摘　　要：沉积相是地质学中一个不可或缺的研究部分,对油气勘探和地层分析具有重要的意义。本体是一种能在语义和知识层次上描述信息系统的概念模型建模工具。许多学科领域已经建立独立的领域本体,并在本体基础上建立相应的领域知识库。论文针对地质学中沉积相领域,首先构建沉积相本体,进而在本体基础上利用Jena建立沉积相知识库。该知识库架构分为图片层与知识层。其中,知识层是以沉积相本体为基础,具有知识查询与语义识别两个功能。图片层以专业图片库为基础,具有自动扩充与图片查询两个功能。该沉积相知识库可为相关地质研究人员提供参考与借鉴,对领域本体知识库构建具有一定的参考意义。Sedimentary facies is an indispensable part of geology,which is of great significance to oil and gas exploration and stratigraphic analysis.Ontology is a conceptual modeling tool for describing information systems at the semantic and knowledge levels.Many disciplines have established independent domain ontology,and established corresponding domain knowledge based on ontology.In this paper,combining with the field of sedimentary facies in geology,the ontology of sedimentary facies is first constructed,and then the knowledge base of sedimentary facies is established by Jena technology.The knowledge base structure is divided into picture layer and knowledge layer.The knowledge layer is based on the ontology of sedimentary facies,and has two functions:knowledge query and semantic recognition.The picture layer is based on professional picture library,and has two functions:automatic expansion and picture query.The knowledge base of sedimentary facies can be used for reference by relevant geologists and has certain reference significance for the construction of domain ontology knowledge-based system.
