摘要
本文建立了考虑井筒附近存在高速非达西渗流的孔隙性油藏油井的试井解释模型,采用有限差分方法,求解了无因次数学模型。研究了高速非达西渗流的特征,作出考虑高速非达西渗流影响的理论图版,包括压力图版和压力导数图版。同时,利用无因次数学模型的简化解,指出井底附近地层存在污染(或改善)的复合油藏压力导数特征,研制出新型理论图版。文中结合实例,说明本文理论图版的应用方法。
A new interpretation model is prosposed applicable to a composite reservoir with turblence near wellborn. Finite-difference solutions of its mathematical model are obtained that introduces a new set of type curves for short time transient analysis. In special case, the behavior shows that either damage or improvement in a composite reservoir can be diagnosed. A pratical field example is presented to illustrate the use of new type curves.
