Mainly researches the basic method and algorithm of decision tree in data mining.In view of the requirement of the fault diagnosis in drilling project,combining with the characters of decision tree,proposes the drilling fault diagnosis expert system model based on the decision tree.It analyzes the characters of the drilling fault states,and it makes a detail discourse about the state of drilling process and the knowledge acquired,through the example with ID3,it implements the establishment of decision tree,which fixes the solid foundation for the expert system.At last proposes a method to improve the ID3 algorithm,and combining with the data processing result show that the decision tree algorithm based on data mining can recognize the different drilling states very well and implement the fault diagnosis.
