Comprehensive Classification And Evaluation Method Of Daqing Peripheral Oilfields Reservoir

At present, Daqing peripheral oilfield have not yet carried out the study of reservoir classification and evaluation technology and there is no forming relevant technological achievements. This study bases on the research fruit of fine reservoir description technology in Daqing peripheral oilfield. Through the fine geological recognition of peripheral oilfield and according to the macroscopic characteristics of the reservoir, reservoir micro physical characteristics law and classification boundary, reservoir cracks, stress classification basis and classification methods, optimize the main geological characteristic parameters and weight coefficient which affect the storage, oil-bearing and developing effect of reservoir and research by categories. According to the reservoir classification methods through the math assessment, optimize the classification and evaluation method which adapts to the peripheral oilfield. Set up the reservoir geological classification comparison framework. According to the reservoir geological classification criteria, based on the optimization of reservoir evaluation parameters and through evaluation analysis method, evaluate the influencing factors of reservoir comprehensively and ultimately get a comprehensive evaluation indicators to study the reservoir by comprehensive classification and evaluation method .
