Key seats develop during the drilling process whenever deviation or major changes in direction occur.Use SYMT Key Seat Wiper in these conditions will save you from costly fishing jobs and downtime.The key seat reaming tool is a sleeve with five bladees dressed with an agressive tungsten carbide hardfacing.
Operation and Application
SYMT Key Seat Wiper is made-up just above the top drill collar.It ocntains a sliding reamer sleeve with an O.D. slightly larger than the drill collar.When coming out of the hole.this sleeve detects the key seat first-instead of the drill collar-by becoming wedged in restricted place.
By releasing the drill pipe,the sleeve may be jarred out of the key seat.A clutch-drive on the bottom of the sleeve and the lower body is engaed by right-hand rotation.
Slowly raising the string and continuing rotation allows the sleeve to function as a reamer and wipe out the key seat.The operation may be repeated to further enlarge the area,thus permitting free passage of the collars.
Spiral blades with tungsten carbide hared-facing provide fast cutting action and maximum resistance to wear.
