考虑井筒储集的油水两相流试井分析

Well Test Analysis for Water and Oil Two Phase Flow with Wellbore Storage.

油水两相流在油田中广泛存在 ,但目前常用的研究方法中没有考虑井筒储集效应的影响。鉴于这种情况 ,本文将井筒储集系数和表皮系数引入油水两相流数学模型中 ,并用数值模拟方法求出数值解。经实例验证 ,此方法行之有效。

Although there are water-oil two phase flow in oilfield,the universal methods for well test analysis haven't consider the wellbore storage.Based on this reason,a new model with wellbore storage and skin effect is developed.The numerical solution is calculated by using numerical simulation method.The example analysis shows that theis method is useful.
