得到了非均质油藏垂直水力压裂井压力瞬变特性的解析解。利用分形几何的概念对储层的非均质性进行了建模。这种储集层称为分形储集层。根据分数阶微积分理论，采用时间分数阶导数来反映分形储层的记忆性质。通过各种综合算例，充分研究了不同参数对计算井筒压力的影响。
We obtain an analytical solution for the pressure-transient behavior of a vertically hydraulic fractured well in a heterogeneous reservoir. The heterogeneity of the reservoir is modeled by using the concept of fractal geometry. Such reservoirs are called fractal reservoirs. According to the theory of fractional calculus, a temporal fractional derivative is applied to incorporate the memory properties of the fractal reservoir. The effect of different parameters on the computed wellbore pressure is fully investigated by various synthetic examples.
