设备运维110|2023年08月GoldenGYRO在现场的应用崔自强(中海油田服务股份有限公司,天津300457)摘要:海上钻探的开发特点决定了每个区域需要设置规划的井位。随着调整井的开发和侧钻需要,井与井间如树的根系般错综复杂。井间最近距离仅在毫厘之间,彼此紧密靠近的套管本身具有磁性,它们和地磁场的相互作用使得传统的随钻测斜系统方位测量容易产生误差,导致轨迹偏差,后果严重的将引发井眼碰撞等事故。采用随钻陀螺测量,可实时作出风险预判,从而避免地磁场强度变化产生的磁干扰,从而得到准确的测量方位,用以开发井和调整井的初始定向和轨迹测量。文章以科学钻井公司的GoldenGYRO在现场中应用事例,讲述随钻陀螺在钻井勘探中的重要作业。关键词:随钻陀螺;测量过程;数据分析中图分类号:TE5文献标志码:A文章编号:1008-4800(2023)24-0110-03DOI:10.19900/j.cnki.ISSN1008-4800.2023.24.031FieldApplicationofGoldenGYROCUIZi-qiang(ChinaOilfieldServicesLimited,Tianjin300457,China)Abstract:Thedevelopmentcharacteristicsofoffshoredrillingdeterminetheneedforplannedwelllocationsineacharea.Withthedevelopmentofadjustmentwellsandtheneedforsidetracking,thewellsareasintricateastherootsofatree.Thenearestdistancebetweenwellsisonlymillicentimetres.Thecasingsclosetoeachotheraremagnetic.TheinteractionbetweenthemandtheEarth’smagneticfieldmakestheazimuthmeasurementofthetraditionalinclinometerwhiledrillingsystempronetoerrors,leadingtotrajectorydeviation,andseriousconsequenceswillleadtoaccidentssuchaswellborecollision.Theuseofgyrowhiledrillingcanmakereal-timeriskprediction,thusavoidingthemagneticinterferencecausedbythechangeofEarth’smagneticfieldintensity,soastoobtainaccuratemeasurementorientation,whichcanbeusedfortheinitialorientationandtrajectorymeasurementofdevelopmentwellsandadjustmentwells.ThisarticletakestheapplicationofGoldenGYROfromScientificDrillingInternationalasanexampletoillustratetheimportantoperationofdrillingwhiledrillinggyroscopesindrillingexploration.Keywords:whiledrillinggyroscope;measurementprocess;dataanalysis1采用随钻陀螺的目的和意义1.1常规陀螺定向的不足常规情况,多采用有线陀螺进行初始方位定向和轨迹测量作业,在确定初始方...
