转换接头 Cross-over Joint
转换接头转换接头在石油、***和地质钻井作业中起钻柱构件的转换连接作用,是连接上部钻具与下部钻具的主要工具之一,分钻柱转换接头和油管转换接头。A型(同径式)、B型(异径式)和C型(左旋式)。在钻井过程中,下部钻具的扣型与上部钻具的扣型连接不上,这就需要用转换接头来连接。Cross-overJointCrossoverjointactsforconversionandconnectionofdrillstemcomponentinpetroleum,naturalgasandgeologydrillingisusedmainlyforconnectingofupperdrilltoolsandlowerdrilltoolsduringdrillingoperati***.Itisdividedintodrillstringcrossoverjointandtubingcrossoverjoint.ThereareAtype(samediameter),Btype(differentdiameter)andCtype(levoform).钻柱转换接头技术参数SpecificationofDrillStringCross-overJoint名称Denotation上部连接件UpperConnectionPart下部连接件LowerConnectionPart型式Type方钻杆转换接头KellyCross-overJoint方钻杆Kelly钻杆接头DrillpipejointAorB钻杆转换接头DrillPipeJoint钻杆接头DrillPipeJoint钻杆接头DrillPipeJointAorB过渡转换接头CrossoverJoint方钻杆Kelly钻铤DrillCollarAorB钻铤转换接头DrillCollarJoint钻铤DrillCollar钻铤DrillCollarAorB钻头转换接头BitJoint钻铤DrillCollar钻头BitAorB水龙头转换接头SwivelJoint水龙头下接头SwivelLowerJoint方钻杆KellyC打捞用转换接头FishJoint方钻杆Kelly钻杆接头DrillPipeJointC钻杆接头DrillPipeJoint打捞工具FishingToolC油管转换接头技术参数SpecificationofTubingCross-Joint外螺纹ExternalThread内螺纹InternalThread螺纹代号ThreadCodeName锥度Tapering大端直径LargeEndDiameter(mm)小端直径***allEndDiameter(mm)内径I.D.(mm)螺纹代号ThreadCodeName锥度Tapering大端直径LargeEndDiameter(mm)小端直径***allEndDiameter(mm)内径I.D.(mm)1.900TBG1:1648.34740.31.900TBG1:1655.966.149.92-3/8TBG1:1660.35940.32-3/8TBG1:1673.058.161.92-7/8TBG1:167370622-7/8TBG1:1688.970.874.63-1/2TBG1:1688.986763-1/2TBG1:16108.086.790.54TBG1:16101.698884TBG1:16120.698.5103.24-1/2TBG1:16114.3111100.34-1/2TBG1:16132.1111.2115.94-1/2BCSG1:16114.71121001.900UPTBG1:1663.551.054.81.900UPTBG1:1653.25140.32-3/8UPTBG1:1677.862.867.52-3/8UPTBG1:1665.96450.32-7/8UPTBG1:1693.275.580.22-7/8UPTBG1:1678.676623-1/2UPTBG1:16114.392.296.93-1/2UPTBG1:1695.29275.94UPTBG1:16127.0104.9109.64UPTBG1:16108.010488.64-1/2UPTBG1:16141.3117.6122.34-1/2UPTBG1:16120.6117100.3)
