1. product introduction The central cable drill pipe is also called the drill pipe measured while drilling. It is mainly used in the deep hole directional drilling of the kilometer directional drilling rig. Directional drilling technology is one of the most advanced drilling methods in the world. It is a drilling method that uses the natural bending law of the borehole or the use of artificial skew tools to extend the borehole to the predetermined target according to the design requirements, and can drill to the designated position according to the pre-designed drilling trajectory. The central cable drill pipe is the signal transmission device used in directional drilling, and it is also an important part to ensure the smooth implementation of directional drilling. Due to the harsh environment in which the drill pipe is used, the quality of signal transmission and the stability of the rod body have
1. Product Introduction
Center cable drill pipeAlso known as measurement while drilling drill pipe, mainly used in km directional drilling rig for deep hole directional drilling.
Directional drilling technology is one of the most advanced drilling methods in the world. It is a drilling method that uses the natural bending law of the borehole or the use of artificial skew tools to extend the borehole to the predetermined target according to the design requirements, and can drill to the designated position according to the pre-designed drilling trajectory.
The central cable drill pipe is the signal transmission device used in directional drilling, and it is also an important part to ensure the smooth implementation of directional drilling. Due to the harsh environment of the drill pipe, there are higher requirements for the quality of signal transmission and the stability of the rod body.
2. product advantage
The drill pipe is produced with G105 oil pipe conforming to API standard. The manufacturing process is divided into joint thickening integrated type and friction welding type. The rod body can improve the overall mechanics and prolong the service life through overall tempering treatment. The cable joint is customized with imported PPR(100) brand-new raw materials, with high mold precision and higher sealing effect than similar products. The communication cable is imported special conductor copper alloy cable, which can cope with various extreme use environments.
3. scope of application
Center cable drill pipeIt is generally required to construct in a complete coal seam (f≥ 1) or a stable rock layer (f≤ 6); it is mainly used for the construction of near-horizontal long-distance gas drainage drilling and water exploration drilling in coal mines, and can also be used for directional drilling construction such as ground and tunnel near-horizontal engineering drilling. Mainly used in coal mine underground directional drilling, coal mine underground rotary drilling and other geological controlled directional drilling conditions, as well as gas drainage, gas layer development, emergency rescue, detection and discharge of goaf water and geological structure.
Key words:
Technology, drilling, directional, drilling, drill pipe, coal mine, underground, use, use, main.
