In fact, it is necessary for the craftsman to use the actual use to obtain a suitable actual environment. That effect can crush a part of the rock at the bottom of the well, and at the same time, the shear effect brought by the sliding of the cones cuts away the remaining between the teeth.
The teeth crush and eat into the rock, and at the same time, inevitable sliding occurs to shear the rock. The other part of the rock broke the rock at the bottom of the well and the well bore was extended. The steel ball locking roller is used, which can be suitable for relatively high speed. But in fact, as long as the oil roller cone bit is used properly, its service life can be prolonged, thereby saving costs for the construction unit.
If there is no problem with the equipment, you can check whether the drill bit is passivated by aluminum case hand tool set Manufacturers tripping. Especially after the emergence of jet oil roller cone bits and long nozzle oil roller cone bits, the drilling speed of oil roller cone bits has greatly improved, which is a serious revolution in the history of oil roller cone bits. The optimized number of teeth and the equipment such as tooth-exposure plus alloy teeth can make use of the cutting and speed of the drill to a large extent. Therefore, second-hand oil roller cone bits have become some An important sector in the drilling industry.
For the setting of the drill bit parameters in a general environment, a parameter table of the drilling speed and down speed of the produced drill bit is provided. The oil roller cone bits are used frequently and throughout. If the oil roller cone bit is continuously stuck or skipped during the drilling process, if there is no problem with the equipment, the drill should be pulled out to ensure that it will not continue to knock off the cone and make it scrapped.
