Embodiment Construction

[0083] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0084] The terms "first", "second", "third" and "fourth" in the description and claims of the present application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, for the terms "at least one", "plurality", "each" and "any one" used in this application, at least one refers to one, two or more, and a plurality refers to two or two More than one, while each refers to each of a corresponding plurality, and any refers to any one of a plurality. For example, the multiple security levels include 3 security levels, and each security level refers to each of the 3 security levels, and any security level refers to any one of the 3 security levels. It's the first, it can be the second...

Abstract

The invention provides a method and device for determining the safety level of a pipeline, computer equipment and a storage medium, and belongs to the technical field of oil and gas pipelines. The method comprises the following steps: acquiring multiple groups of pipeline parameters; constructing a test working condition according to each group of pipeline parameters, and determining the maximum failure probability corresponding to the plurality of test working conditions; dividing based on the maximum failure probability corresponding to the plurality of test conditions to obtain a plurality of failure probability ranges corresponding to the plurality of security levels; determining a consequence parameter range corresponding to each failure probability range as a consequence parameter range of the security level to which each failure probability range belongs; and determining the safety level of any pipeline based on the consequence parameter range corresponding to the safety level and the consequence parameter of any pipeline. According to the method, the quantitative standard of the safety level is defined, pipeline design, maintenance and construction can be effectively guided, the pipeline construction and maintenance cost is reduced on the basis of ensuring the safety and reliability of the pipeline, and the method has important guiding significance for pipeline construction and maintenance.

Description

technical field [0001] The present application relates to the technical field of oil and gas pipelines, and in particular, to a method, device, computer equipment and storage medium for determining the safety level of a pipeline. Background technique [0002] As the demand for energy continues to grow, so does the construction of oil and gas pipelines. Although the pipeline construction draws on various advanced technologies in the industry, such as the use of X90 steel grade pipelines, D1422mm diameter pipelines, and 0.8 design coefficients in the third-generation gas pipelines, how to ensure the safety and reliability of pipelines is an urgent need for the pipeline industry. solved problem. [0003] At present, pipeline construction is mainly carried out based on engineering practice experience, and the safety degree of the pipeline cannot be quantified. Therefore, a method that can quantify the safety level of the pipeline is urgently needed, and the determined safety le...
