Method and system of closed loop assessment for pipe body defects of long-distance oil and gas pipeline

Abstract

The invention discloses a method and system of closed loop assessment for pipe body defects of a long-distance oil and gas pipeline, and relates to the technical field of pipeline systems. The assessment method comprises the following steps: 1) beginning; 2) recognizing and assessing the pipe body defects; 3) examining and verifying; 4) if the examination and verification are not pass, returning to recognize and assess the pipe body defects, and if the examination and verification pass, moving to a database firstly and then conducting defect repairing; 5) examining and verifying; 6) if the examination and verification are not pass, returning to defect repairing, and if the examination and verification pass, moving to the database firstly and conducting item-removing assessment; 7) finishing. According to the invention, a closed loop monitoring of defect recognizing and assessing, defect repairing and defect item-removing assessment for a pipe body can be achieved, the operation process of the defect closed loop assessment is simplified, related service information is integrated, accurate and reliable data support is provided for service management and decision, and defect item removing effect is effectively assessed.

Description

technical field [0001] 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. Background technique [0002] With the development of pipeline construction, pipeline safety production has become one of the important contents of pipeline operation management. In order to achieve this goal, various pipeline safety management methods have been formed, among which the integrity management centered on detection and evaluation is the most prominent. Integrity management first originated abroad, and was later recognized and developed rapidly in the field of domestic long-distance oil and gas pipelines. It takes risk assessment and integrity assessment technology as the core, and realizes The pipe body is safe and prolongs the life of the pipe. [0003] Pipeline integrity management includes six links: data collection, risk evaluation, integrity evaluati...

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
