东北石油大学本科生毕业设计(论文)摘要油田既是产能大户,也是耗能大户。油田地面工程耗能在整个油田耗能中占有较大比例,而原油集输系统又是油田地面工程的主要耗能部分。目前国内外对高含水后期油气集输系统效率及能耗分析的研究报道比较少,因此,急需进行大量的工作弥补这方面的不足。本文依据大庆采油四厂杏十联地区原油集输系统冬季掺水加热期运行数据测试结果,对该地区原油集输系统各部分进行了效率及能耗计算。论文主要包括如下几部分:联合站效率及能耗计算、转油站效率及能耗计算、集输管网效率及能耗计算以及整个原油集输系统效率及能耗计算。在计算的基础上分析了集输系统各部分的用能状况,找出了该地区原油集输系统用能的薄弱环节,通过计算分析,该系统热耗占总能耗的95.76%,因此降低热耗是提高能量利用率的关键。转油站能量损耗占系统总能损的75.62%,是整个系统中能损最大的部分。提出了节能改造方案,并预测了该系统的节能潜力。预测经过节能改造后,该地区油气集输系统每年节电1.878×106kW·h,每年节气2.11×106m3,年节约能量8.61×107MJ。关键词:油气集输系统;效率;改造;能耗;计算东北石油大学本科生毕业设计(论文)AbstractTheoilfieldisalargeenergyproducer,aswellasalargeenergyconsumer.Theenergyconsumptionofoilfieldsurfaceengineeringisalargeproportionintheoilfield,andtheoilgasgatheringsystemisthemainenergyconsumptionoftheoilsurfaceengineering,theanalysisandreportsofhighcontainingwaterperiodoilgasgatheringsystemefficiencyandtheenergyconsumptioncomputationhomeandbroadisnotenough.Therefore,alotofworkisneededtomakeupforthisdeficiency.ThethesisisbasedontheresultofthehighcontainingwaterperiodoilgasgatheringsystemefficiencyandtheenergyconsumptioncomputationanalysisonDaqingNo.4OilProductionPlant.Andmakecomputationoneachsystem.Thethesisincludesthesectionsasfollowing:thecomputationofunionstationefficiency,thecomputationofOilTransferStation,thecomputationofpipelinenetworkefficiency,thecomputationofoilgasgatheringsystemefficiency.Makeananalysisoneachsystembasedonthecomputation,discoverstheweakpart.Throughthecomputation,theheatconsumptionis95.76%ofthetotalenergyconsumption.So,reducethermalenergyconsumptionisthemainwork;OilTransferStationenergylosscanbeaccountedfor75.62%ofthetotalsystem,it’sthelargestlossesofthesystem.Proposestheenergyconservationtransformationplan,predictstheenergy-savingofeachsystemandthegatheringsystem.Throughthetransformation,theenergy-savingofthegatheringsystemis1.878×106kW·hperyear;thegas-savingis2.11×106m3;theenergyconservationis8.61×107MJperyear.Keywords:Oilgasgatheringsystem;Efficiency;Transformationofenergyconservation;Energyconsumption;Computation东北石油大学本科生毕业设计(论文)目录第1章概述...................................................................................................................11.1研究目的意义...............................................11.2油田节能降耗技术现状.......................................11.3本文的主要工作.............................................5第2章油气集输系统流程简介.....................................................................................72.1转油站集输工艺流程.........................................72.2杏十联合站集输工艺流程......................................82.3杏十联地区原油集输系统工艺流程..............................8第3章集输系统效率及能耗计算模型.......................................................................103.1能量平衡分析模型..........................................103.2能量平衡原理..........................................
