摘　　要：Flow characteristics of both oil and water in a horizontal pipe are the basic information for the design of crude oil transportation and production profile logging.The flow characteristics are more complicated when oil or water carries sediment particles.In order to simulate the distribution of flow characteristic parameters of water-or oil-sediment mixture in a horizontal pipe,the governing equations and the boundary condition for the mixture phase of water-or oil-sediment were established by the mixture algebraic slip model (MASM) based on the Eulerian description method,and the numerical solution was obtained by the finite difference method and successive over relaxation (SOR).The simulation results indicated that the mainstream velocity moved downwards with increasing volume fraction of the particle phase and decreased with reducing pressure drop.The distributions of the volume fraction of the particle phase in the circular cross section were related to the mainstream velocity,and the volume fraction values increased downwards and sidewards with reducing mainstream velocity.Moreover the mainstream velocity of the oil-sediment mixture phase was larger than that of the water-sediment mixture phase.The mixture algebraic slip model could well simulate the flow characteristic parameters of the mixture phase with higher computing efficiency.Flow characteristics of both oil and water in a horizontal pipe are the basic information for the design of crude oil transportation and production profile logging. The flow characteristics are more complicated when oil or water carries sediment particles. In order to simulate the distribution of flow characteristic parameters of water- or oil-sediment mixture in a horizontal pipe, the governing equations and the boundary condition for the mixture phase of water- or oil-sediment were established by the mixture algebraic slip model （MASM） based on the Eulerian description method, and the numerical solution was obtained by the finite difference method and successive over relaxation （SOR）. The simulation results indicated that the mainstream velocity moved downwards with increasing volume fraction of the particle phase and decreased with reducing pressure drop. The distributions of the volume fraction of the particle phase in the circular cross section were related to the mainstream velocity, and the volume fraction values increased downwards and sidewards with reducing mainstream velocity. Moreover the mainstream velocity of the oil-sediment mixture phase was larger than that of the water-sediment mixture phase. The mixture algebraic slip model could well simulate the flow characteristic parameters of the mixture phase with higher computing efficiency.
