Abstract: 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 fracturecavern 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 fracturecavern element is also proposed firstly, and the oil incremental effect is obvious after field implementation.

Key words: fracture-cavern reservoir, numerical simulation, mathematics model, fracture-cavern element waterflooding process
