中文摘要I井眼轨迹的三维显示摘要本文介绍了国内外井眼轨迹三维显示技术的研究现状，归纳了常规二维定向井轨道设计原则和几种轨道类型的计算方法，以及井眼轨迹测斜计算的相关规定、计算模型假设和轨迹计算方法。从井位、井下测量和计算三个方面对井眼轨迹误差进行了讨论并简要说明了不同的井眼轨迹控制。在此基础之上，利用VB和MATLAB软件编制了井眼轨迹的三维显示软件，并简要介绍了该软件的设计流程、主要功能和难点处理，指出了软件的不足之处，展示了井眼轨迹三维绘图的所有运行界面，并附上软件说明书。最后，对井眼轨迹三维显示开发的研究方向进行了展望。关键字井眼轨迹三维显示MATLABVisualBasic轨迹计算轨道设计误差分析重庆科技学院本科生毕业设计英文摘要IIAbstractInthispaper,athomeandabroadwelltrajectory3-Ddisplaytechnologyofthestatusquo，Summarizedtheconventionaltwo-dimensionaldirectionalwellthetrackdesignprinciplesandtrackseveraltypesofcalculationmethod，Andthewelltrajectoryinclinometertermsoftherelevantprovisions,themodelassumptionsandtrajectorycalculation.Fromthewells,undergroundmeasurementandcalculationofthethreeaspectsofthewelltrajectoryerrorwasdiscussedandabriefdescriptionofthedifferentwelltrajectorycontrol.Onthisbasis,usingVBandMATLABsoftwareproducedaholetrajectoryofthethree-dimensionaldisplaysoftware,andgaveabriefingonthesoftwaredesignprocess,anddifficultiesindealingwiththemainfunction,pointedouttheinadequacyofthesoftware,demonstratedthewelltrajectory3-Dgraphicsinterfacealltherunning,alongwithsoftwaremanuals.Finally,thewelltrajectory3-Ddisplaydevelopmentdirectionoftheprospect.Keyword:Welltrajectory；3-Ddisplay；MATLAB；VisualBasic；trajectorycalculation；trajectorydesign；ErrorAnalysis目录III目录摘要...................................................................................................................................IAbstract.........................................................................................................................II1绪论...............................................................................................................................11.1井眼轨迹三维显示技术产生的背景.................................................................11.2井眼轨迹三维显示技术国内外研究状况.........................................................11.2.1井眼轨迹三维显示技术国外研究状况[8]...............................................11.2.2井眼轨迹三维显示技术国内研究状况..................................................21.3本论文的主要研究内容....................................................................................32常规二维定向井轨道设计[11].......................................................................................42.1设计原则............................................................................................................42.2轨道类型及计算方法........................................................................................42.2.1三段式轨道.............................................................................................42.2.2多靶三段式.............................................................................................52.2.3五段式轨道.............................................................................................52.3井段计算设计结果表述....................................................................................53井眼轨迹测量及计算[10][11]...........................................................................................73.1基本概念..........................................................................................................73.2对井眼轨迹测斜计算数据的规定....................................................................73.3井眼轨迹计算的模型假设................................................................................83.4轨迹计算的方法................................................................................................93.4.1平均角法...............................................................................................103.4.2校正平均角法.......................................................................................113.4.3弦步法...................................................................................................124井眼轨迹误差分析[22].................................................................................................134.1误差原因分析..................................................................................................134.1.1井位的误差...........................................................................................134.1.2井下测量误差.......................................................................................134.1.3计算误差...............................................................................................144.2小结..................................................................................................................155井眼轨迹控制.............................................................................................................166井眼轨迹三维显示软件的编制[12]～[21].......................................................................176.1软件的功能简介..............................................................................................176.2软件的流程图..................................................................................................176.3软件窗体模块介绍..........................................................................................176.3.1用VB编制人机交互界面.....................................................................176.3.2用VB编制计算机绘图管理程序.........................................................176.4软件的难点处理...
