Abstract: By considering all the involved processes of oil production,this paper presents optimum study and systemic methods of oilfield development planning,using prediction theory,optimization theory,economic evaluation method,comprehensive evaluation theory and computer technique.Especially,in order to meet various planning requirements three kinds of oilfield development planning models are set up and also resolved by non-linear planning method,they are minimal cost model for a given total oil production rate,profit and loss balance model and maximal profit model.In addition,because of the limits of five year planning model used widely,a year by year planning model is developed,based on the prediction model of flow rate regression and natural degression rate regression.Based on the study,a PC simulator of oilfield development planning is developed,which can be used for predicting oilfield development indexes、confirmming the optimal allocation of production structure in PetroChina level and production optimal allocation to all the oilfields determining comprehensive queue of oilfield development projects and the best investment structure.Recently the simulator was used for the 2000—2005 development planning of PetroChina with satisfactory results.
