What are the points to be aware of when buying pdc drill bits

 PDC drill bits have high drilling efficiency and low loss, the following are the places to pay attention to PDC drill bits:

1. Match the specification of the drill bit with the formation

Bit diameter: It should be matched with the drilling diameter, too big or too small will affect the drilling efficiency and bit life.
Number and shape of cutter flanks: Choose the appropriate number and shape of cutter flanks according to the hardness and lithology of the formation. For hard strata, it is better to choose the drill bit with more cutter wings and sharp shape; for soft strata, it is better to choose the drill bit with fewer cutter wings and rounded shape.
Thickness of diamond layer: The thickness of the diamond layer directly affects the wear resistance of the drill bit, the higher the hardness of the formation, the thicker the diamond layer should be.

2. Drill Bit Quality

Brand and Manufacturer: Choose a drill bit made by a famous brand or a manufacturer with a good reputation, the quality is more guaranteed.
Material: The material quality of the PDC drill bit directly affects its performance. High-quality diamond and matrix materials should be selected.
Manufacturing process: Precise manufacturing process can ensure the dimensional accuracy and surface finish of the drill bit, and improve the service life of the drill bit.
Appearance inspection: The appearance of the drill bit should be carefully inspected for cracks, defects, etc. before purchase.

3. Drilling parameters

Drilling pressure and rotation speed: Different formations have different requirements for drilling pressure and rotation speed, so you should choose the appropriate parameters according to the formation conditions and bit specifications.
Pump pressure and displacement: too much or too little pump pressure and displacement will affect the life of the drill bit and drilling efficiency.

4. After-sales service

Technical support: When purchasing drill bits, you should choose the manufacturer that provides good technical support so that you can get timely solutions when you encounter problems during use.
After-sales service system: A perfect after-sales service system can ensure the normal use of the drill.

5. Price

Cost-effective: Price is not the only criterion for choosing drills, you should consider the quality, performance and price of the drills, and choose the products with high cost-effectiveness.
Don't be greedy for cheap: too low a price may mean that the quality of the drill is not satisfactory, and problems may occur during use.

6. Other considerations

Drilling fluid: Choosing the right drilling fluid can effectively protect the drill bit and improve drilling efficiency.
Drilling tool combination: A reasonable combination of drilling tools will also affect the performance of the drill bit.

Regular inspection and maintenance: Regularly check the wear of the drill bits and replace the worn bits in time.

Summarize

Purchasing PDC drill bits is a systematic project that requires comprehensive consideration of many factors. Only by choosing a drill bit that is suitable for the formation conditions and of reliable quality and using it reasonably can the drilling operation be ensured to go on smoothly. If you don't know how to choose the right PDC drill bit, click the link below to contact our professional team directly.

What are the differences bewteen core drilling bits and pdc drilling bits

  Although both core drills and PDC drills are tools used for drilling and sampling, there are significant differences between them in terms of material, structure, and scope of application. Core Drill Definition: A core drill is a broad concept that refers to all drills used for coring operations. It can be a variety of types such as tungsten carbide bits, PDC bits, diamond bits and so on. Function: Mainly used to remove a cylindrical section of core sample from different types of materials for subsequent analysis and research. Material: Various materials, including carbide, diamond, PDC, etc. Different materials are selected according to the hardness and toughness of the drilling material. Structure: Relatively simple structure, mainly consists of drill body, inner cylinder and outer cylinder. Application:  Wide range of applications, including geological exploration, engineering survey, mineral exploration, etc. PDC Drill Bit Definition: PDC drill bit is a special coring dr...

What is the diffirence between slurry pump and mud pump?

Many people confuse the concepts of   slurry pump s and   Mud Pump s, but in terms of practical applications or the characteristics of the conveying medium, there are indeed countless similarities between the two pump. Concept analysis of slurry pump and mud pump: The slurry pump is mainly suitable for industries such as mining, power plants, dredging, metallurgy, chemical engineering, building materials, and petroleum. Mud pump is also a popular concept of a broad pump, and different regions, habits, and ultimately involve different pump types. Mud pumps are used in the field of oil drilling. In fact, some non clean water pumps and mud pumps such as sewage pumps and slurry pumps are also commonly referred to. The similarities between slurry pump and mud pump: 1. In terms of working principle, it belongs to a centrifugal pump. Conceptually, it refers to a mechanical device that converts electrical energy into the kinetic and potential energy of the medium by increasing the ene...
