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

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.
