Abstract: The theory of fluid displacement in a medium with doubleporosity has been generalized to include the effects of gravity into consideration.Various situations of fluid displacement in the gravitational field are thoroughly investigated,thereby giving a theoretical basis for efficient production of oil from carbonate reservoirs with bottom Water.
