A closed-loop evaluation method and system for pipe body defects of long-distance oil and gas pipelines

Abstract

The invention relates to a closed-loop evaluation method and system for pipe body defects of long-distance oil and gas pipelines, and relates to the technical field of pipeline systems. The evaluation methods include: 1) start; 2) identification and evaluation of pipe defects; 3) review; 4) if it fails, it will return to the identification and evaluation of pipe defects; Review; 6) If it fails, it will be transferred back to the defect repair; if it is passed, it will be transferred to the database first, and the item elimination evaluation will be performed; 7) End. The invention can realize the closed-loop monitoring of pipe body defect identification and evaluation, defect repair to defect elimination item evaluation, simplify the operation process of defect closed-loop evaluation, integrate related business information, provide accurate and reliable data support for business management and decision-making, and effectively evaluate defect elimination item effect.

Description

Technical field [0001] The invention relates to a closed-loop assessment method and system for pipe body defects of long-distance oil and gas pipelines, and relates to the technical field of pipeline systems. Background technique [0002] With the development of pipeline construction, pipeline safety production has become an important part of pipeline operation and management. In order to achieve this goal, various pipeline safety management methods have been formed, of which integrity management with inspection and evaluation as the core is the most prominent. Integrity management first originated from abroad, and then recognized and developed rapidly in the field of domestic long-distance oil and gas pipelines. It takes risk evaluation and integrity evaluation technology as its core, and realizes it through technical means such as identification, evaluation, and repair of hidden risks. The pipe body is safe and extends the life of the pipe. [0003] Pipeline integrity managemen...

AI Technical Summary

Problems solved by technology

[0005] (1) The business correlation performance is weak, the workload is heavy, the business processing cycle is long, and the work efficiency is relatively low;

[0006] (2) Duplicated data entry and many manual data transfer links failed to provide reliable and accurate data support for business management;

[0007] (3) The degree of data integration in the entire defect life cycle is low, and the value of data cannot be fully utilized;

[0008] (4) The correlation between businesses is low, and the support for planning plans and project approval is insufficient;

[0009] (5) Lack of effective evaluation methods to assist pipeline managers to quickly and accurately grasp the effect of current pipeline defect management

[0010] To sum up, the existing management technology involves many related businesses and complex related relationships, which makes the operation complicated and takes up a lot of system resources, which is not conducive to the closed-loop evaluation of defects.

[0011] CN101173911A discloses a method for evaluating defects of long-distance oil and gas pipelines, CN2411484Y discloses a method for evaluating defects of long-distance oil and gas pipelines, and CN2731249Y discloses a method for evaluating defects of long-distance oil and gas pipelines, but none of them disclose defect repair and defect elimination item evaluation content, therefore, its evaluation method is not perfect
