●非旋转扶正器（FWZ型）：非旋转稳定器（橡胶套稳定器）是钻井作业中为保护井壁不受刮削而制作的专用工具。在钻井过程中非旋转稳定器依靠芯轴体传递扭矩，而橡胶扶正套与芯轴体是滑动配合，可以相对运动，因此扶正套只起支承井壁的作用。Non-RotaingStabilizernon-rotatingstabilizer(rubbersleevestabilizer)isaspecialtoolindrillingto***oidbladewearandwalldamage.Duringdrilling,stabilizertransfertorquebydependingonmandrelbody,butrubbersleeveisslidingcoordinationwhichcanbemovedrelatively,asaresult,thesleeveplaysaroleofsupportingofholewall.Thesleeveismadeofspecialelasticmaterialandfixedbyalatchclutchtopreventfromrotating.Wheninstalledinthedrillstring,theprotrudingpartofdrillpipecan’ttouchthecasing’sinwall,sothatreducingthechanceofcolliding,wearing,anddeformingaswellasprolongedthepiecingofdrillpipe’slife.非旋转扶正器技术参数Specificati***andparametersofNon-RotatingStabilizer型号Type套筒Sleeve本体Body总长OverallLength(mm)长度Length(mm)外径O.D.(in)叶片数量BladeQty水眼I.D.(mm)打捞直径FishingO.D.(mm)连接扣型ConnectionFWZ157(套管)3807″4441273-1/2IF1600FWZ220(套管)5009-5/8″711654-1/2IF2000FWZ255(套管)50010-3/4″711654-1/2IF2000FWZ313(套管)50013-3/8″711654-1/2IF2000FWZ31052312-1/4″762156-5/8REG2010FWZ40554316″762417-5/8REG2210FWZ43054317″762417-5/8REG2210FWZ55863522″762417-5/8REG2210FWZ71171528″5762417-5/8REG2210)
