Ⅰ. The basic requirements of roller cone bit teeth
For the teeth of roller cone bits, the basic requirements are high rock breaking efficiency and long life. In order to meet this requirement, first, the geometric shape of the teeth must be reasonable; second, the material of the teeth must be wear-resistant and have sufficient strength.
Ⅱ. Common tooth types of roller cone bits
According to the type of teeth, roller cone bits can be divided into milling teeth (also called steel teeth) and cemented carbide teeth (referred to as inserts).
1. Milling tooth profile
The teeth of the milling cone bit are integrated with the cone shell. It is formed by milling the cone blank. In order to improve the wear resistance of the teeth, cemented carbide powder is applied on the tooth surface.
The tooth profile of milling teeth is mainly wedge-shaped teeth. The outer gauge gears can be made into P, T, and L shapes.
2. Insert tooth profile
a. Wedge-shaped teeth: suitable for crushing soft formations with high plasticity and medium-hard formations, with tooth tip angles ranging from 65 to 90 degrees, small tooth tip angles are suitable for soft formations, and large tooth tip angles are suitable for harder formations.
b. Scoop chisel: There is also a kind of wedge tooth with asymmetrical sides, one side of which is concave, called scoop chisel, suitable for drilling soft formations.
c. Conical tooth: There are two kinds of single cone and double cone. The rock is crushed by crushing method. The medium cone tooth of 60°-70° is used to drill medium and hard formations, such as limestone and dolomite. 90° cone and 120° double cone teeth are suitable for hard formations with high abrasiveness, such as hard sandstone and quartzite.
d. Triangular tooth: a plane is cut every 120° on the cone surface of the double cone tooth, which is suitable for the interlaced layer of hard and brittle stratum and soft and plastic stratum.

There are many manufacturers of tooth bits, and these drill bit factories provide bits of various types and structures. In order to facilitate the selection and use of roller cone bits, the International Association of Drilling Contractors (IADC) has developed a unified worldwide classification standard and numbering method for roller cone bits.
IADC stipulates that each type of drill bit is represented by three digits, and the meaning of each number is as follows:
The first digit indicates the type of tooth and the formation suitable for drilling:
1 – Milling teeth, soft ground;
2 – Tooth milling, medium to medium hard formation;
3 – Milling teeth, hard, abrasive or semi-abrasive formations;
4 – Spare;
5 – Insert teeth, soft to medium stratum;
6 – Insert teeth, medium-hard stratum;
7 – Insert teeth, hard, abrasive or semi-abrasive formation;
The second digit indicates that the drilled formation is subdivided into four hardness grades 1, 2, 3, and 4.
The third digit indicates the structural characteristics of the drill:
1 – Unsealed rolling bearings;
2 – T-shaped outer row tooth gauge;
3 – There are insert teeth on the gauge diameter;
4 – Sealed rolling bearing;
5 – Sealed rolling bearing, with insert teeth on the gauge diameter;
6 – Sealed sliding bearing;
7 – Sealed sliding bearing, with insert teeth on the gauge diameter;
8 – Directional well deflection bit;
9 – Other.
Advantages of roller cone bits:

In the process of drilling, china tungsten carbide drill bits is the main tool to break rock, and borehole is formed bya drill bit breaking rock. The formation of a well is good or bad, and the length of time it takes is not only related to the rock characteristics of the drilled formation and the performance of the bit itself, but also related to the matching degree between the bit and the formation. The reasonable selection of bit plays an important role in improving the drilling speed and reducing the comprehensive cost of drilling.
The bit is one of the important tools for oil drilling. Whether the bit adapts to the rock property and its quality plays a very important role in the selection of drilling technology, especially in the aspects of drilling quality, drilling speed and drilling cost. PDC bit is a rock breaking tool widely used in the oil and gas exploration and development industry today which effectively improves the mechanical drilling tools and shortens the drilling cycle.
Bit is one of the main drilling equipment. According to the different working environment and regional environment, the specification and shape of bit should also be different. When drilling oil, the bit should be selected reasonably and scientifically based on the specific needs and design scheme.
At present, there are many kinds of bits used in the petroleum industry. According to different drilling methods, the bits can be classified into diamond bits, roller bits and scraper bits. These three kinds of bits are the most basic ones.
Because of the excellent cutting performance of diamond drill bits rock, the diamond bit can drill at high speed and enlarge the drilling depth to a certain extent when being selected as oil drilling tool. In the process of drilling oil with diamond bit, the following aspects need to be paid attention to:
First, the price of diamond bit is relatively high, so we should operate it carefully to reduce the damage degree;
Secondly, the diamond bit has some defects in thermal stability, so the cooling performance and cleaning condition of the bit should be guaranteed when it is used;
Thirdly, its texture is relatively brittle, so the impact resistance of the diamond bit will be relatively poor, so we should strictly follow the relevant rules of the diamond bit to carry out strict and standardized operation.
When selecting a bit as an oil drilling tool, it is necessary to select the bit according to the actual situation of the drilling equipment, the actual conditions of the formation, the geological data of the adjacent oil wells and the formation data. During the selection, the following issues need to be considered:
First of all, we need consider whether there is soft and hard interlacing in the drilling formation;
Secondly, it should consider whether anti deviation drilling and curve operation are needed in the oil drilling work;
Thirdly, the actual depth of different drilling sections in the same well should be considered;
Finally, drilling geology, formation abradability and hardness should be considered.
Well drilling is the engineering of exploringand utilizing water resources in strata by using water well drill bits and technology. Groundwater is water that exists in cracks of the earth’s crust or in gaps in the soil. The various states of water buried below the surface are collectively referred to as groundwater.
How Water Cut Characteristics of Well Structures Influence the Well Yield: Clean Sand and Gravel Sedimentary Rock Clean sand and gravel sedimentary rock is the best source of water. This kind of structure has strong water absorption, high water content and good water permeability
The Mixed Layer of Sand and Gravel The sand and gravel mixture is also a water-yielding structure. Because of the different proportions of sand, it is a secondary water-producing rock. The lower the sand content, the higher the water yield.
Clay Structure Although the clay structure holds water well, it is difficult for water to move through it. This means that the clay structure does not flood the well, so it is not an aquifer.
The Sandstone It refers to the terrigenous clastic rocks whose grain size is 0.0625 ~2 mm and the sand accounts for more than 50% of all clastic particles. If the clay acts as a cement in sandstone to hold the sand together, then it is a poor water-yielding rock.
Limestone It is an excellent source of water in all sedimentary rocks. Limestone usually has large openings, such as underground karst caves that contain high water content but poor water quality.
Basalt In the earlier time, its beds are dense rather, so it is rather than a good water-yielding because they are tightly packed together. If it’s in later time,and it has spongy development, then it’s a good source of water.
Hard rock Such rocks as granite, porphyry, and other crystalline rocks are usually poor water producers. The worst water-yielding are metamorphic rocks such as gneiss schist, quartzite, SLATE, and soapstone.
In order to avoid the low efficiency of well drilling, the oil standard Tricone bit specification should be adopted in the design of the well drilling diameter. The selection of leading hole standard cone bit must be beneficial to the processing of reaming assembly cone bit in order to reduce the processing cost of bit. The effect of drilling parameters on drilling efficiency is weight on bit.

The Selection of Water Well Drill Bits The weight of the water well drill bits should be determined according to the formation’s hardness and softness. Meanwhile, the quality of water well bit, well bore, drilling tool, displacement, and performance of flushing fluid, equipment and power should also be considered.
The Uses of Water Well Drill Bits When choosing the tricone water well bit, you sho select the Tricone bit type to suit lithology requirements as much as possible, match bit size with drilling design, and use in order of size. In the process of using the water well drill bits, if the phenomenon of rampage occurs, the reasons should be analyzed immediately to check whether the formation changes or the borehole wall collapses. The parameters should also be analyzed and adjusted immediately. If the up-lift bit can’t be drilled normally, the up-lift bit should be checked.
The regular analysis of the working conditions of the water well drill bits in the hole is also important for the maintenance of the drill bit. In addition, measures should be taken to control well deviation, reduce the clearance between drilling tools and drilling holes, and play the role of full hole drilling and rigid anti-deviation.
In order to prevent deviation, centralizer and drill collar can be added on the top of the tricone bit.
GREAT can customize bigger diameter Hole openers for tunneling, such as subway, gas pipeline construction.
Characteristics of tunnel engineering:
The whole project is buried underground, so engineering geology and hydrogeology conditions play an important and even decisive role in the success or failure of the tunnel construction.
Should not only be detailed geological survey and exploration in exploration stage, as accurately as possible to grasp the tunnel project within the scope of the rock properties, the strength of rock mass, complete degree, ground stress field, the stable ability, the condition of groundwater state, the harmful gas and geothermal data, and according to these raw materials, preliminary selected appropriate construction methods, determine the corresponding construction measures and form a complete set of construction machinery.
Moreover, due to the complexity of geological conditions and the limitations of exploration methods, it is still inevitable that unexpected conditions occur during construction.
Therefore, in the construction of the long tunnel, it is necessary to take some technical measures such as test guide pit (such as qinghan tunnel in Japan), horizontal advance drilling, acoustic detection and lead guide pit, so as to further investigate the geological conditions in front of the excavation and timely grasp the changes.
In order to modify the construction method and technical measures as soon as possible.
The highway tunnel is a building with a flat shape. Under normal circumstances, there are only two working faces, namely, the inlet and the outlet, compared with the bridge and line engineering.
The construction speed of the tunnel is slow and the construction period is long.
Therefore, it is necessary to excavate additional auxiliary works such as vertical shaft, inclined shaft and horizontal hole to increase working face and speed up tunnel construction.
In addition, the tunnel section is small, the worksite is long and narrow, some construction procedures can only work in sequence, and some procedures can be along with the tunnel longitudinal development, parallel operation.
Therefore, the construction requirements to strengthen management, reasonable organization, avoid mutual interference.
The equipment inside the hole and the pipeline layout should be carefully considered and properly arranged.
Tunnel construction machinery shall be compact and durable.
The underground construction environment is poor, and may even worsen it during the construction, such as the harmful gas generated by blasting.
Effective measures must be taken to improve, such as artificial ventilation, lighting, dustproof, muffling sound, sound insulation, drainage, so that the construction site in accordance with health conditions, and have enough illumination, in order to ensure the health of construction personnel, improve labor productivity.
Most highway tunnels pass through mountains, so construction sites are generally located in remote mountains and narrow valleys, often far away from existing traffic lines, inconvenient transportation, and difficult supply. These are also one of the issues that should be considered when planning tunnel projects.
Highway tunnel is buried in the ground, once built, it is difficult to change, so in addition to careful planning and design in advance, the construction should be done without any future problems.
Of course, the tunnel project also has many advantages. For example, the construction can not be affected by the change of day and night, the change of seasons, the change of climate and other natural conditions.

(One station foundation drilling .)
Types of Pile Foundation
Pile foundation can be divided into two types: end bearing pile and friction pile.
The former refers to the pile through the soft soil and reach the rock or hard soil;
The latter refers to the pile hanging in the soil and bearing the weight by using the friction between the pile and the soil.
The Characteristics of Pile Foundation
Pile foundation construction workload is large, generally a project to the construction of dozens to hundreds of piles, and often need to be completed in a short time, pile into more procedures, need to cooperate with more work.
Most of the construction sites are very limited, or even very small, while the site has more equipment and facilities, more materials and frequent movement of pore-forming and perfusion equipment.
When drilling holes with washing fluid, the site is not easy to dry and level, and the amount of slag discharge is large.
Because of the great fluidity of pile foundation construction, temporary erected lines are mostly used in the site, and municipal power supply is introduced as power and lighting.
The outdoor operation of pile foundation construction is greatly affected by natural conditions, and the construction conditions are different from one project to another.
