Vigor Non-rotating Casing Brusher
Vigor Non-rotating casing brusher can be part of a complete wellbore cleaning tool string during the displacement process prior to running a completion. It can be rotated and reciprocated without damaging the casing or tool.
Rotation up to 150 rpm may be applied to create a turbulent flow and remove the cutting bed. The non-rotating stabilizers on the Tornar Brush provide a standoff and a generous flow area for fluid by-pass around the tool.
Description
China Vigor Drilling Oil Tools And Equipment Co., Ltd. is one of the most professional manufacturers and suppliers of vigor non-rotating casing brusher in China, featured by competitive price and fast delivery. Welcome to buy high quality vigor non-rotating casing brusher in stock here from our factory.
Vigor Non-rotating casing brusher consists of a one-piece Body, non-rotating Stabiliser and Brush assembly. The main mandrel rotates through the stabiliser and Brush assembly to avoid wear or damage to the casing during drill string rotation.
The Brush assembly is self-centralising inside the casing or liner to ensure equal cleaning at all well conditions. It's also rough, flexible and has the force needed remove and clean 360 degrees without rotation. The tool is suitable for HPHT wells and can withstand chemical or acid attack.

Advantages of Non-rotating Casing Brusher
✔ Cost Savings – Vigor Non-rotating casing brusher has incremental cost savings on logistics, deck space, inspection and maintenance and can also be serviced at the rig-site with basic hand tools.
✔ Increases Well Productivity – A properly executed wellbore clean-up reduces fine debris which can block screens and pore throats reducing well productivity.
✔ Integrity –Vigor Non-rotating casing brusher can be provided with any type of rig end connections including premium and high torque connections reducing the need for reduced strength crossovers. Single piece mandrel with no internal connections for increased strength.
✔ Reducing Non-Productive Time
✔ A robust wellbore clean-up is proven to reduce nonproductive time during the completion of the well
✔ Reduces premature failure of completion equipment by debris which can interfere with valves, electronics and other hardware

Application
- Pre-completion wellbore clean-up operations to remove hardened cement sheath, scale, mud solids, cuttings and other detritus from the casing wall
- Typically run as a complement to Vigor Non-rotating Casing Scraper for superior hole cleaning
- Drilling casing cement plugs in a single trip
- Extended reach wells where high strength drill pipe connections are required
- Remote locations where logistics are constrained and tool maintenance can be performed at the rig site
- Short tripping where multiple brush tools need to be run on the same string
