在油气田生产建设过程中,管道输送油、气、水是目前油气田采用的主要输送方式而且大部分管道直接埋入地下管道埋地以后,由于土壤的物理和化学特性的不同.地理环境和气候条件的不同,管道虽然进行沥青防腐,但仍被严重腐蚀管道腐蚀产生的后果是十分严重的,一是由于更换管道造成的直接经济损失、二是因停工停产、跑漏油、气、水、污染环境等造成的间接经济损失,甚至还可能发生爆炸,引起火灾等恶性事故为保证油气田的正常生产、在不停工不停产、保证正常输送油、气、水的情况下,采用更换管道外壁防腐层的办法,对管道进行防腐
In the production and construction of oil and gas fields, pipeline transportation of oil, gas and water are the main transportation methods currently used in oil and gas fields and most of the pipelines are directly buried in underground pipelines due to differences in the physical and chemical characteristics of the soil Geographical and climatic conditions The pipeline corrosion is still severely corroded. The consequences of pipeline corrosion are very serious. The first is the direct economic loss caused by the replacement of pipes. The other is the shutdown of oil production, gas, water and pollution due to shutdown and shutdown. Environment and other indirect economic losses, and may even explode, causing fire and other serious accidents In order to ensure the normal production of oil and gas fields in the non-stop working without stopping to ensure the normal delivery of oil, gas, water, the use of replacement pipe wall coating Approach to pipeline corrosion
