稠油热采牛顿/非牛顿渗流复合油藏试井解释模型

稠油油藏蒸汽吞吐热采井由于蒸汽波及区和未波及区流体的流动性质的差别，其试井问题必须采用复合模型，通过采用内区为牛顿流体，外区非牛顿流体的复合模型，分别求得了无限地层、封闭地层和定压地层三种情况下的拉氏空间解，并通过数值反演方法作出了相应的样板曲线，对于稠油开发油藏参数的求取提供了一种新的模型。

Well Test Interpretation Model of a Compound Reservoir with Non-Newtonian and Newtonian Fluid Flow in Dense Oil Well by Thermal Recovery

For the steam soak thermal production well of the heavy oil reservoir, because of the difference of flow property between the steam affected and the steam unaffected zone, compounding model to the question of well testing must be applied. Using a compounding model which inner zone is full of Newtonian fluid and outer zone is full of non-Newtonian fluid, the solutions of Laplace space in the case of infinite formation, enclosed formation and constant pressure formation could be obtained, and using the method of numerical inversion to figure out the corresponding type curves has been done which provides a new model for calculating parameters of oil reservoir development.
