Abstract: The reserveproduction ratio is a very important proportion parameter of the petroleum industry and closely related to exploitation situation. Based on the concept of the reserveproduction ratio, we applied the reserve replacement ratio to analyze the change law of reserveproduction ratio with the change of the reserves and productions. On the basis of the practical development dates and static parameters of 44 oil fields in 13 oil areas, 3 types were divided of heavy oil reservoir，low permeability reservoir and normal water drive sandstone reservoir. It was concluded that the reasonable reserveproduction ratio, by the divided criterion of development stages in the paper, and the quantitative relationships were obtained, and it served as the development planning of the same reservoir type, and it had a theoretical and practical significativeness for the oil field development.

Key words: reserveproduction ratio, decline rate, development phase, oil reservoir type, reserve replacement ratio
