英文摘要	Abstract In view of considering reservoir segregation, it is preferred that the permeability coarsening method is of great importance. Based on the mesh coarsening technique, the conceptual model of low permeability reservoir segregation distribution is established, and different permeability coarsening methods are selected to simulate the daily production of oil field and other parameters and the error analysis. The most appropriate permeability equivalent method and the grid step size are selected at last. It is concluded that the harmonic-arithmetic mean method is the best method to simulate errors of the parameters, and it is also the best way to calculate the equivalent permeability in low permeability reservoir considering the reservoir segregation distribution. After the coarsening, the grid step on horizon is 20 m or so and on vertical is 4-6m.
