Abstract: The study of the characters and the influencing factors of the low permeable sandstone reservoirs relative permeability curve is not only the important approach to analyze and recognize the rule of oil and water fluid percolation, but also the base of proper development petroleum. By summarizing the futures of the relative permeability curve in low permeable reservoirs and study of the futures of relative permeability curve in lithic arenite which rock fragments are most come from tuff and lava, it is the reservoirs rock character, the type of detrital minerals, the degree of grains coarse and the lay out of clay mineral that are main influencing factors which influence the relative permeability curve. This conclusion has great significance in proper development in this kind of low permeable oil reservoirs.
