西部原油管道工艺方案优选黄志为摘要：我国国民经济的迅速发展，使得能源的需求大幅增加，特别是对具有“黑色黄金”之称的石油需求更是十分巨大，它是国民经济各个部门能够安全运行的血液，石油对我国经济安全稳定发展的作用是十分重要的。为了满足国民经济的发展和新疆原油外输的需要，国家决定投资建设一条大管径、大输量的输油管线，即：西部原油管线。本文主要工作是根据管线上下游的供需情况，进行管线初步设计工作，对管线建设前的工艺参数进行了分析和计算，并最终通过方案经济性效果分析确定最优的工程建设方案，该方案下的最优管径为914mm。并进行了首站站内工艺流程设计。关键字：西部原油管道初步设计输送工艺经济性比较OptimalchoiceofwesterncrudeoilpipelineprocessscenarioHuangzhiweiAbstract:Asthedevelopmentofthenationaleconomy,thedemandforenergyrisessharply,especiallyforcrudeoil,whichishonoredthenameof“blackgold”.Theenergyresourceofcrudeoilisthebloodofallthedifferentdepartmentsofthewholenationaleconomyanditisveryimportantforthesmoothlydevelopmentofthenationaleconomy.SothedepartmentdecisionmakerofthecountrydecidestoconstructalargediameterandhighthroughputcrudeoilpipelineinordertomeetthedemandoftheeconomydevelopmentandtheoutputoftheXinjiangcrudeoil.Accordingtotherealsituationofthesupplyofupstreamandthedemandofdownstream，thisarticlemainlyintroducesthecalculationandanalysisoftheprocessparameterbeforeconstructionanddotheinitialdesignoftheprojectandfinallyapplieseconomicanalysistotakethebestonefortheproject.Theoptimaldiameterforthisprogramis914mm.Anddesignthefirstoilpumpingstationprocess.Keywords:westerncrudepipeline；initialdesign；processscenario；economicanalysis目录引言....................................................................1第1章原油管道工艺设计...................................................21.1设计参数.............................................................21.2管道的纵断面图与水力坡降线...........................................21.3管材的选用...........................................................31.3.1钢管选用程序.....................................................31.3.2钢管选用设计原则.................................................41.3.3钢管管型的选择...................................................41.3.4钢管级别的选择...................................................5第2章基本设计参数.......................................................62.1基础数据.............................................................62.1.1物性参数.........................................................62.1.2管道沿线地温.....................................................72.2基础数据处理.........................................................72.2.1计算温度.........................................................82.2.2密度.............................................................82.2.3粘度.............................................................82.2.4计算流量.........................................................92.2.5计算管径.........................................................9第3章工艺计算..........................................................103.1具体计算............................................................103.2管材为X65时的设计方案..............................................143.3管材为X80时的设计方案..............................................15第4章投资计算..........................................................174.1选用X65管材的泵站建设费用........................
