集输处理罗睿乔等：海上气田群集输管网运行参数优化研究油气田地面工程https://yqtd.cbpt.cnki.net海上气田群集输管网运行参数优化研究罗睿乔孙旭向富明梁宁中海石油深海开发有限公司摘要：海上气田群集输管网由气井、海上平台、陆岸终端等单元组成，各单元之间由海底管道连接，既相互独立，又彼此影响。采用LedaFlow、K-Spice对气田群集输管网运行参数进行优化模拟，可以提升集输管网运行效率，降低系统能耗，实现增储上产、提质增效、节能降耗多重目的。模拟和现场测试结果表明，降低海底管线的运行压力，可以降低压缩机能耗，同时，还可降低海底管线上游平台的运行压力，进而降低生产井背压，增加技术可采储量。由此，总结形成一套可复制、易推广的海上气田群集输管网运行参数优化方案，具有很强的实际指导意义。关键词：海上气田群；集输管网；模拟优化；运行参数StudyonOperationParameterOptimizationofOffshoreGasFieldClusterGatheringandTransportationPipelineNetworkLUORuiqiao，SUNXu，XIANGFuming，LIANGNingDeepwaterDevelopmentCo.，Ltd.，CNOOCAbstract：Thepipelinenetworkofoffshoregasfieldsconsistsofgaswells，offshoreplatforms，on-shoreterminals，andotherunits.Eachunitisconnectedbysubseapipelines，whicharebothindepen-dentandmutuallyinfluential.UsingLedaFlowandK-Spicetooptimizeandsimulatetheoperationpa-rametersofthegatheringandtransportationpipelinenetworkofgasfieldscanimprovetheoperationef-ficiencyofthegatheringandtransportationpipelinenetwork，reducethesystemenergyconsumption，andachievemultiplepurposesofincreasingstorageandproduction，improvingqualityandefficiency，andsavingenergyandreducingconsumption.Simulationandfield-testingresultsshowthatreducingtheoperatingpressureofthesubseapipelinecanreducethecompressor'senergyconsumption.Italsocanreducetheoperatingpressureoftheupstreamplatformofthesubseapipeline，therebyreducingthebackpressureoftheproducingwellandincreasingthetechnicallyrecoverablereserves.Therefore，asetofreplicableandeasytopromoteoptimizationschemesfortheoperationparametersofoffshoregasfieldclustergatheringpipelinenetworkissummarizedandformed，whichhasstrongpracticalguidingsignifi-cance.Keywords：offshoregasfieldc...
