随钻打捞杯:在钻井过程中会发生各种落物事故，这种落物产生的原因一般有两种。一种是由井口掉进去的，例如各种钳牙、卡瓦牙、手工具及各种螺钉、螺母等。另一种是在井下钻进过程中产生的，如牙轮、弹子、***片、钻头巴掌等。无论产生何种落物，当影响钻静井时都必须进行打捞。这类打捞有两种不同方式，随着钻井的进行而同时机进行的随钻打捞为一种，专门的下钻打捞为一种。我厂生产的各种打捞杯，都具有足够的强度，可以承受钻井中的各种负荷而不损坏，同时可以完成上述两种打捞。在钻头上部接一个随钻打捞杯，在加上正常钻具。在钻井过程中，循环泥浆就可将一些细小落物，如吊钳牙、卡瓦牙及小螺钉、螺母等碎物冲进打捞杯的杯筒内。当起钻后即可捞获大量的小落物，这种方法非常有效和方便，既不需要进行专门的打捞而完成清洁井底的工作。另外，随钻打捞杯还可与磁力打捞器、反循环打捞蓝、反循环一把抓等打捞工具配合使用，进行专门的打捞作业。DrillingJunkSubTherearetwokindsoffishesinthecourseofdrillingwell.Oneisfallenfromwellhead,forinstance:tongkeys,slipdogs,handtoolsaswellasscrews,nutsetc.anotherisproducedinthecourseofdrillingwell,forinstancecones,pellets,cutterteethandhardmetalinsertsetc.Nomatterwhatfisheshappen,theyh***etobefishedupto***oidinfluencingdrillingwell.Therearetwowaysforfishing.Oneisdrillingwithfishingandanotherisspeciallyfishingwithfishingtools.TheDrillingJunkSubsproducedbyourcorporationh***eenoughstrengthtobearvariousloadsinthecourseofdrillingwithoutbeingdamagedwhileitcancarryouttwokindsoffishingasabove.JunkSubisconnectedtothetopofbitatdrillingandanumberof***allfishessuchastongkeys,slipdogsaswellasscrews,nutsetccanbeflushedintothesleeveofjunksubbycirculatingmud.Aftertrippingout,alargenumberof***allfishescanbecaughtandsothiswayisconvenientandefficient,thatistosay,cancleanupthebottomofwellwithoutneedingtofishspecially.Inaddition,JunkSubcanworktogetherwiththeoneofmagnet,reversecirculatingjunkbasketandjunkcatcheretcforspecialfishing.Features:JunkSubissimpleinstructurebutisgood,safeandreliableinuse.ThestructureofJunkSubismainlymadeupofbodyandsleeve.BodyandSleeveareconnectedbyscrewthreadsoastotakeupthecaughtjunkeasilyonthegroundandsleevecanbeeasilychangedafteritisdamagedsoastoprolongtheuselife.Sleevehas***allholesonitswalltoletmudflowthroughthemandsojunkscaneasilydropintothesleevefigure.随钻打捞杯技术参数SpecificationofDrillingJunkSub型号Type外径O.D.(mm)内径I.D.(mm)接头螺纹ConnectionAPI适用井径SuitableWellDiameter(mm)型号Type外径O.D.(mm)内径I.D.(mm)接头螺纹ConnectionAPI适用井径SuitableWellDiameter(mm)LB94941927/8″REG108.0-118.1LB1971977051/2″REG235.0-279.4LB1021023227/8″REG117.5-123.8LB2192197065/8″REG244.5-288.9LB1141143831/2″REG130.2-149.2LB2292297065/8″REG254.0-304.8LB1271273831/2″REG152.4-161.9LB2452457065/8″REG292.1-330.2LB1401403831/2″REG165.1-190.5LB2802808975/8″REG330.2-374.6LB1681685741/2″REG193.7-215.9LB3113118975/8″REG327-374.6LB1781785741/2″REG219.0-244.5LB32732710275/8″REG374.5-444.5LB1901905741/2″REG228.9-273.0LB34034010275/8″REG386.7-457.2)
