LLF Type Reverse Circulation Junk Basket

    The LLF 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 bottom so as to effect a complete recovery of junk in the junk basket. Especially when PDC bit is used , cleaning well bottom by the tool becomes very necessary to ensure the bit with a normal application. The reverse circulation junk basket therefore becomes an essential tool in petroleum , geology exploration and drilling engineering.
