Applicable industry classification. We need to understand it accordingly. Now some manufacturers’ new new composite slices can be applied to rock formations with tenth-level hardness. After the teeth are crushed and the rock is still eaten, the corresponding sliding and shearing of the rock occur at the same time. After heat treatment, drill holes on the drill bit body, press the synthetic polycrystalline diamond composite sheet into the drill bit body (tightly fit), and use columnar tungsten carbide to gauge the diameter.
The oil roller cone bit is a widely used drilling bit. Due to the changes in the mixing process and the manufacturing process, the quality performance of today's cutting teeth is much better, which greatly improves the erosion and impact resistance of the drill bit. At present, composite drill bits for oilfields are expensive and demanding among all composite drill bits.
When the oil roller bit is working,Round Shank Metal Drills Suppliers the cutting teeth alternately contact the bottom of the well, the rock breaking torque is small, the contact area between the cutting teeth and the bottom of the well is small, and the specific pressure is high. Since the domestic conventional gas is buried at 1,500 meters to 3,000 meters, there is not much gap with the shale gas burial.
As the degree of pollution intensifies, the human body will produce sub-health reactions and even threaten life stability. The rotating drill bit will rotate under the drive of machinery, which will drive the entire drill bit to produce centripetal motion, and crack the rock through encroachment and grinding.
This makes some indoor pollutants The concentration is several times higher than that outdoors. In view of the complexity of the formation in different regions and the diversification of drilling technology, drill bit manufacturers continue to optimize the bit design plan to speed up the bit 'transformation', extend the service life of the bit, increase the rate of penetration, and reduce the number of trips.
