具有环形窜流带的地质模型解析解

The Analytic Solutions of a Geological Model with Ringlike Vertical Crossflow Area

研究一种新型的地质油藏模型，给出了解析解，并讨论了解的近似结构；利用Stehfest数值反演将解析解与近似解进行了对照，效果很好。

The authors determine the solutions of a new type of well-test model withringlike vertical crossflow area, and discuss the approximate solutions. By Stehfest's method, theapproximate Solutions are Verified.
