摘要
建立了聚合物驱油藏考虑弹性效应的注聚井井底压力响应数学模型,通过有限差分算法对数学模型进行了数值求解。研究表明,考虑弹性效应时典型曲线过渡段上翘幅度大于不考虑弹性效应时的典型曲线,并且随着松弛时间和注入量的增大,过渡段上翘幅度逐渐增大,随着非牛顿指数减小,典型曲线整体上翘幅增大。
The pressure response model of the bottom hole for polymer flooding well is established. Finite difference method is adopted to acquire the numerical solution. The results indicate that the type curve considering elastic effect turns upward more obviously in the transition section than without considering elastic effect. Whit higher relaxation time and injection rate,the transition section shows bigger upturned amplitude. As non-Newtonian index decrease,the type cure increase the upturned amplitude.
