The invention relates to an intelligent retrieval method and system based on an exploration and development knowledge graph and a storage medium, and the method comprises the steps that a user inputs a retrieval statement, and after input information is processed, a keyword set of a query statement is extracted; performing one-to-one mapping on each keyword in the keyword set and concepts in the exploration and development knowledge graph to obtain a concept set sum; mapping the user retrieval information with the domain concepts, performing query expansion according to the relationship between the concepts, and determining a query expansion strategy of the user by calculating the similarity between the concepts; and querying each concept in the original concept and the extended concept by the semantic search engine, performing full-text retrieval of the document by using the concepts, and returning a concept query result and a document retrieval result after strategy sorting to a user. 本发明涉及一种基于勘探开发知识图谱的智能检索
