出超前注水中压力保持水平与超前注水时间的关系式,结合未饱和油藏开发的物质平衡方程和经济指标,导出超前注水开发低渗透油田中合理超前注水时间和极限注水时间的计算公式。并应用这两个公式对榆林油田的合理超前注水时间和极超前注水时间进行了计算。为超前注水技术中确定注水时机提供理论依据。
Simulation study is performed on seven simultaneous water injection and pre - water injection programs and a correlation between pressure maintenance level and the advanced water injection time is achieved through matching. Formulas are achieved for timing of rational advanced water injection and limit water injection in low permeability reservoirs. Practical calculation with these two equations is performed in Yulin oilfield and a theoretical basis is provided for the timing of water injection.
