在油气田开发中,从钻井、开采、集输、到油气水处理、储运等生产的各个环节腐蚀都无处不在,无时不有,生产安全、人身安全和环境保护都受到影响。腐蚀是制约和影响油田生产的主要因素之一。油田已开发多年,各类埋地管线问题也日趋突出,各类穿孔产生的经济损失和安全问题已威胁到油田的可持续发展,只有进一步查出管线腐蚀的原因,减缓管线各类穿孔的发生,延长使用其寿命,才可能十分有效地控制油田腐蚀。本文通过分析油田集输管线腐蚀的影响因素,介绍集输管线的防腐技术,使我们有能力采取及时有效措施进行预防和控制,尽量降低管线腐蚀程度,减少管线穿孔几率,延长管线的使用寿命,确保油田的正常生产和运行。
In the development of oil and gas fields, corrosion from every aspect of production such as drilling, mining, gathering and transportation, oil-gas water treatment, storage and transportation is ubiquitous and ever-present. Production safety, personal safety and environmental protection are all affected. Corrosion is one of the main factors restricting and affecting oilfield production. The oilfield has been developed for many years, and various buried pipeline problems have become increasingly prominent. The economic losses and safety problems caused by various types of perforation have threatened the sustainable development of the oilfield. Only by further detecting the causes of pipeline corrosion and reducing the occurrence of various perforations in the pipeline , To extend the use of its life, it may be very effective in controlling oil field corrosion. In this paper, by analyzing the factors that affect the corrosion of gathering and transportation pipelines in oilfields, we introduce the anticorrosive technologies of gathering and transporting pipelines, enable us to take timely and effective measures to prevent and control, minimize pipeline corrosion, reduce the probability of pipeline perforation and prolong the service life of pipeline, To ensure the normal production and operation of the oil field.
