摘要
流线模拟是一种辅助数值模拟方法,能够清晰直观地展示油藏流体在地下的流动状况。为了定量研究油藏注水井组配注量,应用ResAssist_C流线模拟软件,结合海外某一实际底水油藏进行了模拟研究,计算得出井组中注水井劈分系数及地层流体流动方向,再结合实际产量和优化出的注采比,提出一种用流线模拟劈分系数计算水井配注量的方法,与现场实际配注量进行对比分析,通过适当调整,得出最优配注量。由流线模拟得出水井配注量,可减少无效注水,提高了注入水利用率和水驱效率,为油田现场施工操作提供帮助和参考。
Streamline simulation was an assistant method of numerical simulation.It can directly show the flowing status of fluid in the reservoirs clearly.In order to research the quantity of injection allocation in injection well,numerical simulation was performed on a bottom water reservoir abroad by using ResAssist_C streamline simulation software,the split factor of injection well and the fluid flowing direction were calculated.Combined with the actual production and optimized injection-production ratio,a method for calculating the injection allocation by the split factor was presented.Compared with the actual injection allocation in oilfield,the best injection allocation is obtained for injection wells through appropriate adjustments.The injection allocation quantity obtained from streamline simulation can reduce the ineffective injection water,improve the efficiency of waterflooding,and provide help and reference for the oilfield operations.
