As a tool for drilling rock formations, roller cone bits have been widely used. Significant improvements in drill bit performance have directly reduced drilling costs, especially the fastest progress in the past decade. Service life and drilling speed are two performance indicators, which ultimately determine the extent to which the drill bit affects the cost of drilling. Increasing the drill bit’s ROP and service life is an effective way to reduce drilling costs. Data has proven that the improvement of the ROP has a greater impact on the reduction of drilling costs than the improvement of the bit’s life. The improvement of the drill bit’s cutting structure is to improve the electric drill
’s machinery. The most direct method of drilling speed. For a long time, people’s improvements to the cutting structure have mainly focused on the main cutting tooth structure. For example, in the cemented carbide tooth structure, people have invented wedge-shaped teeth, spoon-shaped teeth, partial-top spoon-shaped teeth, etc. . In the past ten years, people have gradually realized that the gauge structure also has a greater impact on the electric drill bit’s ROP and life. Especially the drill bits used in highly deviated wells and horizontal wells require a reasonable gauge structure. Many new gauge structures have been It has been researched and developed and applied to roller cone bits with good results. 1 The use of high-strength and high-toughness alloy teeth improves the ability of the teeth to resist impact and reduces the probability of tooth breakage. The soft ground is inlaid with spoon-shaped teeth. The bearing of the 2 tooth palm is covered with a layer of hard alloy, and the roller bearing is silver-plated, so that the bearing has improved anti-seize and load-bearing capacity. The 3O-shaped sealing ring adopts more wear-resistant and highly saturated nitrile rubber, which enlarges the cross-section of the sealing ring, and adds a small sealing boss at the outer end of the sealing area, which improves the reliability of the sealing; 4 uses a steel ball locking tooth Wheels can be adapted to relatively high speeds. 5 uses newly produced grease that can withstand temperatures of 250 degrees Celsius and has low wear, which improves the high temperature resistance of the drill. 6 The optimized number of teeth and the equipment such as toothing and alloy teeth can maximize the cutting and speed of the drill.
Zhangjiagang ronix trading co. LTD have now make a decision to enlarge our company in other countries.
And finally, if you want to find additional resources for APPLICATION, simply go to Ronix Tools
Long gone are those days when electric drill
manufacturers were used to electric drill suppliers. Now new like electric drill manufacturers APPLICATION have come up.
Depending on the scale of the service, Zhangjiagang ronix trading co. LTD might also need to hire and manage an overseas workforce and comply with regulatory requirements.
