基于本体的钻具组合智能设计

Intelligent Drilling Assembly Design Based on Ontology

为提高钻具组合设计过程中的设计知识利用率和设计效率,提出一种基于本体的钻具组合智能设计方法.该方法通过构建井眼参数、地层参数、模型知识以及钻井工程实例的本体模型,实现了对钻具组合设计知识的表示,构建钻具组合设计知识库,建立了本体间的语义映射关系,完成了对钻具组合设计知识的组织、推送和嵌入.最后,结合基于案例的推理方法,实现了对钻具组合的智能设计.

In order to improve the design knowledge utilization and design efficiency in drilling assembly design, an intelligent design method based on ontology is proposed in this study. The method realizes the representation of the design knowledge of the drilling assembly and constructs the knowledge base of the design of the drilling assembly by constructing ontology model including borehole parameters, formation parameters, model knowledge, and drilling engineering base. In the method, the semantic mapping relations among ontologies are built. Thus an intelligent drilling assembly design pattern was formed and the organization, push and embedding of design knowledge are realized.Combining the case-based reasoning method, the intelligent design of drilling assembly is realized.
