1. The importance of diamond drill bits for rock

In the process of geological drilling and engineering exploration, diamond drill bits are widely used drilling accessories. How to improve the service life of drill bits is a problem that diamond drill bit manufacturers have been considering. The method of prolonging its service life should be considered from the three aspects of the raw material, manufacturing process and operation technology of the diamond drill.

Ⅱ. How to improve the service life of diamond drill bits for rock?

1. Raw materials

Diamond drill bit manufacturers and sales purposes are closely related. If it is a technology-based enterprise pursuing quality, they will strictly control the procurement of production materials. Only high-quality raw materials can ensure that the quality of the drill bit stands out among many brands. This is also the fundamental way to improve the service life of diamond drill bits.

2. Production process

Electroplated diamond china tungsten carbide drill bits have been developed for many years, and their production process has undergone many major changes. The production processes of different manufacturers are very different. Due to their respective operations, there is currently no complete system of diamond drill production processes that have been made public. To be sure, the production process is a direct factor in determining the quality of diamond drill bits.

3. Operation technology

If the choice of drill bit is the primary reason for its service life, then the actual operation is the secondary reason. No matter how good a diamond bit is, if there is no proper operation method, not only the ideal footage efficiency cannot be achieved, but it will also affect the wear of the bit. For example, in normal drilling, if the cleaning fluid cannot circulate normally, then the bottom of the generated high-temperature and high-speed rotation of the drill bit cannot be taken out, which can easily lead to drill bit burning accidents, not to mention the service life problem.

What are the two basic kinds of roller cone bits?

Common Tooth Shape of Roller Cone Bits

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.

Classification of Drill Bits

There are many manufacturers of tooth bits, and these china diamond 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;

8 – Insert teeth, extremely hard, highly abrasive formations.

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:

1. The double action of impact and shearing breaks the rock, both the impact of the teeth and the shear caused by sliding, the rock breaking efficiency is high.

2. It is suitable for a wide range of formations and is suitable for drilling in all formations.

3. The self-washing effect of the drill bit is good, and it is not easy to mud pack.

4. Lower cost of drill bit.

Bit Selection in Oil Drilling Bits

In the process of drilling, drill bit 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 drill bit selection 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 oil drilling bits 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.

Now the oil drill bit cost is reasonable, if you have needs, please contact us.

As a rock drill bit supplier, we can offer sorts of related products for sale, if you have needs, please contact us.
