摘 要:研究支持关系数据库语义模型,引入领域主词关系网描述工程基本概念和关系,设计规范化描述与关联规则,完成工程逻辑概念与数据关系模式的映射。根据现有数据模型针对需要生产数据信息,在关系数据内部搭建关联模式,设计并建立语义解析推理机制。采用元词汇、工程事实及决策规则三层知识结构,将SQL操纵与主词关系网、关系数据库关联关系相结合,实现所描述的生产信息的获取与分析,给出相应油田动态开发数据解析结果。Semantic model is researched which supports relational database,introduces relation net of field subject which is used to describe basic conception and relation of project,designs standardization description as well as association rules and accomplishes the conception of project logic and the mapping of data relationship mode.In order to deal with various information of production data,association pattern is constructed in the interior of relational data and implemented reasoning mechanism of semantic analysis according to existing data model.It is to realize the perception and analysis of descriptive production information and to present the analytic result of development data of oil field behavior,which is based on three layer knowledge structure:meta vocabulary,project fact and decision rules.
