I摘要道沟区地处陕西境内,具体位置在延安市甘泉县以南,当地的地貌属于斜坡带，最近几年，该地区成为我国石油开采的重要位置，研究区主要产油层为石油开辟的一个重要区块是低渗透油层，因此针对该区域进行开发时，要采取科学的手段所以选取合适的装置进行注水开发很有必要，同时在开采前，要制定规范化的注水计划，根据水库的前级。全面了解地质特征。因此，研究区，沉积相分析和水库的精细地层划分和比较它是研究的特点和然后掌握贮存器的油和气体分配规则是必不可少的。本文是基于D-G区的长6，长7油层基为研究对象。首先，根据记录和芯体的数据，所述研究区域的地层特性被确定。储层特征，压力系统，贮库型，对石油储层的内部结构进行全面探查后，根据石油开采的规范化技术，例如，常规的油气工程方法和油藏数值模拟技术，研究领域主要发展技术证策论证演示油田开发，开发方法，开发层系统，以及井网系统的原理的（以及井网方向井网行式以及密度，行距的确定，以及间隔确定)，单井容量，每日注射容量，确保地层压力保持均衡等。文章最后，对油藏注水开发所运用的技术进行计算，根据生产经验和掌握的数据，制定关于研究区注水开发石油的合理规划。关键词：地层特征、井网系统设计、低渗透、储层特征IIABSTRACTABSTRACTD-GoilareaislocatedinthesouthofGanquanCounty,Yan'anCity,ShaanxiProvince.ItislocatedintheeasternpartofnorthernShaanxislopezone.Inrecentyears,ithasbecomeanimportantblockofYan'anOilField.AnimportantblockofZhangyuOilReservoirinthestudyareaislowpermeabilityreservoir,whichmustachievescientificandeffectivedevelopmenteffect.Therefore,thedeviceofwaterinjectiondevelopmentisparticularlyimportant.Inordertomakeareasonablewaterinjectiondevelopmentplan,wemustrelyonthefrontstageofthereservoir.Comprehensiveunderstandingofgeologicalcharacteristics.Therefore,itisindispensabletostudythecharacteristicsofsedimentaryfaciesanalysisandreservoirfinestratigraphicdivisionandcomparisoninthestudyareaandtomastertheoilandgasdistributionrulesofthereservoir.ThispaperisbasedonChang6andChang7reservoirbedsinD-Garea.Firstly,thestratigraphiccharacteristicsofthestudiedareaaredeterminedaccordingtothedataofthecoreandtherecords.Reservoircharacteristics,pressuresystem,reservoirtype,acomprehensiveunderstandingofthegeologicalcharacteristicsofitsreservoir.Then,accordingtothebasictheoryofreservoirdevelopment,suchasgeology,conventionaloilandgasengineeringmethodsandreservoirnumericalsimulationtechnology,themainresearchareasarethedevelopmentoftechnicalproofanddemonstration.Demonstratetheprincipleofoilfielddevelopment,developmentmethod,developmentlayersystemandwellpatternsystem(andwellpatterndirection,wellpatternanddensity,determinationofrowspacing,anddeterminationofinterval),singlewellcapacity,dailyinjectioncapacity,formationpressuremaintenancelevelandotherkeyissues.Finally,theimportanttechnicalparametersofreservoirwaterfloodingarecalculatedandcombinedwithalargenumberofproduction.Basedonthepracticaldata,thereasonabledeploymentplanofwaterinjectiondevelopmentinthestudyareaisputforward.Keywords:formationcharacteristics,wellpatternsystemdesign,lowpermeability,reservoircharacteristicsIII目录目录摘要.....................................................................................................................................................IABSTRACT.........................................................................................................................................II目录.....................................................................................................................
