3.Product advantages
The diamond composite drill bit is made of high-quality steel, and is processed by vacuum automatic heat treatment equipment to increase mechanical properties. The ordinary type adopts domestic high-quality composite sheet to do knife wings, and the super-strong type adopts the United States.The blades produced by GE company, according to the different geological conditions, choose the corresponding quality grade, can achieve higher product cost performance, to achieve energy-saving and efficient economic indicators.
High-strength diamond bit blade wing adopts the newly developed ball diamond blade, which is characterized by fast drilling speed and strong impact resistance. When the drill bit is drilling, the lip is used for scraping the normal uniform formation rock, and the protruding part can inhibit the instantaneous large-scale footage when the drill bit encounters a gap during the drilling process, greatly reducing the accidental damage of the drill bit and improving the drilling level to deal with complex rock formations. Diamond composite drill bit adapts to the best rock formation parameters: The diamond composite drill bit produced by our company, according to the strength of the composite, is mainly suitable for drillingBetween 10 ≤F≤ 18, F represents the rock hardness coefficient, and the best suitable rock is as follows:
|
Line Number |
Type |
adapted rock formation |
|
1 |
Ordinary PDC bit |
Soft-medium hard rock with F<10 |
|
2 |
Reinforcing the PDC bit |
Medium hard rock with F = 10-12 |
|
3 |
High strength PDC bit |
Hard rock with F<18 |
4. Precautions
1. During normal operation, it is strictly forbidden to change the running direction suddenly to prevent the composite drill bit from falling off;
2. During normal operation, the main air path of the air compressor should not have air leakage, and sufficient air volume and air pressure should be ensured to extend the use time of the diamond composite drill bit;
3. When the new composite piece drill is used for the first time, it should be run in at low speed for half an hour, and then gradually used normally;
4, in the harsh geological environment, to reduce the shaft pressure and speed, to prevent the drill bit fracture;
5, in the normal drilling operation, if the midway to replace the drill bit, to strictly check whether there is debris in the hole, must ensure that the hole is clean before the use of new composite drill bit;
6. When using the new composite piece drill for the first time, pay attention to the cleaning of the drilling part to prevent sundries from affecting normal use;
7. During normal drilling operations, if the drill bit must be replaced midway, strictly check whether there are sundries in the hole, and ensure that the hole is clean before using a new composite drill bit;
8. It is strictly forbidden to use curved drill pipes to avoid the damage of the drill bit due to uneven force and accelerate the damage of the drill bit and affect the normal use time.
