水力式外割刀WD-S型水力式外割刀是一种靠液压（循环钻井液）推动的切割工具，常与套铣管连接，专门用来从外向内切割各种类型的钻杆或油管。由于是水力进给，该割刀可在落鱼的任何一位置进行切割，边循环边切割，有利防卡套铣管，割断后与落鱼同时起出。它较机械式外割刀操作更简单，切割更平稳、快速、容易控制，是一种***可靠的切割工具。HydraulicExternalCutterHydraulicExternalCutterisakindofcuttingtoolwhichoftenconnectswithwashover,usingthepromotionofhydraulicpressuretocutdrillrod,casingandtubingofdifferentspecificati***fromoutsidetoinsidewhichAsresultofthepromotionofwaterpower,thecuttermaycutfishesinamoreflexiblewaywhilecirculating.Insuchacase,itishelpfulto***oidstuck,anditcanpullthefishesoutofthewellatthesametime.TheHydraulicExternalCutterissimpleinstructure,safeandreliableinuse,stablecutting,easytocontrol,highefficiencyperformance.Itisnotonlyabletocut***oothpipestring,butalsotocutitinexcessofjointinflexibleway.水力式外割刀技术参数SpecificationofHydraulicExternalCutter型号Type外径O.D.(mm)内径I.D.(mm)接头螺纹ConnectionAPI切割管外径O.D.ofCuttingPipe(mm)适用井径SuitableWellDiameter(in)WD-S95957323/8″TBG33.4、42.2、48.3、52.4111.13WD-S1031038123/8″TBG33.4、42.2、48.3、52.4、60.3120.65WD-S11311392NC2648.3、52.4、60.3、73.0130.18WD-S11911998NC2648.3、52.4、60.3、73.0136.53WD-S143143109NC3152.4、60.3、73.0、88.9158.75WD-S154154124NC3860.3、73.0、88.9、101.6168.28WD-S20320316565/8″REG88.9、101.6、114.0、127.0215.90WD-S21021017165/8″REG219.08)
