本科毕业设计(论文)题目：蒸汽吞吐热力采油特征分析学生姓名：齐宝宝学号：08021163专业班级：石油工程专业0804班指导教师：蒋海岩2012年6月15日中国石油大学（华东）本科毕业设计（论文）摘要人们对石油的需求越来越多，但常规石油资源越来越少，稠油储量丰富。因此，人们更加关注对稠油的开采。本文根据稠油特征，选择蒸汽吞吐热力采油工艺技术，描述了蒸汽吞吐热力采油的工艺过程以及驱油机理，对蒸汽吞吐生产规律进行了理论预测与实际生产规律总结，描绘出典型的蒸汽吞吐井周期生产规律，同时对含边底水的油藏蒸汽吞吐生产规律做了部分描述。采油特征方面，主要对单井的单周期与多周期间的产油特征进行了总结；区块方面主要通过累产油与累注汽的关系以及注采方程的建立进行了描述。编写了计算机程序，实现了重要参数的计算，绘制了关键曲线，由此比较描述了蒸汽吞吐产油的特征以及对未来开采指数的预测。文中还对其它热力采油工艺技术进行了简要介绍。根据多口生产井以及区块生产资料，通过所编程序以及EXCEL进行实例计算，对未来生产进行较准确预测与指导。关键词：稠油；蒸汽吞吐；吞吐机理；生产特征；注采方程中国石油大学（华东）本科毕业设计（论文）ABSTRACTPeopledemandforoilismoreandmore,butconventionaloilresourcebecomeslessandless,whilereservesofheavyoilarerich.Therefore,peoplepaymoreattentiontotheminingofheavyoil.Accordingtothecharacteristicsofheavyoil,selectheatingsteamstimulationproductiontechnologytechnology,describestheheatrecoverysteamstimulationoftheprocessandoildisplacementmechanism,tosteamstimulationproductionruletheorypredictsandactualproductionrulesummary,andpaintthetypicalsteamstimulationwellproductioncyclerules,andtocontaintheedgeofbottomwaterreservoirsteamstimulationproductionrulesmadeapartdescription.Oilproductioncharacteristics,mainlytothesinglecycleofsinglewithmanyweeksduringtheperiodofoilproductioncharacteristicsaresummarized;Blockismainlythroughthetiredoilandtiredsteaminjectionandtherelationshipbetweentheestablishmentofinjection-productionequationisdescribed.Writeacomputerprogram,realizetheimportantparameters,paintedkeycurve,whichisdescribedinthecharacteristicsofsteamstimulationoffutureoilandminingindexforecasting.Thepaperalsotootherthermalproductiontechnologyisbrieflyintroduced.AccordingtotheproductionWellsshowsandblockproductionmaterial,throughtheprogrammingandEXCELexamplecalculation,thefutureproductionofmoreaccuratelypredictandguidance.Keywords:heavyoil;steamstimulation;oildisplacementmechanism;cumulativeoilproduced;oilfieldinfuseandpickequation.中国石油大学（华东）本科毕业设计（论文）目录第1章前言........................................................................................................................11.1研究的目的和意义..........................................................................................................11.2稠油的开采工艺..............................................................................................................11.3蒸汽吞吐以及动态预测方法..........................................................................................11.4研究主要内容..................................................................................................................2第2章蒸汽吞吐驱油机理与生产规律................................................................................32.1驱油机理..........................................................................................................................32.2蒸汽吞吐井生产规律......................................................................................................5第3章蒸汽吞吐单井周期采油特征..................................................................................113.1蒸汽吞吐单井单周期采油特征....................................................................................113.2水驱特征曲线预测单井蒸汽吞吐开采效果................................................................113.3蒸汽吞吐单井多周期采油特征....................................................................................12第4章开发单元产量递减规律..........................................................................................164.1累产油与累注汽关系曲线............................................................................................164.2累积汽油比与累积注汽量的关系曲线........................................................................194.3采收率确定方法............................................................................................................214.4蒸汽吞吐方程的建立与运用........................................................................................24第5章蒸汽吞吐生产特征应用..........................................................................................275.1程序编辑........................................................................................................................275.2程序流程图....................................................................................................................275.3程序界面........................................................................................................................275.4单周期产量递减分析....................................................................................................295.5水驱特征曲线预测单井开采效果................................................................................305.6多周期产量递减分析....................................................................................................325.7三参数法预测可采储量................................................................................................33第6章总结..............................................................................................................................35致谢......................................................................................................................................36参考文献..................................................................
