Pearldrill Drilling Rig And Drill bits

With the continuous development of science and technology, every company will choose products with good wear resistance, for example, the drill bit for cutting edge is called PDC core bit. The drill bit is an integrated drill bit, the whole drill bit has no moving parts, the structure is relatively simple, and it has high strength, high wear resistance and impact resistance. It is one of the three new drilling technologies in the world in the 1980s. Field use proves that when drilling in soft-medium-hard formations, the diamond bit has the advantages of high speed, large footage, long life, stable work, fewer downhole accidents, and good well quality. Diamond drill bits are not only used for a long time, but can also be reused. The use effect of the returned diamond drill bit is similar to the factory diamond bit, which can save a lot of drilling costs. The rock breaking effect of PDC core bit is completed by diamond particles. To know the rock breaking effect of the drill bit, it is n...

  The degree of wear on  drill bits  can be determined through the following methods: Observe the appearance of the drill bit: Observe whether there are obvious wear marks on the appearance of the drill bit, such as blunt edges or surface wear marks. Measure the diameter of the drill bit: Use a caliper or other measuring tool to measure the diameter of the drill bit and compare it with the diameter of the new drill bit. If the diameter decreases, it indicates that the drill bit has been worn. Observation of drilling effect: Observe whether there are any abnormal situations during the drilling process, such as slower drilling speed, increased drilling resistance, and decreased quality of drilled rock cores. If these situations occur, it indicates that the drill bit may have been worn. Listen to the drilling sound: During the drilling process, pay attention to the friction sound between the drill bit and the rock. If the sound becomes abnormal, it indicates that the drill b...

  PDC is a kind of bit which uses PDC as cutting edge. It is an integrated bit, which has the advantages of high wear resistance, high strength and impact resistance. The bit is one of the three new drilling technologies in the modern world because of its simple structure without movable parts on the body. A large number of applications have proven that diamond composite bit has the advantages of high speed, more footage, long service life, stable operation, less drilling accidents and good borehole quality when it is used in soft medium hard formation. PDC Drill Bit s Product Features: 1. Soft to medium-hard formation application Medium Parabolic crown profile and heavy cutter density provide high ROP in medium to hard formations with medium compressive strength and small abrasive layers. 2. Multi-function hydraulics The deep blade design can get high ROP in medium to hard formations and can effectively cool the bit in hard and abrasive formations 3. Longer Bit Life High inte...

  When we want to determine the required drill bit size, we can refer to these aspects to determine: 1. The diameter of the wellbore: Firstly, it is necessary to measure the wellbore diameter to determine the size of the drill bit that needs to be used. 2. Drilling depth: The drilling depth is also one of the important factors in determining the size of the drill bit. If the drilling depth is shallow, a smaller size drill bit can be used, while if the drilling depth is deep, a larger size drill bit needs to be used. 3. Drilling speed: Drilling speed is also one of the factors determining the size of the drill bit. If rapid drilling is required, a larger size drill bit is required, while if the drilling speed is slow, a smaller size drill bit can be used. 4. Type of drill bit: Different types of drill bits are suitable for different drilling conditions. For example, scraper drills are typically used for soft rocks, while diamond drills are suitable for hard rocks. Therefore, it is ...

Use and maintenance of drill bits: 1. Choose a suitable drill bit:  Before using a drill bit, it is necessary to select the appropriate type and specification of drill bit based on drilling conditions and needs. 2. Installing the drill bit:  When installing the drill bit, it is necessary to ensure that the connection between the drill bit and the drill pipe is firm, and to correctly install the cutting teeth of the drill bit. 3. Maintain appropriate drilling speed and pressure during the drilling process:  Excessive drilling speed and pressure can lead to premature wear and damage of the drill bit, while too small can affect drilling efficiency. 4. Regular inspection and maintenance:  Regularly check the wear of the drill bit and replace severely worn components in a timely manner. At the same time, it is necessary to regularly clean and lubricate the drill bit to extend its service life. 5. Storage and preservation:  When storing and preserving drill bits, it i...
