API Thread Tricone Roller Drill Bits Used In Oil Drilling And Geological Drilling
Discriptions:
Tricone bit is the most widely used type of drilling bit. When the
roller bit is working, the cutting teeth alternately contact the
bottom of the well, the breaking torque is small, and the contact
area between the cutting tooth and the bottom of the hole is small,
which is higher than the pressure and easy to eat into the
formation. The total working length is relatively large, thereby
reducing the wear. Tricone bit can adapt to a variety of formations
from soft to hard.
Introduction:
According to the number of roller cone can be divided into single
cone bit, three roller cone bits and assembly of multi-cone bit.
According to the cutting material can be divided into steel teeth
(milling teeth) and indented roller cone bit.
As a tool for drilling rock formations, roller cone bits have been
widely used. Significant improvements in bit performance directly
reduce drilling costs, especially in the recent decade. Life
expectancy and penetration rate of two performance indicators, they
ultimately determine the extent of drilling costs impact drilling.
Increasing the penetration rate 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 rate has a greater impact on
reducing the drilling cost than the improvement of the drill bit
life, in which the improvement of the drill cutting structure is to
improve the drilling machine The most direct method of drilling
speed. For a long time, the improvement of the cutting structure
mainly focused on the main cutting tooth structure, for example, in
the cemented carbide tooth structure, people have invented wedge
teeth, spoon-shaped teeth, partial top spoon-shaped teeth, such as
wear gear and so on . It is gradually realized that the gauge
structure also has a great influence on the bit penetration rate
and life span of the bit. In particular, the bit used in high-grade
and horizontal wells requires a reasonable gauge structure. Many
new gauge structures have been developed Apply to the roller bit
has achieved good results.
From the bit manufacturers and research institutes in the tri-cone
bit holder structure research and application of dynamic can be
seen, it is gradually realized that the gauge structure on the bit
penetration rate and life have a greater impact, especially in the
application of directional drilling and horizontal well bit A
greater impact, research and development of the new gage structure
has been applied in the roller cone obtained good results. Drill
gauge structure from the passive gauge to the active gauge, gauge
material from low wear-resistant materials to high wear-resistant
composite materials, bit diameter and structure of the material
improvements greatly improved the performance of the drill to
further improve the bit ROP and life. At home and abroad, there is
a certain gap in the research on the structure and materials of the
protective gauze. The relevant domestic research institutes and
manufacturers of drill bits should further strengthen their
research on the structure and materials of the gauge guns. In
particular, they should pay more attention to the research and
application of some active gauge structures in the drill bit, Wheel
drill performance, to provide drilling users to adapt to new
drilling technology efficient drilling bit.
Drill bits are the most widely used in oil drilling and geological
drilling. Tricone bits have the effect of rocking, crushing and
shearing the formation rock during rotation. Therefore, the roller
cone bit can adapt to various soft, medium and hard formations.
Especially after the emergence of jet-type roller bits and
long-nozzle roller cone bits, the roller bit drilling speed is
greatly increased, which is a major revolution in the development
of roller cone bits. Tricone bit by tooth type can be divided into
milling teeth (steel teeth) roller bit, insert the tooth (carbide
roller gear set) roller bit; according to the number of roller cone
can be divided into single-cone bit, three teeth Drill bit and
assembly of multi-cone bit. The most widely used at home and
abroad, the most common is the tricone bit.
