油气集输管是从油气井口到联合站间的输送管道,是各油气田用量较大的一种管材。长期以来,油气集输都采用钢制管材,但因为各油田所处地域和地下水矿化度不同,钢制管材也存在不同程度的腐蚀和结垢,尤其在含硫化物及氯离子高的地区,管线腐蚀十分严重,多则三五年,少则一两年,个别的甚至几个月就被腐蚀,出现穿孔刺漏。加之钢制集输管材需要大量的钢材,每炼1吨钢,不仅要消耗大量煤炭,还会排放大量的二氧化碳。
Oil and gas gathering and transportation pipe is the pipeline from the wellhead to the joint station, which is a kind of pipe material with large dosage of each oil and gas field. For a long time, steel pipes have been used for oil and gas gathering and transportation. However, due to the different salinities of ground and groundwater in the oilfields, there are also corrosion and scaling of steel pipes in different degrees, especially in areas with high sulfide and chloride ion Pipeline corrosion is very serious, as many as 35 years, as little as a year or two, some or even a few months was corroded, piercing punctures. Coupled with the steel gathering pipe needs a lot of steel, each refining 1 ton of steel, not only to consume a large amount of coal, but also emit large amounts of carbon dioxide.
