摘　　要：圈闭评价在油气勘探风险防范和可行性评估中的关键过程,标志着油田领域对于圈闭评价知识需求越来越高。然而在面对圈闭评价众多知识资源时,其知识却呈现知识表示规范性差、知识描述二义性、知识元利用率低等问题,这就造成了知识不能被油田开发技术人员高效利用的局面,引起知识信息泛滥。为了解决圈闭评价中知识形式化描述的问题,提出了基于本体的圈闭评价知识表示研究。从圈闭评价知识定义出发,将所研究的圈闭评价知识划分为基本实体、成果案例、方法规范、数据类知识四类。在确定知识定义和范畴后,结合圈闭评价知识特点,以及多种知识表示方法对比,最终得出基于本体表示法更适用于圈闭评价的知识描述。由此,将本体论思想引入圈闭评价知识表达中。提出圈闭评价知识本体TEKO的形式化定义并对其构建,采用OWL语言对圈闭评价知识本体TEKO进行表达和统一描述,最终形成基于本体的圈闭评价知识表示形式。便于圈闭评价知识的资源共享和知识重用,将其应用于建立圈闭评价知识库,为圈闭评价知识抽取、知识管理、知识检索等提供基础供应。The key process of trap evaluation in the risk prevention and feasibility evaluation of oil and gas exploration indicates that the oil field has an increasing demand for trap evaluation knowledge.However,when faced with the evaluation of many knowledge resources in traps,their knowledge presents problems such as poor knowledge representation,ambiguity in knowledge description,and low utilization of knowledge elements,which results in the situation that knowledge cannot be efficiently used by oilfield development technicians,causing the flood of knowledge and information.In order to solve the problem of formal knowledge description in trap evaluation,an ontology-based knowledge representation of trap evaluation is proposed.Starting from the definition of trap evaluation knowledge,the studied trap evaluation knowledge is divided into four categories:basic entities,result cases,method specifications and data knowledge.After determining the definition and category of knowledge,combining the characteristics of trap evaluation knowledge and the comparison of multiple knowledge representation methods,it is finally concluded that knowledge description based on ontology representation is more suitable for trap evaluation.As a result,the ontological idea is introduced into the expression of trap evaluation knowledge.The formal definition of the trap evaluation knowledge ontology TEKO is proposed and constructed,and the OWL language is used to express and uniformly describe the trap evaluation knowledge ontology TEKO,and finally form an ontology-based representation of the trap evaluation knowledge.It is convenient for the resource sharing and knowledge reuse of trap evaluation knowledge,and it is applied to establish a trap evaluation knowledge base to provide basic supply for trap evaluation knowledge extraction,knowledge management,and knowledge retrieval.
