2023年第3期(总第9期)【技术探析】CNG地下储气井井筒倾斜弯曲模拟样管的研制王仁涛,史红兵,张海涛,万军(安徽省特种设备检测院,安徽合肥230051)摘要:为探究地下储气井井筒在倾斜、弯曲、变形等缺陷状况下安全使用状况,研究人员研发了一种地下储气井井筒倾斜弯曲模拟样管,样管能够用于地下储气井检测中套管腐蚀减薄后出现的弯曲变形等情况的研究、信号标定、检测装置的校准和复核,具有结构紧凑、制作方便等特点,井筒倾斜、弯曲、变形缺陷的样管还可模拟地应力、不同等级内部载荷和循环变化载荷作用下缺陷的发展状况和缺陷危险性。解决了缺乏储气井井筒倾斜、弯曲、变形缺陷的模拟检测用储气井样管的需求,并为储气井井筒倾斜、弯曲、变形缺陷后期评价标准的制定奠定研究基础。关键词:储气井;样管;倾斜;弯曲;缺陷DevelopmentofInclinationandBendingSampleTubeforCNGUndergroundGasStorageWellWANGRentao,SHIHongbing,ZHANGHaitao,WANGJun(AnhuiSpecialEquipmentInspectionInstitute,Hefei230051,Anhui,China)Abstract:Inordertoexplorethesafeuseofundergroundgasstoragewellshaftsunderdefectssuchasinclination,bending,anddeformation,asimulationsampletubeforinclinedbendingofundergroundgasstoragewellshaftshasbeendeveloped.Thesampletubecanbeusedforresearch,signalcalibration,calibration,andreviewofdetectiondevicesinthedetectionofbendingdeformationcausedbycasingcorrosionandthinninginundergroundgasstoragewells.Ithasthecharacteristicsofcompactstructureandconvenientproduction.Thesampletubewithdeformationdefectscanalsosimulatethedevelopmentstatusanddangerofdefectsundergroundstress,differentlevelsofinternalloads,andcyclicchangingloads.Itsolvedtheproblemofthelackofgasstoragewellsampletubesforsimulationdetectionofinclined,bent,anddeformeddefectsingasstoragewells,andlaidafoundationforthedevelopmentofpostevaluationstandardsforinclined,bent,anddeformeddefectsingasstoragewells.KeyWords:Gasstoragewell;Sampletube;Inclination;Bending;Defects收稿日期:2022-08-18基金项目:安徽省市场监督管理局科技计划项目(2019MK029、2020MK035、2019MK030、2021MK043)作者简介:王仁涛,男,安徽省特种设备检测院,工程师,硕士史红兵,男,安徽省特种设备检测院,高级工程师张海...
