Trenchless Horizontal Directional Drilling
The segmented TCI (TCR) tapered reamer adopts a precisely engineered tapered structure to ensure fast and smooth drilling in trenchless applications and to achieve high-quality concentric reaming in a wide range of oil drilling applications. TCR HDD tools have been successful in both rotary and rotary-steerable assemblies in vertical and deviated wells.
Specifications
Our company can produce reamers of different sizes according to customer requirements.
Product Features
Our company produces various types of roller cone reamers, suitable for all models of trenchless and crossing drilling rigs and applicable to a wide variety of rock formations. Sizes range from 260 to 1800 mm. Their advantages include:
● Selection of the most suitable tooth type and bearing structure according to the rig characteristics and different formation conditions.
● Full coverage of the shirttail with cold-set wear-resistant alloy to reduce wear.
● Roller cone anti-detachment technology to prevent the cone from falling into the hole and causing downhole accidents after bearing damage.
● Hydraulic rock breaking. Smooth cuttings discharge, reducing rock cuttings accumulation.
● Guaranteed welding process to prevent overheating during welding.
● Guide spiral band design on the bit body for good guidance and cuttings control, reducing repeated re-grinding by the bit
