摘　　要：首次提出洞穴内两相流体动力学计算方法,并建立了洞穴与溶孔间的界面处理方法,创建了缝洞型油藏洞穴-溶孔耦合型两相流数学模型,研究了有限体积数值解法,编写了计算机应用程序,成功地应用于塔河缝洞型油藏注水驱油机理研究,首次提出了多井缝洞单元的注水开发模式,现场实施后增油效果显著。This paper firstly proposes the calculation method for inner cavern two-phase flow dynamics,develops the interfacial processing method between cavern and solution pore and builds up the cavern-solution pore coupling two-phase mathematics model for fracture-cavern reservoirs,including related finite volume numerical solution and PC-applied program.In successful application to study of water injection oil displacement mechanism of Tahe fracture-cavern reservoir in Tarim basin,the waterflooding process of multi-well fracture-cavern element is also proposed firstly,and the oil incremental effect is obvious after field implementation.
