Abstract
When specific static analysis in oil reservoir engineering aspects and an analysis evaluation method are utilized to assist people in conducting operation of oil-gas reservoir prediction, dynamic analysis, dynamic evaluation, analysis, early warning and the like, the operation of updating the functions of an oil-gas exploration prediction and oil reservoir collaborative management decision system and installing and configuring the system is very complex due to uncertainty of the number of control factors and varieties. By the adoption of the method, the whole prediction and decision process is abstract, logic modules of data normalization processing, data dynamic mapping, multi-well space relation analysis and the like are specially set up, the complexity generated by the uncertainty of the number of the factors and the varieties of the prediction and decision method is shielded outside a main analysis module, and the complexity of the operation of updating the functions of a space analysis system and installing and configuring the system is reduced.
