| Abstract: |
| A mathematical mergence model based on decision level ciata fusion and evidence iheory was developed for formation damage diagnosis by analyzing the features of multiple source information of foimation damages. The concrete algorithm of the data fusion in decision Ifivel was presented. By analyzing and diagnosing the water sensitivity of a reservior, the; re-servior information from muUi-^ources which reflate the formation damage types was processed comprehensively by the model? and the formalion damage types were judged systemicdly. The accuracy and reliability of formation damage diagnosis can be effectively improved. |
| Key words: formation damage diagnosis and protection information fusion evidence theory |
