集输管道的输送介质成分复杂,多种腐蚀机理并存,集输管网的腐蚀完整性管理一直困扰着企业管理者,制约着油气田企业完整性管理水平整体提高。西南油气田借助于先进的清管检测技术,对集输管道的腐蚀缺陷的检测、识别和管理形成了系统思路,在集输管道的腐蚀缺陷的完整性管理方面做了一些有益的探索。对于在役运营集输管道,在清管现场检测工作中检测出的缺陷及时进行高质量的修复;加大对集输管道阴极保护的检测,管道不宜长期处于＂欠保护＂或＂过保护＂状态运行;加强巡检,及时发现管道泄漏,杜绝事故发生。对于待建拟建新集输管道,强化防腐概念,在工程设计阶段就将腐蚀防护工作一并考虑;强化安全环保意识,注重防腐技术的应用效果。

As the gathering and transportation pipelines transmit medium of complex compositions and corrosion mechanisms are various, the corrosion integrity management for the transportation pipeline network has plagued the enterprise managers and seriously restricted the overall improvement of the integrity of the oil and gas enterprises＇ management level. In the southwest oil ＆ gas fields, advanced pigging detection technology has been applied for corrosion defect detection, identification and management of systems, and .9？ some useful explorations in the integrity of management of the gathering pipelines corrosion defects have been made. For the gathering pipelines in service, the defects detected by pigging should be timely repaired. The inspection of cathodic protection of the pipelines should be strengthened to prevent the pipelines from operating at either ＂insufficient protection＂ or ＂over protection＂ conditions. Field inspection should be performed to find the leaking in a timely manner so as to prevent leaking - related accidents. For the new gathering pipelines to be constructed, the corrosion protection and prevention should be considered in the engineering design. The environmental protection awareness should be enhanced and great attention should be paid to the application results of anti - corrosion technologies.
