新时期城市天然气利用项目的市场研究内容

2010294油气储运Oil&GasStorageandTransportationYouqiChuyun()..,2010,29(4):251254.:基于我国城市燃气阔步向以天然气为主导气源转变的现状,结合实际案例,介绍了新时期开发城市天然气利用项目的前期准备市场调研数据处理分析预测等环节需要研究的具体内容前期准备的主要目的是初步确定天然气利用的市场研究方向;市场调研则需要收集用气城市的政策信息,天然气用户的信息,以及用气城市燃气发展现状与竞争对手的信息;数据处理是指对用气负荷天然气价格及受众对价格的承受能力等的量化分析;分析预测即对用气市场进行客观全面理性地分析和判断,为合理利用天然气资源,发展天然气业务提供指导:城市气化;天然气利用;用气负荷;价格承受能力;市场研究,,,,,,()CNG(LNG),,,,,,,,,1前期准备,,,,,,,,,,,,;,,,;,50%,,,,;,,,90%,,,,,,,:,,1971,1994,:01082778553Email:[e-mail]2512010294谭静等:TanJing,etal:MarketResearchonDevelopmentandUtilizationofUrbanGasProjectsYouqiChuyun,[1]2市场调研,,2.1,,,,;,,2.2,,2.2.1居民和公福用户,,,,(),,,,,2.2.2采暖和制冷,,,,,,,,,[1]2.2.3CNG(LNG)汽车CNG(LNG),CNG,,,,CNG,CNG,,CNG:,CNG,,2.2.4市内工业,,,,,,:,,,,,,:,,,5000;,,1000,,,,2522010294油气储运Oil&GasStorageandTransportationYouqiChuyun,,,;,,,2.3,,,,,,,,,20045,,,,,,,,,,,,,3数据处理,,,3.1,,,,,,,,,,[2]3.2,,,,,,LPG15~20%,,,:,();,,,,[2],,,,,,,,,,,,,,,200931900/t,3.25/m3,:12%0.7%,,,!∀,(1)25MJ/kg,32.5MJ/m3,:+12%;+84%;+14%(0.1%,2%)2532010294谭静等:TanJing,etal:MarketResearchonDevelopmentandUtilizationofUrbanGasProjectsYouqiChuyun1/(#t-1)/(#GJ-1)/(#GJ-1)/(#GJ-1)19007685.1297.04139.84159.42100,,,,,,4分析预测,,,,,,,,,,,,,,,,,,,,!∀,,,,,:[1].[M].:,2007:125128.[2],.[M].:,2005:3839,8089.(:20090703)(上接第250页)[44],[D].:(),2006:6970.[45]WattersGZ.(Modern)AnalysisandControlofUnsteadyFlowinPipelines[M].1stedition.Boston:Butterworths,1979:13.[46]HUCK,PhillipsJW.PulsePropagationinFluidfilledElasticCurvedTubes[J].ASMEJournalofPressureVesselTechnology,1981,103(1):4349.[47]WiggertCD,HatfieldJF,StuckenbruckS.AnalysisofLiquidandStructuralTransientsbytheMethodofCharacteristics[J].ASMEJournalofFluidsEngineering,1987,109(2):161165.[48]BudnyDD,HatfieldFJ,WiggertDC.AnExperimentalStudyontheInfluenceofStructuralDampingonInternalFluidPressureDuringaTransientFlow[J].ASMEJournalofPressureVesselTechnology,1990,112(3):284290.[49]ZhangX,HuangS,WangY.TheFEMofFluidStructureInteractioninPipingPressureTransients[C].InProceedingsoftheFirstInternationalConferenceonFlowInteraction,HongKong,September,1994:532535.[50]SvingenB.AfrequencyDomainSolutionoftheCoupledHydromechanicalVibrationsinPipingSystemsbytheFiniteElementMethod[C].InProceedingsofthe17thIAHRSymposiumonHydraulicMachineryandCavitation,Beijing,China,September,1994,Vol.J:12591269.[51]OlsonLG,JamisonD.ApplicationofaGeneralPurposeFiniteElementMethodtoElasticPipesConveyingFluid[J].J.Fluids&Structures,1997,11(2):207222.[52]LavooijCS,TijsselingAS.FluidstructureInteractioninCompliantPipingSystems[C].Proceedingsof6thInt.ConferenceonPressureSurges,BHRA,1990:85100.[53]TijsselingAS.ExactSolutionofLinearHyperbolicFourequationSysteminAxialLiquidpipeVibration[J].JournalofFluidsandStructures,2003,18(2):179196.[54].[D].:,2000:3742.[55].[J].,2003,218(6):3142.(:20090916)254Vol.29No.42010油气储运Oil&GasStorageandTransportationYouqiChuyunOIL&GASSTORAGEANDTRANSPORTATION(MONTHLY)Vol.29No.4(TotalNo.256)Apr.25,2010ABSTRACTS#OVERVIEW#ZhengZhi,WangShuli,WuYuxian:DragLossofHydrateSlurryPipeliningandDragReductionTechnique,OGST,2010,29(4):241244.Frictionlossofhydrateslurryduringpipeliningisanalyzed.Throughmodelestablishing,relationshipsbetweenFanningfrictionfactorandcriticalReynoldsnumber,Hedstromnumberareobtained.Dragreductiontechniquessuitableforhydrateslurrytransmissionpipelinearepresented,suchasspiralflow,DRAadded,vibration,aerifying,fineparticle,waterinjection,stirring,threadinessmaterialandpipesectionvariation.Thesetechniquescanbeusedasreferencesinhydraulicdesignofhydrateslurrytransmissionpipeline,equipmentselectionandoperationmanagementofpipeline.SubjectHeadings:hydrateslurry,pipelinetransmission,frictionloss,prediction,dragreductiontechniqueLiMing,GongJing,LiQingping:LiquidsolidCouplingProbleminGasliquidTwophaseFlowPipelines,OGST,2010,29(4):245250,254.Thereciprocitybetweenunstableflowofgasliquidtwophaseflowandpipelinedistortionchangesthecharacteristicofaliquidpipelinesystemgreatlyandacceleratesaprocessinresearchofliquidsolidcouplingofagasliquidtwophaseflowpipeline.Thepapersummarizestheresearchsituationinliquidsolidcouplingofsinglephaseflowpipelinesathomeandabroad,andexpoundsitsresearchstressonruleofseverelyslagflowingasliquidtwophaseflowofoffshoreriseranditsliquidsolidcouplingproblem,andstatesacalculatingmethodforcommonlyusedvaluesinliquidsolidcouplingofflowpipelines.Also,issuesexistedinresearchofliquidsolidcouplingoftransientflowingasliquidtwophaseflowareanalyzedanditsdevelopingprospectaregiven.SubjectHeadings:gasliquidtwophaseflow,transientflow,pipeline,liquidsolidcoupling,severelyslagflow,researchsituationTanJing,WangXin,SunRui,etal:MarketResearchonDevelopmentandUtilizationofUrbanGasProjects,OGST,2010,29(4):251254.BasedonthesituationthatnaturalgasinChinaisrapidlychangingintoaleadinggasresourceofcitygas,combinedwithactualcases,marketresearchaboutdevelopingandutilizingcitygasinthenewperiodareintroduced,whichincludesprophasepreparationofgasproject,marketinvestigationandstudy,dataprocessingandanalysisand/orforecast,andamongthem,mainpurposeofprophasepreparationofgasprojectsistoinitiallydeterminemarketresearc
