非牛顿流体试井分析现状及展望

Advance of Well Test Analysis for a Reservoir With Non-Newtonian Fluid Flow.

从非牛顿流体油藏的分类、试井理论数学模型求解方法、试井分析解释方法三个方面回顾了非牛顿流体油藏试井分析的发展历程。指出了以三区复合油藏为模型基础,考虑中间过渡区存在的附加阻力是今后研究的主要方向。提出了非牛顿流体渗流过程中亟待解决的问题, 并对今后试井分析的发展进行了展望。

This paper reviews well test study for a reservoir with non-Nnewtonian fluid flow from three aspects: sort of reservoir with non-Newtonian fluid flow, the mathematical model and test data interpretation method. The present state and future trend of research are pointed out. It is best to combine composite reservoir of the triplicate region, in which transition zone additional resistance force in discontinuity locations. The existed problems in well test study for a reservoir with non-Newtonian fluid flow are presented and the future research is predicted.
