1.Metal sealed roller cone bit Metal seal bearing adopts metal seal ring, bearing is sliding bearing characteristics, this reasonable design concept, so that the metal sealed of roller cone bit service life is longer, of course, all kinds of oil fields, for the field of high requirements for the bit can use such a roller cone bit, but the price of roller cone bit is expensive. The bearing sealing system adopted in this series of drills has the characteristics of low linear velocity of bearing pair and low temperature rise of friction surface.The application of new synthetic grease improves the bearing's resistance to high temperature, wear and extreme pressure, and provides longer service life and higher reliability in vertical and directional Wells. 2.Rubber sealed roller cone bit Rubber sealed roller cone bit is adopted, bearing is rubber sealed bearing characteristics, this kind of bit and metal sealed roller cone bit usage is the same, but the service life of the bit is relatively short, of course, it also has its advantages, roller cone bit price is cheaper ; Rubber sealed rolling bearing bit is an ideal and economical tool for high speed drilling with low bit pressure.We can recommend a reasonable roller cone bit for your use according to the actual situation of the customer. Choosing the right roller cone bit/tricone bits can improve the drilling speed and service life.

The121/8" GS1615T PDC Bit made a record-breaking in Challenging in the section with several interbed Bit drills entire 1600-m section at average speed of 40m/hr Benefit Improved the ROP of drilling in the surface section with several interbed. Maximized bit life by staying sharper longer wile reducing balling in the soft formation and improving cuttings Double-row PDC bit technology helps bit the drilling day curve and reduce drilling costs by enhanced aggressive through out the bit run. Improving ROP,and drilling more efficiently. GREAT solution and results Completed the section in only 40 hrs The bit had no damage at all and drilled the coming well`s section from 1020-2003m An operator working in the FULONGQUAN in challenged GS1615T to drill the section with several interbed,and completed the1600m in only 40 hrs. When pulled from the hole ,the GS1615T PDC bit had no damage on the cutter structure at all. One GS1615T PDC Bit drilled the entire section(from500ft to 2100m),the vertical section,at an average speed of 40m/hr ,the efficiency Steer-ability saved 20- hours in the surface section. Well background challenges FULONGQUAN BLOCK The surface section with several hard interbed The operator need to complete the surface section in such a short time.
