摘要
可动凝胶型聚合物驱油在实际生产措施过程中,不同的注入参数对开发效果的影响较大。本文在考虑可动凝胶聚合物强度、粘度变化的同时,考虑了可流动性等重要因素,形成了三维三相十组分可动凝胶型聚合物驱数值模拟器。针对胜利油田凝胶型聚合物驱先导试验区,进行了注入参数的敏感性数值模拟研究,生产历史拟合符合率高。并模拟分析了可动凝胶型聚合物注入体积、段塞组合、残余阻力系数及注入不可动凝胶对比等敏感性参数,预测了不同注入参数的影响效果,对进一步开展可动凝胶型聚合物驱油措施具有重要指导意义。
The performance prediction of flowing gel for profile control is based on the result of reservoir numerical simulation. A new model for predicting performance of flowing gel was proposed. This model can be used to predict many production indexes such as water cut, oil production rate and water production rate. It can also be used to predict the parameters of enhanced oil recovery, increment of oil volume and reduction of water volume in profile control of flowing gel. The new method can provide the bases for pilot project design and prediction of application. The sensitivity of parameters in the model was analyzed. This model was applied to prediet the result of a group of oil wells.
