The paper studies the knowledge structure of conversion between the production analysis and relational mode. It includes the standard description of the meta-concept. the fact of engineering, design rules, and production activities. The representation method of knowledge frame is used to represent production concept and fact, and the service is used to represent the normal scheme of engineering. The domain ontology describes the basic concepts and relations among them, and defines the mapping relationship between logical concept and relational mode on the basis of above discussion. Considering the fact which considers production information as middle knowledge, it achieves conversion between the production fact and relational mode. It designs the knowledge structure for oilfield development.%研究生产分析与关系模式相互转换的工程生产知识结构,包括领域元概念、工程事实、设计规则、生产活动的设计与规范化描述.采用框架表示法表达元概念及事实,以服务的方式定义工程作业的常规方案.引入本体描述工程基本概念与关联,完成逻辑概念与关系模式的映射.针对需要生产状态信息作为中间知识的事实进行工程生产-关系模式解读,给出油田开发知识服务设计.
