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.
