水平裂缝压裂井试井分析

Well Test Analysis of Hydraulic Fractured Well with a Horizontal Fracture.

应用上下边界封闭无限大油藏的连续点源解 ,通过叠加获得了新的水平裂缝井压力响应的Laplace空间解 ,该拉氏解考虑了均质油藏和裂缝性油藏、井筒存储和表皮效应、垂直渗透率以及裂缝位置的影响 ,通过Stefest数值反演计算典型曲线 ,分析讨论了水平裂缝井的压力动态特征和参数估计方法。

A new Laplace space solution for the horizontal fractured well is developed by using continue source solution in infinite reservoir with bounded top and bottom boundary.The solution consider the effects of homogenous reservoir,pseudo-porosity reservoir,wellbore storage,skin effect,vertical permeability and orient of the fracture.The type curves are calculated by using Stefest inverse transform method.The pressure character and the parameter determine method are discussed.
