Research of knowledge model construction on downhole operation in oil fields based on ontology

A novel integrated framework for knowledge building of the oil field downhole operation is introduced based on the problems that the loaded data resources, poor knowledge sharing and decision support in this paper. Elementary techniques of the framework are elaborated in details, and an oil field ontology prototype system is drawn up and implemented based on the framework. The oil field downhole operation conception-ontology based on descriptor list and relational data are created, and some deeper semantic information with portability was mined. The experimental results demonstrate that the proposed method is applicable.
