提放式分瓣捞矛
提放式分瓣捞矛提放式可退大范围打捞矛,不但具有打捞范围大的特点,而且还具有通过下击,直接上提可以退出落鱼的优点,对于仅知道规格或一定内径范围的落鱼可以有效地打捞。在打捞作业中,有时对井下管状落鱼的内径尺寸了解的并不十分准确,而仅知道规格及一个大概范围,这样就要求打捞工具的打捞范围要大一些,以便能一次打捞成功。与普通的可退式打捞矛和提放式可退打捞矛相比,此打捞矛是一种性能优良、结构简单、操作容易、打捞范围大、抓捞和退出落鱼可靠的新型打捞工具。LiftingandLoweringSegmentSpearLiftingandLoweringSegmentSpearwhichisareleasablefishingtool,hasnotonlythecharacteristicsoflargescopeofsalvagebutalsotheadvantagesofreleasingfishesthroughdirectliftingaftershakingupanddown.Duringfishingoperation,weh***enoidealoftheexactsizeofthedownhole,withlittleinformationaboutgeneralspecifiactiontheSegmentSpearcanbeusedtoretrievethefallenobjects.Features:Comparedwithothernormalfishingtools,itisanew-typefishingtoolwhichcanretrieveandreleasefishes,hasperfectperformance,alargescopeofsalvage,andissimpleinstructure,safeandreliableinuse,easytooperate.主要技术参数Specificati***andparametersofLiftingandLoweringSegmentSpear型号Type外径O.D.mm(in)引锥直径O.D.ofguideconemm(in)打捞范围Fishingrange(mm)接头螺纹JointthreadTLM6086(33/8)48(17/8)46.1~50.7NC26TLM7395(33/4)52(21/16)54.6~62.0NC26TLM89105(41/8)58(21/4)66.1~77.8NC31TLM102127(5)75(3)84.8~99.1NC38TLM114127(5)85(33/8)92.5~102.3NC38TLM127159(61/4)95(33/4)101.6~115.0NC50TLM140159(61/4)102(41/32)117.7~127.7NC50TLM168159(61/4)135(53/8)140.3~155.3NC50TLM178159(61/4)144(59/16)149.8~163.8NC50TLM194159(61/4)160(65/16)168.3~179.7NC50TLM219159(61/4)180(71/16)190.0~205.7NC50TLM245203(8)210(81/4)215.9~228.665/8″REGTLM273203(8)210(81/4)241.3~260.365/8″REGTLM340203(8)210(81/4)298.4~323.865/8″REG)
