Research of the extension classification method and classification of flow units

LI Qin1,WANG Guo-hui2,CHEN Qing-hua1(1.The Library of The China University of Petroleum,Dongying 257061,China;2 Shengli Engineering and Consulting Co·Ltd·,Dongying 257026,China)  
Extenics is a subject which study the extensive possibility of things and the extensive rules and extensive methods.Extenics can be used to solve contradiction problems.The extension classification method is a dynamic classification method which is based on the extennics theory to study the thing's classification characteristics.The paper discussed the use of the extension classification method in the classifying of the flow units.The result of the extension classification is more precise than that of the grey association cluster method.And the extension classification method have stonger judging capability and lower the misjudgment rate.The extension classification method must be a wide useful method in oil exploration and exploitation.
