球形稳定器：球形稳定器结构短小紧凑、钻井阻力小，适用于打水平井及定向井。主要用于大斜度或水平井的钻井工程中，是控制井斜变化的重要工具。合理使用球形钻具稳定器，能有效地防止卡钻事故地发生，提高井深质量和钻井速度，降低钻井成本。SphericalStabilizerSphericalStabilizerisanimportanttooltocontrolholedeviationwhendrillingahorizontalwelloradeflectingwell.Thestabilizercanpreventfromstuckingindrillingandimprovethequalityofwellandspeedofdrilling,whichdecreasethecostofdrilling.Becauseof***allsize,simplestructure,itissoapplicableforhorizontalanddirectionalwell.Theguideinclinedplanecoveredwithpolycrystallinecompactandcuttingedgescoveredwithsphericaltungstencarbidestud,duringstabilizercontactswithroughedholewall,cancutorscrapedoffraisedorirregularwellwall,therefore,thesphericalstabilizersarewidelyusedinvariousofdrillingoperation.球形稳定器技术参数Specificati***andparametersofSphericalStablizer型号Type工作外径WorkingO.D.(in)本体外径BodyO.D.(mm)内径I.D(mm)长度Length(mm)连接螺纹Connection钻柱型String井底型Nearbit上端Top下端Down上端Top下端DownWQ1526″12151785NC38NC38NC383-1/2REGWQ1596-1/4″WQ1656-1/2″WQ1917-1/2″1595171850N***6NC50N***6NC50N***6NC504-1/2REGWQ2007-7/8″WQ2138-3/8″1655171850N***6NC50N***6NC50N***6NC504-1/2REGWQ2168-1/2″WQ2228-3/4″WQ2419-1/2″19771870NC50NC50NC504-1/2REGWQ2459-5/8″WQ2519-7/8″WQ31112-1/4″20371940NC56NC61NC56NC61NC56NC616-5/8REG7-5/8REGWQ44517-1/2″22824176940NC61NC61NC617-5/8REGWQ66026″6-5/8REG7-5/8REG6-5/8REG7-5/8REG6-5/8REG7-5/8REG)
