一种新型绳索钻具打捞器

Introduction of a new type of wire grab

绳索钻具打捞器在地质勘探取心过程中有着相当重要的作用,不论是取心还是深孔投放钻具都要用到打捞器,这就要求打捞器在投放过程中有极高的可靠性,保证脱卡器能够顺利脱卡。同时打捞器在被提出钻外后要求有很高的安全性,保证不会空中脱钩伤人。本文所述的一种新型绳索打捞器具有较高的可靠性和安全性,并且兼具重锤的功能,无需打钻过程中投放重锤,可以大大提高钻探效率。

The wire grab has a very important role in geological exploration coring process, whether coring or run in, the ifshing device must be used, which requires the ifshing device has high reliability in running drilling tool process to ensure tripping device normally work. Meanwhile, the wire grab was presented in the drilling requires high security to ensure safety in production, and with a heavy hammer function, without dropping hammer in drilling process, drilling efifciency can be improved greatly.
