Product Description

Product Description

The key seat reamer is a sleeve with five blades dressed with an aggressive tungsten carbide hardfacing. Key Seat Wipers are most effective for reaming out key seats when pulling out of the hole using the single-clutch ascent type, or using the double-clutch dual-action ascent-descent type when reaming in and out of the hole.

Running TIANHE key seat reamer will save you from costly fishing jobs and downtime.

OPERATION AND APPLICATION
The key seat reamer is placed in the string between the drill pipe and the drill collars. During drill ahead operations, the non-rotating sleeve will not ream the formation. In case of over-pull -- when tripping out drill collars or reaming back to shoe through a dogleg - rotate the drillstring while pulling out of hole to cause the clutch ring to transmit rotation to the wiper sleeve and initiate reaming operations.
The reamer blades will enlarge the key seat to allow the passage of the bottom hole assembly through potential tight sections of the hole.
When ordering please specify:

• Upper and lower neck diameter;
• Upper and lower connections;
• Circulation bore;
• Drill collar O.D. or gauge O.D. of wiper sleeve at blades
