General corrosion management system for offshore oil and gas fields

Abstract

The invention belongs to the technical fields of risk management and asset integrity management and provides a general corrosion management system for offshore oil and gas fields. The system is composed of a management responsible personnel function module, a technical personnel function module, a corrosion specialist function module, a system administrator function module and a resource sharing and deciding platform. The system provides a more advanced management philosophy, takes the risk as the key point of the management and uses a level-to-level management, so that the management is more efficient; the asset integrity is taken as a management target, the purpose and the pertinence of the management are stronger; a management range, a management content and a management method are completely covered; all personnel related to the asset corrosion of the offshore oil and gas fields can participate and interact efficiently; and the integral level of the corrosion administrators is promoted by the sharing platform of the information resource. The system realizes the functions of corrosion monitoring management, corrosion pre-warming management, corrosion control management, failure analysis management and basic information management and has the advantages of strong practical applicability and popularization and application values.

Description

technical field [0001] The invention belongs to the technical field of oil field exploitation, and in particular relates to a comprehensive corrosion management system for offshore oil and gas fields. Background technique [0002] As an important form of marine economy, offshore oil and gas resources have become an important part of my country's energy supply. In the petroleum, petrochemical and chemical industries, the failure of almost all equipment and devices is related to corrosion, and the accidents caused by corrosion account for about 30% of the total accidents; due to the harsher environment of offshore oil fields, the corrosion of offshore oil production systems is higher than that on land. Far worse, 60% of repair costs are related to corrosion. [0003] Corrosion is a major potential risk faced by offshore oil and gas fields in the development process. Although domestic offshore oil and gas fields have carried out work and achieved certain results in corrosion m...
