Abstract: During the development of large oilfields, the geological reserves structure has changed with the continuous investment of different types of new reserves, and the key indicators that characterize the overall development technology and economic effect of the oilfield, such as production, recoverable reserves, recovery ratio, and reserve-production ratio, development costs, operating costs, etc. have also changed, and the law of change can be described with a set of mathematical models. Based on the forecast of development indicators, the optimization of new production blocks is conducted using the multi-attribute decision-making methods. The application example shows that the method is practical and highly maneuverable, and can provide an important method for the prediction of technical and economic indicators, the optimization of used reserves, and the development and investment decision-making. Finally, we give suggestions of giving priority to the development of integrated, fault-block and special lithological reservoirs, developing low-permeability tight reservoirs low-cost development technology, and promoting water flooding and heavy oil reservoir management and technological innovation are given.

Key words: geological reserve structure, development index prediction, multi-attribute decision-making, block combination plan
