【摘要】：稠油和高凝油等重质油占我国石油资源总量的25%-30%以上,重质油的开采地位及开采技术已备受关注。目前热力采油已成为在重质油占统治地位的方法。而油田注汽锅炉已成为重质油开采的核心设备。辽河油田是中国最大的稠油生产基地,稠油产量占总产量的60%以上。目前应用的注汽锅炉设备大部分是上世纪末的产品,设备的老化,性能的下降,达不到现今节能的要求。同时,注汽锅炉属于承压类特种设备,其运行的安全性也需要保障。因此,以节约成本、节能、节约材料为目的,开展油田注汽锅炉再制造技术研究具有重要的意义,也是保障辽河油田稳产的关键。本文在对注汽锅炉的结构和锅炉易损部位分析的基础上,开展了油田注汽锅炉的检测分析,应用理化分析方法,确定了材料破损位置及破坏根源。结合水质分析和过热分析,确定了锅炉易损部位的损坏原因。在此基础上,开展了注汽锅炉再制造工艺技术研究,形成了材料选取方法、焊接工艺、热处理工艺及防腐保温措施。应用再制造技术对10余台锅炉进行维修,并应用外观检测、无损检测及液压试验等检测方法,对再制造锅炉进行了评价分析,以确定其安全性和可靠性。
[Abstract]:Heavy oil and other heavy oils, such as heavy oil and high condensable oil, account for more than 25% to 30% of the total oil resources in China. The exploitation status and technology of heavy oil have been paid close attention to. At present, thermal oil production has become the dominant method in heavy oil production. The steam injection boiler has become the core equipment for heavy oil production. Liaohe Oilfield is the most important in China. A large heavy oil production base, Heavy oil production accounts for more than 60% of the total output. Most of the steam injection boiler equipment used at present is a product of the end of the last century. The aging of the equipment and the deterioration of its performance do not meet the requirements of energy saving today. At the same time, the steam injection boiler belongs to a special type of pressure equipment. Therefore, it is of great significance to study the remanufacturing technology of oil-field steam injection boiler for the purpose of saving cost, saving energy and saving materials. It is also the key to ensure stable production in Liaohe Oilfield. On the basis of analyzing the structure of steam injection boiler and the vulnerable parts of boiler, this paper carries out the detection and analysis of steam injection boiler in oil field, and applies the physical and chemical analysis method. According to the analysis of water quality and overheating, the causes of the damage of the vulnerable parts of the boiler are determined. On the basis of this, the remanufacturing technology of steam injection boiler is studied, and the material selection method is formed. Welding technology, heat treatment process and anticorrosion and heat preservation measures. More than 10 boilers were repaired by remanufacturing technology. The remanufacturing boilers were evaluated and analyzed by using the inspection methods of appearance inspection, nondestructive testing and hydraulic test. To determine its safety and reliability.
