Main Functions of Cable Directional Drill Pipe
The cable directional drill pipe is an important part of directional drilling equipment. It is a component with complex force and harsh working conditions in the process of directional drilling. Its main functions include: 1) transmitting the axial pressure exerted by the drill bit during drilling to the drill bit, and bearing the reverse torque of the bottom hole motor; 2) transmitting the pushing and pulling force exerted by the drilling rig on the drilling tool during tripping; 3) As a medium channel, the flushing fluid is transported to the bottom of the well. In order to facilitate the handling of accidents in the hole. The cable drill pipe can be used for both directional drilling and regular rotary drilling. Therefore, the cable drill pipe should also meet the requirements of applying torque to the drill bit during regular rotary drilling.

The cable drill pipe is a special drill pipe for directional drilling construction in underground coal mine, and its excellent sealing performance and signal transmission performance ensure that the drilling parameters at the bottom of the hole can be transmitted to the orifice signal receiving device in real time and accurately. The drill pipe is made of high-strength alloy steel for oil drilling tools, which has excellent comprehensive mechanical properties. The inspection of the drill pipe is carried out in accordance with the acceptance standards of oil drilling tools, and the quality of the drill pipe is fundamentally guaranteed.

Cable water passage cable water injection water beneficial mine technology
The main function of the water injector is to inject pressure water into the drill through drilling to achieve the effects of slag discharge and cooling and dust reduction of drilling tools. The water injectors produced by our company are divided into low pressure type and high pressure type, the low pressure type can withstand 0.6-1.2mpa pressure, and the high pressure type can withstand pressure within 60mpa.

Directional Reaming Bit Directional Bit Beneficiation Technology
Directional drill bit (PDC) is a special superhard material synthesized by synthetic diamond and cemented carbide at one time under high temperature conditions. It not only has the advantages of high diamond hardness and wear resistance, but also has the characteristics of cemented carbide, such as strong impact resistance and large cutting edge.

Directional Bit Diamond Directional Bit Beneficiary Technology
Directional drilling is a drilling method that uses the natural bending law of the borehole or the use of artificial oblique tools to extend the directional borehole to the intended target according to the design requirements. It can also be explained by the technology and science of drilling to reach a predetermined subsurface target and deflect the borehole in a specific direction. That is, the drilling axis is purposefully changed from curved to straight or from straight to curved. At the same time, the hole bottom guide device monitors the drilling parameters in real time, and then determines the oblique direction of the hole bottom screw motor. The key part of the technology lies in the motor drive device in the hole and the matching measurement technology. First, the high-pressure water is delivered to the motor in the hole through the drill pipe, and the rotor inside the motor in the hole is washed by the high-pressure water.
