A mathematical mergence model based on decision level data fusion and evidence theory was developed for formation damage diagnosis by analyzing the features of multiple source information of formation damages.The concrete algorithm of the data fusion in decision level was presented.By analyzing and diagnosing the water sensitivity of a reservior,the reservior information from multi-sources which reflects the formation damage types was processed comprehensively by the model,and the formation damage types were judged systemically.The accuracy and reliability of formation damage diagnosis can be effectively improved.
