Abstract: With the development of the oil industry, the organizational structures of the petroleum corporations are more complex, their delamination is more and more fine, and the development programming target is more complex. So, the former monolayer optimal models have many constraints on application, and can not meet with the demand of oilfield development programming indeed. In this paper, the in-out conjunctional relationship of dynamic index of both oilfield and oil extraction plant is established. Furthermore, the bi-level programming model to oilfield development, and the optimal bi-level models of oil production composition for different goals including the maximum oil production are firstly applied, the minimum cost and the maximum economic benefit in both layers are established. These models can be used to solve the problems about the optimal compositions for each subentry oil production, usually including natural production, measure production, oil production of new well in new blocks, oil production of new well in old blocks, and the corresponding workload and other development indexes of oilfield or oil production plant. The satisfactory economic benefit can be obtained in the application of the models to the development programming in several oilfields in the midlate stage.
