机械式内割刀ND-J型机械式内割刀是机械式切割套管、油管、钻杆的井下切割工具。它具有结构简单、工作可靠、操作方便、切割效果高等优点。为防止切割到套管、油管接箍，下入井内时割刀应避开接箍位置，有条件时可与接箍探寻器配套使用。可与打捞矛配合使用，将切割后的管柱随同割刀一次打捞出井，也可单独下打捞工具捞出被割下的落鱼。mechanicalinternalcutterThemechanicalinternalcutterisamechanicaltooltocutcasing,tubing,drillpipeinthedownhole.Inorderot***oidcuttingcoupling,thecuttershouldkeepawayfromthepositionofcoupling,andifallowedexplorershouldbeequippedtomakecuttingeasy.Itnotonlycancutatanypositionofthefishduringcuttingoperationindependently,butalsocanconnectedthereleasingspearaboveit.Aftercuttingisfinishedthepipestringabovecuttingpositionthecuttercanbeliftedoutatthesametime.Features:Themechanicalinternalcutterissimpleinstructure,safeandreliableinuse,convenientoperation,high-efficiencyperformance.Themechanicalinternalcutterc***istsofafrictionassemblywhichcansettheslipinsidertubularafterinitiation.Anindicatorsignalsthroughpumppressureandstabilizerslipkeepsthecutteranchoredinthecasing,whenthecutiscompleted.Thepist***aredesignedtoforcetheslipstofirmlyanchorthetoolbeforetheknivescontactingthecasing.机械式内割刀技术参数SpecificationofMechanicalInternalCutter型号Type外径O.D.(mm)接头螺纹ConnectionAPI切割管外径O.D.ofCuttingPipe(in)型号Type外径O.D.(mm)接头螺纹ConnectionAPI切割管外径O.D.ofCuttingPipe(in)ND-J6046CYZ22抽油杆Sockerrod23/8油管tubingND-J140112NC3151/2套管casingND-J73571.900TBG27/8油管tubingND-J168127NC3865/8套管casingND-J896723/8″TBG31/2油管tubingND-J168138NC3865/8套管casingND-J1028323/8″TBG4油管tubingND-J17814531/2″REG7套管casingND-J11485NC2641/2油管tubing41/2套管casing41/2钻杆Drillpipe5钻杆DrillpipeND-J21918551/2″FH85/8套管casingND-J24520065/8″REG95/8套管casingND-J29826065/8″REG113/4套管casingND-J34029565/8″REG133/8套管casingND-J127102NC315套管casing5钻杆DrillpipeND-J40637065/8″REG16套管casingND-J50847565/8″REG20套管casing)
