随着我国成品油和化工产品的消费量日益增大,原油的需求也随之增加。 中石化集团公司为了确保沿江中上游地区炼化企业原油的安全、稳定供应, 满足该地区成品油及石化产品市场需求,降低沿江炼化企业原油运输费用, 充分发挥仪征-长岭沿江原油管道运输能力,拟用日照-仪征原油管道将进 口原油与鲁宁线原油在仪征枢纽站中转外输。但现有仪长线仪征起点原设 计输量已经不能满足沿江中上游原油加工企业扩能的需要,因此新建仪长 复线是必要的,也是紧迫的。本文章拟研究建仪征-长岭原油管道复线黄梅 -荆门(岳阳)段,与前期规划建设的仪征-长岭原油管道复线仪征-九江段 共同组成仪征-长岭原油管道复线,为沿江中上游地区六家石化企业供给原 油。本文章通过对资源与市场分析,总体方案部署,管道敷设,管道用管 及经济评价几个方面的研究,解决新建管线如何满足荆门、长岭、巴陵三 家石化企业扩能对原油需求量增加的问题。通过不同增输方案的比选、优 化,初步确定增输工程的技术方案,测算工程的投资,进行技术经济指标 分析,从技术上、经济上评定该工程的可行性,为决策部门提供决策判断 依据。 关键词:输油管道,方案优选,敷设方式,财务评价,钢级 I Abstract With the increment of China's consumption of oil products and chemical products, crude oil demand increases. In order to ensure the safe, stable supply of crude oil in petroleum refineries in the upper reaches of Yangtze River, meet the region's refined oil and petrochemical products market demand, reduce the refinery crude oil transportation costs and give full play to the Yizheng _ Changling crude oil pipeline transportation capacity.,It is under onsiderating to use the Rizhao - Yizheng crude oil pipeline to transit and transport the import crude oil and crude oil in Luning line in Yizheng junction center.But the existing output in Yi - Chang crude oil pipeline can't meet the needs of the upstream crude oil processing enterprises in the expansion,so building a Yi _ Chang double pipeline is necessary, but also urgent. This article intends to build the Yizheng - Changling double pipeline Huangmei - Jingmen (Yueyang), together with the Yizheng - Jiujian pipeline which built early, composed of Yizheng - Changling crude oil double pipeline,which could supply oil for six petrochemical enterprises along the Yangtze River upstream. Through the analysis on the resource and market,overall plan disposition, pipe laying,pipeline choice and economic evaluation, this article is going to solve the problem of increase demand for crude oil which causes by expansion of ingmen, Changling, Baling Petrochemical Enterprises. In view of different expanding transmission, by means of schemes and optimization, we preliminarily determine the technological solutions on expanding transmission,then calculate engineering investment and analyse the technical economic index,and then evaluate the engineering feasibility in technology and economy,and finally provide decision-making basis for decision-making departments. Key words:pipeline for transportation of oil,program optimize, laying methods, financial evaluation, Sgrade of steel II 目录 第1章绪论 1 1.1研究背景 1 1.2研究的目的和范围 2 第2章资源与市场分析 4 2.1资源分析 4 2. 2市场分析 9 2. 3资源与市场平衡分析 13 2. 4资源与市场分析结论 15 第3章总体方案 17 3.1荆门原油供应方案 17 3. 2赤壁-荆门管道方案 28 3. 3赤壁-长岭-巴陵段设置外输栗方案 53 第4章管道敷设 56 4.1管道敷设方式 56 4. 2管道埋设深度 56 4. 3管沟底宽及坡度 56 4. 4管沟开挖与回填要求 57 4. 5管道转角 58 4. 6灾害性防护 58 4. 7管道施工困难地段 58 4. 8线路特殊地段施工 59 第5章管道用管 60 5.1钢管类型选择 60 5. 2钢种等级选择 60 第6章财务评价 67 6.1不确定性分析 67 6. 2经济评价结论 67 第7章研究结论 70 7.1主要研究结论 70 7. 2问题与建议 70 Wl m 72
