【摘要】：随着人类社会的快速发展对能源的需求越来越大,石油与天然气工业得到了飞速发展,管道输送成为石油与天然气生产过程中的重要环节,已成为石油工业的动脉。作为五大运输方式之一,管道运输带来便利的同时,管道的安全运行工作也凸显重要,石油天然气管道与公路、铁路、桥梁、河流、光缆、电缆的交叉点的施工也越来越多,安全风险是越来越大。管道在服役中,部分长时间处在腐朽环境当中,部分处在高压、高温或高湿的环境中,并且管道内部经常充满有毒、易燃、易爆、腐蚀等介质,处于自然环境中的管道易受到风化、酸雨等腐蚀作用,以及人为因素和外部载荷的影响,很容易造成各种各样的缺陷和损伤。一旦发生油气输送管道爆炸或泄漏,往往会发生中毒、爆炸或火灾等重大恶性事故。因此为了增加缺陷管道的使用年限,减少资源浪费,就必须对缺陷管道进行维修加固和补强。管道进行检测—评估—维修补强是保证管道完整性的一个有效的作业链,管道维修补强技术是保证管道完整性和延长管道使用寿命的重要手段,因此深入研究长输管道维修补强技术对于保障安全生产,延长管道使用寿命,节约资源,确保油气长输过程的安全等极具生产价值和意义。本文通过全面调研国内外管道维修补强技术发展现状和进展,分析了当前各类长输管道维修补强的技术和工艺,总结出各项维修补强技术的优缺点及工艺原理和关键技术等,结合长庆油田某采气项目部输气管道维修补强现状,采用文献调研和现场生产实践与矿场实验相结合的方法,总结出适应于长输管道的维修补强技术,以及施工工艺和生产规范,为指导生产提供依据。
[Abstract]:With the rapid development of human society, the oil and gas industry has been developing rapidly. Pipeline transportation has become an important link in the process of oil and gas production, and has become the artery of the oil industry. As one of the five major modes of transportation, pipeline transportation brings convenience, at the same time, the safe operation of pipelines also highlights the importance. The construction of oil and gas pipelines and roads, railways, bridges, rivers, optical cables and cables is also becoming more and more common. Security risks are increasing. The pipeline is in service for a long time in a decadent environment, part in a high pressure, high temperature or high humidity environment, and the pipeline is often filled with toxic, flammable, explosive, corrosive and other media. Pipelines in the natural environment are vulnerable to weathering acid rain and other corrosion factors as well as human factors and external loads which can easily cause various defects and damage. Once oil and gas pipeline explodes or leaks, poisoning, explosion or fire often occur. Therefore, in order to increase the service life of defective pipeline and reduce the waste of resources, it is necessary to repair and strengthen the defective pipeline. Pipeline inspection, evaluation and maintenance reinforcement is an effective working chain to ensure pipeline integrity. Pipeline maintenance and reinforcement technology is an important means to ensure pipeline integrity and prolong pipeline service life. Therefore, it is of great value and significance to study the maintenance and reinforcement technology of long-distance pipeline for ensuring the safety of production, prolonging the service life of pipeline, saving resources and ensuring the safety of long-distance oil and gas transportation process. Based on a comprehensive investigation of the current situation and progress of pipeline maintenance and reinforcement technology at home and abroad, this paper analyzes the current technology and technology of various long-distance pipeline maintenance and reinforcement, and summarizes the advantages and disadvantages of various maintenance and reinforcement techniques, as well as the technical principles and key technologies. Combined with the current situation of gas pipeline maintenance and reinforcement in a gas production project in Changqing Oilfield, the maintenance and reinforcement technology suitable for long distance transportation pipeline is summarized by means of literature investigation, field production practice and mine field experiment. As well as construction technology and production specifications, for the guidance of production to provide the basis.
