Abstract: The effects of production rate,oil formation sedimentary rhythm,ratio of vertical to horizontal permeability,size and position of an impervious break,volume of edge and bottom water,ratio of oil to water viscosity,well spacing,perforation interval and capillary pressure on the production performace of a sandstone reservoir with bottom water were studied and analyzed with numerical simulation.The bottom water movement with impervious break in different vertical to horizontal permeability ratio were also simulated.The results indicated that the size and position of an impervious break,vertical to horizontal permeability ratio.oil to water mobility ratio and production rate are critical parameters that affect the water coning behavior in sandstone reservoirs with waterdrive.Water coning are not usually formed in sandstone reservoir with bottom water.

Key words: sandstone, bottom water reservoir, water coning, mechanism, tactics
