摘要: 采用组合系统方法提出裂缝控制油藏非牛顿幂律流体不稳定流动数学模型,并求出Laplace空间分析解,对于组合参数不同值给出该类油藏模型典型曲线,分析了早后期井底压力动态特征.从而可用于分析稠油或聚合物驱油藏流体流动参数及井周裂缝参数.

Abstract: According to the method of composite system,the mathematical model for non-newtonian power-law fluids in a fracture-dominated reservoir is proposed,and the analytic solution in the Laplace space is obtained.The typical curves for the kind of reservoir model with regard to various values of these composite parameters are put forward the dynamic behaviors of bottom hole pressure at early and late stage are analyzed.Hence,it can be used to analyze those parameters of flowing fluids and fractures in some heavy crude or polymer flooding reservoirs.
