Application of expert system alteration design on oilfield fl ooding pipeline network has been introduced in this paper. The correspond to oil field experience expert system knowledge base and expression have been establish ed, positive and negative mixed inference control strategies have been designed in this system. According to the conditions of production process, the schemes o f alteration design have been put forward. These cases have showed that best sch eme can be selected by the expert system. As a result flooding efficiency has be en enhanced and flooding radium has been reduced. The expert system has been bec ame a important tool for alteration design of oilfield flooding pipeline network .
