- 摘要:
- 针对任京输油管道正反输运行长期不清管的情况,通过比较现有结蜡模型的优缺点,建立了适用于大庆冀东混合原油的结蜡模型;考虑结蜡过程的周期性和时效性,研究了任京线的结蜡规律;利用两次任京线改线工程的现场实测结蜡厚度进行了验证,实测值与预测值的最大相对误差为15.8%;分析了任京线管壁蜡沉积物的基本物性和结构强度。研究成果为任京线安全清管提供了理论依据。
Aiming at forward and reverse transportation operation and longtime non-pigging conditions of Renqiu-Beijing oil pipeline and comparing the advantages and disadvantages of existing wax deposition models,the wax deposition model for Daqing-Jidong blending oil was established.Considering the periodicity and timeliness of the wax deposition process,wax deposition laws for Renqiu-Beijing oil pipeline under conditions of forward and reverse transportation operation and longtime non-pigging were studied.By means of measuring the site wax deposition thickness from two route alterations of Renqiu-Beijing oil pipeline,wax deposition laws were verified.The biggest relative error between actual measuring values and predicting values was 15.8%.Finally,the basic characteristics and structure strength of wax sediments on Renqiu-Beijing oil pipeline walls were analyzed.The research results provided the theoretical basis and technical support for the safe pigging of Renqiu-Beijing oil pipeline.2011,6(6): 7-11 收稿日期：2011-4-21分类号：TE832.35基金项目：中国石油天然气股份有限公司管道分公司2008年科技攻关项目“任京线输送大庆冀东原油优化方案研究”(编号20080102)作者简介：马伟平(1979-),男,山东惠民人,工程师,2004年硕士毕业于中国石油大学(华东)油气储运工程专业,现从事国内外油气管道标准研究工作.参考文献：
