Roller bits are mainly divided into two types:
i) Metal sealed roller bits
ii) Rubber sealed roller bits
Metal sealed roller bits main applications:
a) Adopted high-speed bearing metal sealed technology, long available time under the screw drilling condition.
b) High efficiency cutting edge and structure to improve drilling speed.
c) Cutter shell self-protection shape to reduce abrasion of ***ritus and unbreakable rock.
d) Best choice for directional well, horizontal drainhole and horizontal branch wells.
Rubber sealed roller bits main applications:
a) Adopted new alloy welding technology to improve abrasion and available time.
b) Multiple gauge structure, weld trimming teeth on the edge to enhance gauge protection ability.
c) High precision with radial sliding, two thrust rubber sealed bearing and optimized anti-seizure ability to avoid bits peel off. |
