通过对多种类型的有限导流裂缝水平井瞬时压力模型的背景研究,论述了有限导流裂缝水平井问题的多个关键难点,并对于此问题的解决方法进行讨论,对其可行性进行了探讨。综合分析并讨论了影响有限导流裂缝水平井瞬时压力的多种制约因素,提出利用混合的裂缝模型可有效研究裂缝特征对单条有限导流水平井裂缝瞬时压力的影响。

By studying of the background of several type models for the horizontal well intercepted by a finite-conductivity fracture,a number of key difficulties in pressure analysis of such horizontal wells and the methods for solving those key difficulties are discussed. A variety of constraints factors for the transient pressure of horizontal wells intercepted by a finite-conductivity fracture are also comprehensively analyzed and discussed. A mixed fracture model is used to analyze efficiently the influence of fracture properties to the transient pressure of horizontal wells intercepted by a finite-conductivity fracture.
