Abstract

The invention relates to the technical field of oil and gas pipeline repair, and discloses a knowledge graph construction method and system for oil and gas pipeline defect repair, which comprises thesteps of collecting related data of pipeline defect repair, performing arrangement and classification according to a pipeline defect repair process to form a preliminary pipeline defect repair data model framework, analyzing and disassembling the pipeline defect repair data model framework, determining a corresponding defect repair business data domain, determining a triple of pipeline defect repair knowledge, identifying the triad, completing knowledge extraction of pipeline defect repair, and importing the identified triad into a graph database to construct a knowledge graph. According to the method, existing pipeline repair implicit knowledge is explicit, pipeline repair business knowledge reference is provided for a user based on semantic search and semantic matching by means of visualgraph data and knowledge reasoning, a foundation is laid for accumulation, transmission and sharing of defect repair knowledge points, and the knowledge service is provided for the user in the defectrepair business activity, and meanwhile, the way of improving the user skills is expanded.

Description

technical field [0001] The invention belongs to the technical field of oil and gas pipeline repair, and in particular relates to a method and system for constructing a knowledge map for oil and gas pipeline defect repair. Background technique [0002] After many years of operation of oil and gas pipelines, due to corrosion, poor operation management and other reasons, various damages and leakages will inevitably occur, which will bring serious economic losses. long. The issue of how to restore the safe operation of pipelines cost-effectively and quickly has received great attention in the industry. After a safety accident occurs in oil and gas storage and transportation due to pipeline corrosion or other reasons, the repair of the accident is a passive response, while the repair of pipeline defects is to change from passive to active. Restoration maintenance plan, carry out planned repair, and this process is continuously improved periodically, so as to ensure that the pip...
