Dual-factor method for development optimization of oil shale bearing fields

Abstract：China has abundant oil shale resources. The utilization of these resources requires the development of oil shale resources on the scientific and rational basis. It is thus necessary to conduct optimization of oil shale bearing fields, which can provide scientific evidence for strategic planning and rational exploitation of oil shale, thus achieving optimal decision. The dual-factor method for development optimization of oil shale bearing fields is based on the idea that oil shale resources should be strategically planned through appraising geological resources and technical economy of the oil shale bearing field. Based on a study of factors controlling geological resources and technical economy of oil shale resource development and utilization, the authors quantitatively calculated weight of parameters by analytical hierarchy process, calculated score of geological resources and technical economic factors according to parameter features of the oil shale bearing field, and then evaluated superiority and inferiority of oil shale bearing fields according to the score of dual-factor and the planning development rank of the oil shale field. This method makes up the shortcoming of the aggregate index evaluate method
