Method and system for processing leakage behavior of natural gas long-distance pipeline based on digital twinning

Abstract

The embodiment of the invention discloses a method and system for processing leakage behaviors of a natural gas long-distance pipeline based on digital twinning, and relates to the technical field of safe operation of oil and gas pipelines. The method comprises the following steps: a data interaction platform obtains dynamic monitoring data and sends the data to a data engine and a virtual engine; the data interaction middle station also sends an instruction to the data engine, extracts data required by modeling analysis, and sends the extracted data to the virtual engine; the data engine obtains natural gas leakage state data and a conservative boundary, and the conservative boundary is imported into the virtual engine. And the virtual engine fuses various simulation models to perform analogue simulation based on the received various data, and various analysis results are obtained through data analysis. And an analysis result is fed back to the data interaction platform to be pushed to the user level. According to the embodiment of the invention, through unification of data formats and multi-model and multi-dimensional fusion analysis, the accuracy of an analysis result is ensured, and the requirement for accurate decision making of natural gas leakage behaviors in practical application is met.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of safe operation of oil and gas pipelines, and in particular to a method and system for processing leakage behavior of long-distance natural gas pipelines based on digital twins. Background technique [0002] In the technical field of safe operation of oil and gas pipelines, once a long-distance natural gas pipeline leaks, technicians need to respond in time, predict the development trend of the accident, formulate an emergency response plan, and take corresponding measures to reduce the scope of the accident and reduce the accident loss. [0003] In related technologies, after a long-distance natural gas pipeline leaks, the analysis and evaluation of typical leakage behavior is mainly based on the traditional analysis and evaluation model of “pipeline leakage—diffusion / fire / explosion—closing upstream and downstream valves—venting—end of leakage”. The independent system establishes...

As a result, in the complete accident handling process, the work of each department is separated

[0004] In the current industry 4.0 background, the traditional analysis and evaluation mode and the establishment of independent models make technicians only analyze pipeline leakage behavior in a single, static, and isolated manner. The same leakage behavior corresponds to multiple different models, and the analysis results obtained Too simplistic, decentralized, superficial, with low flexibility and accuracy, resulting in a low matching degree between the obtained decision-making plan and the real situation of leakage behavior, and the timeliness and pertinence of natural gas leakage behavior processing are not strong
