Abstract: It is generally lack of semantics, relatively scattered and system imperfect in terms of the demand of geological knowledge. In order to solve the organization of geological knowledge standards, based on the domestic and foreign standards within the geological domain and the study of knowledge graph, and on the basis of the knowledge of stratigraphy and petroleum geology, two standardized models of geological knowledge map had been constructed. By taking stratum and petroleum geology as application background, knowledge mapping technology is used to verify them afterwards. It turns out that the proposed standardization can provide standard support for the standardization of geological knowledge organization.

Key words: geological field, geological knowledge, standard, standardization, sharing, knowledge graph
