The LL Type Reverse Circulation Junk Basket
The LL type reverse circulation junk basket is used to retrieve all types of small junk objects such as cone,cutter,hand tool and junks from the bottom hole.During drilling operation,it produces a local reverse circulation of fluid at well core so as to effect a complete recovery of junk in the junk basket .Especially when PDC bit is used ,cleaning bottom well by the tool becmes very necessary to ensure the bit with a normal application.The reverse circulation junk basket therefore becomes an essential tool in oil ,geology exploration and drilling engineering.
