Laboratory drill rig for PDC bearing and cutter development
Oct 28th, 2009
Correlation of accelerated laboratory testing to actual field performance is essential in successful development of polycrystalline diamond cutters (PDCs) and diamond bearing elements for down-hole applications. A laboratory scale drill rig apparatus for the investigation of diamond bearing and drag bit cutter performance has recently been completed. The laboratory scale test rig is capable of producing rotary speeds from 40 to 1500 rpm, normal forces up to 165 kN, torque up to 1900 Nm, and rates of penetration up to 67 m/hr. Drilling tests to evaluate PDC cutters can be conducted using a controlled normal force or controlled rate of penetration. Test methods have been developed to enable accurate comparisons of PDC inserts to be made, typically in one day or less. PDC bit testing shows that we can clearly differentiate cutting efficiency and wear rates based upon changes in the material properties of the PDC inserts. The test rig can also be utilised to measure wear rates and frictional forces in diamond thrust bearings. Full scale PDC bearing experiments indicated that the bearings were capable of much higher loading than previously thought. Correlation between laboratory results and actual field performance will also be discussed. Article by J. Lund, C. Cooley, J. Gonzalez and T. Sexton.

Diamonds are not only "a girl's best friend." Soon they may be engineers' best friend too. US Synthetic Bearing takes advantage of its parent company's expertise with synthetic diamonds and applies that knowledge to radial thrust bearings to create a product that offers long life and low maintenance. Off-highway, oil and gas, and other industries benefit from these rugged bearings.

US Synthetic Bearings (USA, a division of Dover; NYSE: DOV) has launched the industry's first commercially viable lineup of radial bearings, based on synthetic diamond technology. Craig Cooley, US Synthetic Bearings Division General Manager, said: "Our radial bearings offer truly disruptive advances with longer life, reduced size, and increased lateral load-carrying capacity. A single installation can save many thousands of dollars in rig time."

US Synthetic Corporation (a provider of polycrystalline diamond cutters(PDCs) for oil and gas exploration) announced the availability of its radial bearing line that's based on synthetic diamond technology. Compared to tungsten-carbide technology, US Synthetic says its radial and thrust bearings extend bearing life by four to 10 times in the harshest real-world environments.
