Ball/Conical Jet Mill Shoe

The Ball/Conical Jet Mill Shoe is a highly efficient wellbore cleaning tool that uses a dual cleaning method of high-pressure jetting and mechanical crushing. It "pulverizes" and removes compacted debris while also providing deep cleaning of the inner wall of the tubing or casing. It is primarily used to clear scale, hard deposits, compacted debris, and other blockages from the inner wall of the tubing or casing to ensure a clear path and improve downhole operational efficiency. Unlike traditional mill shoes, this tool focuses on efficient cleaning rather than solely on milling bridge plugs, allowing it to restore the full inner diameter in the shortest time, which increases operational safety and reliability.

Product Features

Multi-Nozzle Jetting Design

·       Multiple high-pressure jet nozzles: Positioned on the surface of the mill shoe, they can spray directional fluid jets to rapidly break up and wash away blockages.

·       High-energy jetting: Cuts and strips away scale, effectively removing hard deposits and stubborn residue from the inner wall of the pipe string.

·       Jet-induced self-rotation with a mud motor: Ensures cleaning coverage with no dead spots.

Mechanical Milling + Hydraulic Flushing

·       Rotary milling action: Crushes hard blockages.

·       Simultaneous hydraulic jetting: Cleans debris and carries it out of the wellbore, preventing secondary deposition.

·       Adapts to complex downhole environments: Improves the cleaning effect on tubing or casing.

High-Efficiency, Low-Damage Design

·       Wear-resistant alloy materials: Enables stable operation in high-pressure, high-speed rotating environments.

·       No damage to pipe walls: Avoids the risk of pipe wall wear that can occur with traditional milling methods.

·       Compatible with multiple fluids: Can be used with oil-d fluids, foam, fresh water, and other operational fluids.
