可换套筒稳定器是石油、***及地质勘探钻井工程中，防止井斜变化的重要工具，在配备较大刚性的钻铤和施加较大钻压的使用情况下，合理使用稳定器，使井斜变化率和方位变化率较小，能避免产生“***”，并提高井深质量和钻井速度，降低钻井成本。通过更换扶正套，以适应不同井径，提高使用寿命。可换套筒稳定器由主体、稳定套、护套组成。稳定器工作表面的耐磨材料有四种：①表面镶嵌硬质合金柱；②表面镶嵌金刚石复合体；③表面低温钎焊硬质合金块；④表面堆焊耐磨焊条。ReplaceableSleeveStabilizerisanimportanttooltocontrolholedeviationinpetroleumandgasexplorationdrillingprocess.Inorderto***oidthe"hotdog"andh***etherateofchangeandlocationofthewelldeviationreduceduringdrilling,weshouldutilizethetoolwithreasonablewayunderthecaseequippedwithstrongdrillcollarandinflictedmorebiggerpressurewhichImprovingthequalityofthewellandthespeedofdrilling,reducingthecostofdrillingwell.Throughchangingsleevetosuitfordifferentboreholediameterstolengthenoperatinglife.Theadvantageisthatthesleevecanbechangedquicklyandeasilyaftersleevehardfacingiswornout.Thiskindofstabilizerisespeciallysuitableforworkingindirectionalwell.Therearefourkindsofabrasiveresistantmaterialsontheworkingsurfaceofstabilizer:inserttungstencarbidebutt***,insertdiamondcompoundbody,lowtemperatureweldingtungstencarbidepieces,hardfacingelectrodeonthesurfaceandsoon.SpecificationofReplaceableSleeveStabilizer型号Type钻铤直径DrillCollarO.D.(mm)扶正套StabilizerSleeve本体Body两端螺纹类型Connection长度Length(mm)工作外径WorkO.D(mm)加厚端直径UpsetEndO.D.(mm)加厚端长度UpsetEndLength(mm)打捞径长度FishingNeckLength(mm)水眼直径I.D(mm)上扣力矩Make-upTorque(KN.m)全长LOverLength(mm)钻柱型DrillStringType井底型NearBitType井底型NearBitType钻柱型StringType上端Top下端Down上端Top下端DownWH216165.1480214190200600716.95-7.251800-19001800-190041/2IF41/2IF41/2IF41/2REGWH210470210WH203472203WH197455197WH311203.2555310238769.7-111800-20001800-200065/8REG65/8REG65/8REG65/8REGWH305550305WH292540292WH279530279WH445228.668244427913.85-16.5575/8REG75/8REG75/8REG75/8REGWH432676432WH419670420WH406644407WH5592000-22002000-2200WH610WH660)
