Considering the reservoir which external boundary was constant pressure we developed three- dimension steady state filtration model using the method of Fourier cosine transform and established coupling model between three-dimensional reservoir and well bore flow binding well bore pressure fall equation and coupling condition including the balanced flow and the equal pressure.
应用傅里叶余弦积分变换推导了外边界定压条件下水平井三维稳态油藏渗流模型,结合井筒内管流压降方程,根据油藏流入流量和水平井产出流量是物质平衡和井壁处油藏压力和井筒压力相等的耦合条件,建立了三维稳态油藏与井筒耦合渗流模型。
