Connection 5 1/2 FH Heavy Weight Drill Pipe 5 1/2 inch

Heavy weight drill pipe is well-suited for directional drilling applications. Because it bends easily, heavy weight drill pipe simplifies directional control and minimizes connection fatigue problems that are common in high-angle or horizontal drilling.For extended reach and horizontal wells, high-strength heavy weight drill pipe is often used high in the hole to apply weight on the bit. This is especially true for wells in which the total vertical depth to total measured depth ratio is low.

Product Description


Heavy Weight Drill Pipe 5 1/2 inch Connection 5 1/2 FH


Standard HWDP was developed to provide a gradual transition from heavy drill collars to relatively lightweight drill pipe.

 

This intermediate-weight pipe has a wall thickness of approximately 1 in. and helps prevent stress concentration at the top of the drill collar section. Heavy weight drill pipe also enables drilling at higher RPMs, reducing torque and differential pressure sticking.

 

Heavy weight drill pipe is well-suited for directional drilling applications. Because it bends easily, heavy weight drill pipe simplifies directional control and minimizes connection fatigue problems that are common in high-angle or horizontal drilling.

 

For extended reach and horizontal wells, high-strength heavy weight drill pipe is often used high in the hole to apply weight on the bit. This is especially true for wells in which the total vertical depth to total measured depth ratio is low.
