APPLICATION

YCPT's Non Rotating Protectors (NRP), improve drilling performance and completion efficiency by minimizing energy loss caused by wellbore friction, thereby optimizing energy delivery to the bit. They   can be aviable solution for challenging conditions encountered in deep directional wells; extended-reach wells; horizontal wells;   unplanned doglegs; deepwater riser operations; deepwater sub-salt wells; re-entries and sidetracks, shallow   kickoffs; production riser applications; slow, difficult drilling; deep S-shaped wells; underpowered top drives;   offset well heads; casing patches; and adverse ocean currents.

FEATURES AND BENEFITS

1. Positive protection against casing and riser wear during drilling operations.

2. The Significant torque reduction created by our fluid bearing design, with wear reduction around 20%, torque reduction around 30%. And field-proven for improved ROP.

3. Compatible with most oil, synthetic- and water-based drilling fluids, having excellent acid/ alkali   resistance.

4. The wear sleeve is adopted with enhanced PTFE material, with temperature resistance up to 200 ℃.

5. The high wear resistance enable more than 500 hours service time.

6. The product is simple structured, easy for onsite installation, directly mounting it on the drill pipe. Installation time: less than 1 minute.

7. On/off-site technical support and direction.

8. Reducing the torque of rotary-table by insulated support point that formed between   drill pipe and casing.

9. Protecting casing and reducing wearing of drill pipe and casing by drill pipe is insulated from the casing.

10. Reducing drilling resistance and also reducing friction between drill pipe and casing.
