摘要
针对缝洞型储层系统的特点,提出了研究这类流动规律的基本思路:将缝洞型储层系统分解为溶洞单元和裂缝单元,它们交替连接组成了整个储层流动系统;溶洞单元中的流动看成是管道流动,裂缝单元中的流动遵循达西定律.根据这个思路,研究了平面内缝洞耦合线性流动机理,建立了平面内线性流动的物理模型、数学模型及其数值求解方法.
In accrodance with the characteristics of vuggy reservoirs,a basic idea for studying the flow law in this kind of media is put forward:this kind of vuggy reservoir system is decomposed into vug units and fracture units,the two kinds of units alternatively connect and consist of the total reservior system.The flow in vug units is considered as channel flow or piping flow,and the flow in fracture units as seepage and follows Darcy law.Based on this idea,the planar linear flow theory of vuggy reservoirs is established,and the corresponding physical model,mathematical model and its numerical solving method are prsented respectively.
