【摘要】：目前东北老管道安全环保废弃处置需求强烈,其中管内残留物的彻底清理极为重要,现有的清管器和化学清洗剂相结合的组合清洗技术国内尚无针对陆上废弃管道的应用先例,且缺乏可指导工程应用的施工工艺。根据管道组合清洗的基本原理,针对废弃管道的特点,提出了组合清洗技术的一般应用原则和施工工艺要求,对硬质原油蜡样开展化学清洗剂的模拟溶解效果测试,验证化学清洗剂的有效性。基于东北封存的老旧管道开展现场试验,验证组合清洗技术在废弃管段处置工程中的实际效果,从而促进实用的施工工艺的建立,为该技术在管道废弃处置中的推广应用奠定基础。研究表明:组合清洗技术能够实现管内残留物的高洁净度清理,可消除废弃管道的安全和环境风险,是陆上废弃管道处置过程中的重要保障技术。
[Abstract]:At present, there is a strong demand for the waste disposal of old pipelines in Northeast China, and it is very important to thoroughly clean up the residues in the pipes. The existing combined cleaning technology of pipe cleaner and chemical cleaning agent has no precedent for the application of waste pipeline on land in China, and lacks the construction technology to guide the engineering application, according to the basic principle of pipeline combination cleaning. According to the characteristics of waste pipeline, the general application principle and construction technology requirement of combined cleaning technology were put forward, and the simulated dissolution effect of chemical cleaning agent was tested on the wax sample of hard crude oil. To verify the effectiveness of chemical cleaning agent. Based on the old pipeline sealed in Northeast China, the field test was carried out to verify the actual effect of combined cleaning technology in the disposal project of waste pipe section, thus to promote the establishment of practical construction technology. The research shows that the combined cleaning technology can realize the high cleanliness of the residue in the pipe and eliminate the safety and environmental risk of the waste pipeline. It is an important safeguard technology in the process of disposal of waste pipeline on land.

【正文快照】： 目前,我国东北地区的许多管道服役时间已超过40年,老化问题突出,安全问题时有发生,油气管道的废弃不可避免。对于废弃的油气管道,如果选择直接拆除,由于管内残留介质和污染物的存在,会给管道的拆除带来困难,另外施工人员的误操作也可能会导致残留油气遇明火引发爆炸等巨大的安
