Knowledge graph-based oil and gas reserve report generation method, device and equipment

The invention discloses an oil and gas reserve report generation method, device and equipment based on a knowledge graph. The method comprises the following steps: in response to a report generation instruction, determining a corresponding primary template from pre-constructed report templates according to an obtained report type selected by a user; determining a template type and a template label of each corresponding secondary template according to each chapter label of the primary template; determining a preset degree of freedom corresponding to the secondary template according to the template type of the secondary template; obtaining a knowledge graph entity; wherein the knowledge graph entity is determined based on oil and gas reserve knowledge and a pre-constructed knowledge graph ontology; obtaining report data associated with the secondary template from the knowledge graph entity based on a pre-constructed mapping relationship between the template label and the knowledge graph entity; and according to
