Performance requirements of through-cable drill pipe measured while drilling
The central cable drill pipe is the component with the most complex force and the worst working condition in the process of directional drilling. During the drilling process, the central cable drill pipe shall not only bear the pushing and pulling force exerted by the drilling rig and the counter torque of the screw drilling tool, but also serve as a medium channel to transport mud or other pressure medium to the bottom of the hole. At the same time, during the construction of near-horizontal long drilling and ultra-long drilling, drilling into the lower inclined hole or branch hole will produce additional bending stress, which can easily cause fatigue damage of the drill pipe. The central cable drill pipe is also the signal transmission device between the hole bottom inclinometer unit and the orifice inclinometer, which shall ensure real-time, safe and reduced signal transmission between the hole bottom inclinometer unit and the orifice inclinometer.

Four Technical Characteristics of Cable Drill Pipe
The 1. drill pipe body adopts G105 and S135 oil pipe conforming to API standard for production. Through overall heat treatment, the overall mechanical property can be improved and the service life can be prolonged. In order to reduce the connection point of drill pipe and meet the use requirements of narrow space in underground coal mine, the length of drill pipe shall not exceed 3m. And the use of a larger inner diameter of the rod can increase the overall inner diameter of the drill pipe, reduce the loss of liquid kinetic energy in the transmission process, and can reduce the overall quality of the drill pipe. 2. thread structure The force of the thread structure is relatively complex, and fatigue failure or fatigue fracture is prone to occur under the action of various loads such as tension, compression, torsion, and bending. previously made

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.
