摘要
通过对聚合物溶液特性进行研究, 利用幂律模式绘制了幂律指数与稠度系数随
聚合物浓度、温度变化的关系图版。以非牛顿流体流变学和采油工程理论为基础, 从幂律流体
的运动方程出发, 结合连续性方程和状态方程, 推导了幂律流体在多孔介质中稳定渗流的油井
流入动态方程, 并对其进行动态拟和得到了便于现场应用的聚合物驱油井流入动态模型。该
模型的计算值与实测值吻合较好, 预测油井产能是可靠的。
Abstract
Research for the character istics of po lym er liqu id is conduc ted through experim ents. Chart board drawn by pow er - law m ode l show s the re lationship between powe r - law index and consistency co efficient vary w ith po lym er concentration, temperature. A ccording to non - New ton ian flu id rheo logy and petro leum eng ineer ing theory and using the m otion equation of power- law fluid, continu ity equation and sta te- equa tion, w e can derive the dynam ic equa tion of pow er - law flu id stabilized flow in the po rousm edium. Fina lly, w e ge t the dynam ic m ode l of po lym er flooding. Its ca lcu la tion va lue and surveying va lue are identica,l wh ich is re liab le to pred ict the o il production.
