Let us take a look at the characteristics of roller cone bits: For a long time, people’s improvements to the cutting structure have mainly focused on the main cutting tooth structure. Increasing the drilling speed and service life of the drill bit is the way to reduce the drilling cost. Especially the drill bit used in highly deviated wells and horizontal wells requires a reasonable gauge structure. The insert drill bit adopts high-strength and high-toughness cemented carbide teeth.
The steel ball locks the cone to adapt to high speed. The improvement of the drill bit cutting structure is to increase the drilling cost of the drill bit. Service life and drilling speed are two performance indicators, which determine the extent to which the drill bit affects the drilling cost in the later stage. However, the price of cone bits is too high for some drilling industries. The all-rubber oil storage bag that can limit the pressure difference and prevent the drilling fluid from entering the lubrication system provides a good lubrication guarantee for the bearing system. It has achieved good results when applied to roller cone bits. The optimized design of the number of teeth, the number of teeth, the height of the tooth and the special alloy tooth shape give full play to the high and excellent cutting ability of the insert drill bit.
Roller cone bit has been widely used as a tool for drilling rock formations. High-precision metal seals are used. The optimized seal compression ensures two The metal ring sealing surface always keeps good contact. When working, the cutting teeth alternately contact the bottom of the well,Custom Round Shank Metal Drill Suppliers the rock breaking torque is small, the contact area between the cutting teeth and the bottom of the well is small, the specific pressure is high, and it is easy to eat into the formation; the total length of the working edge is large, so the wear is relatively reduced.
The metal seal consists of a pair of designed and processed metal seal rings as the axial dynamic seal of the bearing. This has prompted some drilling industries to produce second-hand cone bits. The use of a new type of grease that can withstand high temperatures of 250°C and is resistant to wear. Significant improvements in drill bit performance have directly reduced drilling costs, especially in the past decade..
