摘要
应用拟压力和拟时间函数,提出了有界油藏具有变井储特征的多相流试井的数学模型,研制了压力降落与压力恢复的新的典型曲线。给出了试井分析方法;结合实例说明这种方法的有效性。
This paper presents a mathematical model for multiphase well test with changing well-bore storage in a closed reservoir by using pseudo pressure and pseudotime function,Newtype curves for pressure drawdown or buildup are given,a method of welI test analysis is pro-vided also. Illustrated by a field example in this paper shows that this method is efficient.
