Product Description

We sale PDC and Tri-cone bit

In the drilling process, the drill bit is the main tool for breaking the rock, and the wellbore is formed by the drill bit breaking the rock. The formation of a wellbore is good or bad, and the length of time it takes is not only related to the characteristics of the formation rock being drilled and the performance of the drill bit itself, but also related to the degree of mutual matching between the drill bit and the formation . The reasonable selection of the drill bit plays an important role in increasing the drilling speed and reducing the comprehensive cost of drilling. The drill bit is one of the important tools for oil drilling. Whether the drill bit adapts to the nature of the rock and its quality plays a very important role in the selection of drilling technology, especially in terms of drilling quality, drilling speed, and drilling cost. With a huge impact, PDC bit is a rock breaking tool widely used in the oil and gas exploration and development industry today. It effectively improves mechanical drilling tools and shortens the drilling cycle.

Cutting Structure

The wear-resistance of the teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for the steel tooth bit.The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit

Gauge Structure

Multiple gague protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone,tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capacity and bearing life.

Bearing Structure

High precision journal bearing with two thrust faces,Balls lock the cone.Hardfaced head bearing surface.Cone bearing inlaid with friction-reducing alloy and then silver-plated.Abrasion resistance and seizure of the bearing are improved.and suitable for high rotary speed

Seal and Lubrication

The advanced metal seal package consists of two metal seals and two elastic energizers.Compressed energizers ensure good contact being kept on two sealing surfaces of metal rings by elastic force,and achieves the bearing seal.In the drilling,metal seals are relatively dynamic,and the energizers are static.This will improve the reliability and durability of bearing seal.The pressure compensator system and advanced grease can greatly increase the lubricating reliability.
