The Tri-cone bit is the most widely used drill bit. When the tricone bit is working, the cutting teeth are in contact with the bottom of the hole, the rock breaking torque is small, the contact area between the cutting tooth and the bottom hole is small, the pressure is high, and it is easy to eat into the formation. The total working length is large and the wear is relatively reduced. The cone bit can accommodate a variety of strata from soft to hard.



Introduction:

According to the number of roller can be divided into single cone bit, three cone bit and assembly of multi-cone bit. According to the cutting material can be divided into steel teeth (milling) and insert tooth drill bit.

The tooling of the cone bit as a drilling tool has been widely used, and the significant improvement in drill performance directly reduces drilling costs, especially in the last few years. Life and drilling speed of two performance indicators, they finally determine the drill bit to affect the cost of drilling. Increasing the drilling speed and service life of the drill bit is an effective way to reduce the drilling cost. It is confirmed that the improvement of the drilling speed has a greater effect on the drilling cost than the drilling life. The improvement of the drill cutting structure is to improve the drilling machine The most straightforward method of drilling. For a long time, the improvement of the cutting structure has been mainly focused on the main cutting tooth structure. For example, in the case of cemented carbide structure, people have invented wedge teeth, spoon-shaped teeth, spatula, The It is gradually recognized that the diameter of the drill pipe also has a greater impact on the drilling speed and life of the drill bit, especially in the application of the drill string with high inclination and horizontal wells, and many new diameter structures are studied and developed. Applied to the cone bit to achieve a good effect.

From the drill bit manufacturers and research institutions in the three cone bit diameter track research and application of the dynamic application can be seen, people gradually realized that the diameter of the drill pipe drilling and life expectancy have a greater impact, especially in the directional wells and horizontal wells applied drill The impact of larger, research and development of new drill bit diameter structure in the application of cone bit has achieved good results. Drill diameter structure from the passive path to the development of active safety path, the diameter of the material from the low wear-resistant materials to the development of high wear-resistant composite materials, drill bit diameter structure and material improvements greatly improve the drill performance, and further improve the drill bit Mechanical penetration and life. At home and abroad in the diameter structure and material research has a certain gap, the domestic research institutions and manufacturers should further strengthen the diameter of the structure and materials research, with particular emphasis on the drill bit in the application of some active path management structure, to further improve the domestic teeth Wheel bit performance, for drilling users to adapt to the new drilling process of high efficiency drill bit.

Oil drilling and geological drilling is the most used or cone bit. The cone bit has the effect of rocking, crushing and shearing the formation rock in rotation, so the cone bit can accommodate soft, medium and hard layers. Especially in the jet-type cone bit and long nozzle after the emergence of cone bit, the cone drill bit drilling speed greatly improved, is the history of the development of cone bit a major revolution. The cone bit can be divided into tooth type (tooth) by tooth type. The cone bit of the tooth can be divided into single cone bit, three teeth Wheel bit and assembly of multi-cone bit. At home and abroad use the most, the most common is the three cone bit.



Typical products:

Three cone bit is an important tool for oil drilling, its work performance will directly affect the quality of drilling, drilling efficiency and drilling costs f1. Three cone bit design is based on practical experience, combined with the trial method, repeated design and calculation, and thus design accuracy is low, long cycle, it is difficult to improve the design quality, and each calculation can only design a drill, low efficiency. Therefore, the development of a set of three cone bit CAD system to achieve the three cone bit parametric drawing is very necessary. 1 system of the overall design of the three cone bit parametric drawing system using functional modular programming method, the entire system is divided into four functional modules: user interface management module, drill bit tooth structure design module, database management module, parametric drawing Module. User interface design, embedded in AutoCAD using VBA secondary development tools to achieve. Users through the user interface module input three cone bit design parameters, to achieve human-computer information exchange. The main function of the bit structure of the drill bit is to calculate the complex three cone bit design data according to the theory of the three cone bit design. The database management module is a database created by Access 2003 as a data table.


Product Usage:
Drilling, exploration, oil, drill bits, drilling accessories

product name:
215.9mm metal seal Roschen tooth three cone bit

Product number:
FJ517G




Features:

1. The use of floating bearing structure, floating components from high strength, high flexibility, high temperature resistance, high wear resistance characteristics of new materials, the surface of the solid lubricant treatment. Reduce the relative speed of the bearing while reducing the friction surface temperature rise, can effectively improve the high pressure or high speed drilling process conditions, bearing life and bearing reliability.

2. Using high-precision metal seal. The metal seal is sealed by a carefully designed metal seal ring as a bearing, and two highly elastic rubber energies are located in the palm and the seal area of ​​the teeth as a static seal, and the optimized seal compression ensures two A metal ring seal surface always maintains good contact.

3. Steel ball locking roller, to adapt to high speed.

4. The use of a rubber seal can limit the differential pressure and prevent the drilling fluid into the lubrication system, providing a good lubrication guarantee for the bearing system.

5. Rhithers. and Rhitheric polymersomenic polymers Results polymers Results polymers Results None Results Avg -

6. The drill bit is made of high strength and high toughness carbide teeth, optimized the number of teeth, the number of teeth, the height of the teeth and the unique alloy tooth profile, give full play to the high wear resistance and excellent cutting ability. The new wear-resistant material of the steel tooth bit welding and welding of the steel tooth bit improves the life of the drill bit while maintaining the high drilling speed of the steel drill bit.



Product advantages:

According to the number of teeth can be divided into single cone, double cone, three cone and multi-cone bit. At home and abroad use the most, the most common is the three cone bit. In the oil, ground and various drilling industry, the cone bit is an indispensable part, but the cone bit for some drilling industry price is too high, which prompted some drilling industry on the second-hand cone bit produced a great Interest, its low price, reliable quality (only 1/3 of its life in oil drilling), the drilling industry to reduce the large cost, so the second-hand cone has become part of the drilling industry, an important part.
