GNSS静态观测技术在石油勘探坐标转换中的应用摘要:随着国家CGCS2000坐标系统的推广使用,我国石油行业存在巨大的坐标系统转换需求。以沁水盆地为例,基于已有国家控制点并新增部分控制点,构建了研究区GNSS控制网,再采用静态观测对各控制点进行两时段的连续观测,然后对观测数据进行处理与解算,求取研究区坐标转换参数,转换成果经过精度验核满足石油行业精度要求。实践表明,GNSS静态观测技术具有精度高、野外操作适应性强、成本较低的特点,适用于石油行业的坐标系统转换。关键词:GNSS;静态观测;坐标系统转换;沁水盆地中图分类号:P226+.3文献标志码:B文章编号:1672-4623(2023)03-0133-03ApplicationofGNSSStaticObservationTechnologyinCoordinateTransformationofPetroleumGeophysicalDataZHANGXuefeng1,HANShuxiang2,SHIXuefeng1,WANGYajun2(1.CNOOCEnerTech-Drilling&ProductionCo.,Ltd.,Tianjin300452,China;2.EquipmentServiceDepartment,EasternGeophysicalCompany,Zhuozhou072750,China)Abstract:WiththepromotionofthenationalCGCS2000coordinatesystem,thereisahugedemandforcoordinatesystemtransformationinourpetroleumindustry.WeusedexistingnationalcontrolpointsandaddingsomenewmoresinQinshuiBasintoconstructaGNSScontrolnetworkatfirst.Then,weobservedthecoordinatesofallcontrolpointsbystaticobservationmethodcontinuously.Finally,weprocessedandcalculatedtheobservationdata,andobtainedthecoordinatetransformationparametersofthestudyarea.Theresultsmettheaccuracyrequirementsofpetroleumindustryafteraccuracyverification.ThispracticeshowsthattheGNSSstaticobservationtechnologyhasthecharacteristicsofhighaccuracy,strongadaptabilitytofieldoperationsandlowcost,andisverysuitableforthepetroleumindustry’scoordinatesystemtransformation.Keywords:GNSS,staticobservation,coordinatesystemtransformation,QinshuiBasin收稿日期:2021-11-26;修回日期:2022-02-23。项目来源:中国海油青年科技与管理创新课题资助项目(JZTW2012KJ45)。第一作者简介:张雪峰(1979—),博士研究生,工程师,主要研究方向为油气地质勘探,E-mail:zhangxf12@cnooc.com.cn。引文格式:张雪峰,韩树祥,石雪峰,等.GNSS静态观测技术在石油勘探坐标转换中的应用[J].地理空间信息,2023,21(3):133-135.doi:10....
