摘要
Abstract
In numerical simulation of large scale fracture -cavern reservoirs, the large scale fracture and cavern are not suitable to act as continuous porous media. On the basis of mass conservation, a coupling model has been built by assuming Darcy flow outside the caverns and all equal pressure inside the caverns. The bottom hole pressure of such reservoirs is calculated by using direct boundary element method; the log - log pressure curve is mapped; and the effects of cavern size and distance to well, interporosity flow coefficient and storativity ratio on bottom hole pressure are discussed.关键词
