天然气集气系统工艺设计VIP专享VIP免费

摘要随着中国政府能源政策和能源结构的调整，以及大量气源的探明，天然气的开发和利用已成为不可逆转的大趋势，天然气开发、储存和应用技术已成为专门技术领域。集气系统是将来自采气井口的高压天然气，通过必要的处理工艺，使其气质符合商品气要求，压力、水露点满足外输条件，是天然气开采利用的重要环节，因此做好集气阶段的设计工作具有重要意义。天然气集气系统工艺设计一文共分四章，包括天然气储量和开发方案简介，升深2-1区块总体工艺选择和升深2-1区块集气处理工程等内容。以升深2-1区块为典型论述了该类型气田的开发特点，集气工艺选择，集气站布局及集气处理工程。目的是为了同类型气田的开发，集气站布局，集气处理等具体工艺的选择提供一个设计方案。关键词：天然气；系统；设计AbstractAlongwiththeChinesegovernmentenergypolicyandtheenergystructure'sadjustment,aswellastheprovedofmassivegassources,thenaturalgasdevelopmentandusehasbecomeairreversiblegeneraltrend.Thedevelopment,storageandappliedtechnologyofnaturalgashasbecomeaspecializedskilldomain.Throughtheessentialprocessingcraft,gasgatheringsystemsetsthehigh-pressurednaturalgascomesfromthegasrecoverywellheadtomeetthequalityrequirementsofcommoditygas,andsetsitspressure,dewpointofwatertomeettheconditionsoflosers.Itisanimportantlinkofgasexploitationanduse,thereforetomakethedesignworkofgasgatheringstagewellisofgreatsignificance.Thearticleofthenaturalgasgatheringsystemtechnologicaldesignisdividedintofourchapters,includingthesynopsisofgasreservesanddevelopmentprogram,theoverallcraftchoiceoftheSheng-shen2-1fieldandtheprocessingprojectofgasgatheringoftheSheng-shen2-1field.Takethesheng-shen2-1fieldasamodeltoelaboratethedevelopmentcharacteristicofthistypeofnaturalgasfield,thechoiceofgasgatheringcraft,thelayoutofgasgatheringstationandtheprocessingprojectofgasgatheringandsoon.Thegoalisforthesametypeofnaturalgasfielddevelopment,thelayoutofgasgatheringstation,gasgatheringprocessingandsoonconcretecraftchoicetoprovideadesignproposal.Keywords:Naturalgas;System;Design目录第1章概述........................................................11.1自然概况.................................................11.2本文研究的意义...........................................21.3主要研究内容.............................................3第2章天然气储量和开发方案简介......................................42.1天然气储量和气藏概述.....................................42.2开发方案简述.............................................42.3徐深气田开发特点.........................................5第3章升深2-1区块总体工艺选择.......................................63.1升深2-1区块的特点和总体工艺方案解决的问题...............63.2升深2-1区块外输气管道总体方案...........................73.3单井集气和多井集气工艺的选择.............................73.4集气站布局...............................................93.5采气管道防冻工艺选择....................................113.6集气站预处理工艺选择....................................123.7脱水工艺选择............................................133.8CO2腐蚀控制和监测方案...................................133.9采气井口设施和采气管道规划方案..........................16第4章升深2-1区块集气处理工程......................................244.1建设规模................................................244.2集气站..................................................244.3集气站总图布置..........................................274.4采气系统................................................284.5集气管...
