The formation principle and influence of directional drill pipe near horizontal directional drilling technology is an advanced technology in the field of drilling engineering. It is applied to coal mines and started in the western developed countries such as the United States, Germany and Britain in the 1960 s and 1970 s. Many coal mines in my country, such as Songzao, Tiefa, Huainan, Shanxi Yamai Daning, etc., also introduced this technology in the mid-1990s. At present, China's coal mines are widely used in directional drilling technology for the screw motor oblique supporting wired drilling measurement system. This technology is mainly used in underground rock formations and more stable coal seams because of its high precision, long distance and construction flexibility.
Formation principle and influence of directional drill pipe
Near horizontal directional drilling technology is an advanced technology in the field of drilling engineering. It is applied in coal mines and started in the United States, Germany, Britain and other western developed countries in the 1960 s and 1970 s. Many coal mines in my country, such as Songzao, Tiefa, Huainan, Shanxi Yamai Daning, etc., also introduced this technology in the mid-1990s.
At present, China's coal mines are widely used in directional drilling technology for the screw motor oblique supporting wired drilling measurement system. Because of its high precision, long distance and construction flexibility, this technology is mainly used in underground rock and stable coal seam gas drainage long directional drilling and geological exploration directional hole construction.
The important feature of the wired measurement while drilling system is the signal transmission between the probe and the receiving end by the directional drill pipe. Therefore, the performance stability of directional drill pipe will have an impact on directional drilling construction.
Kilometer directional drilling rig in coal mine gas control, can achieve long drilling directional drilling and control of the drilling trajectory, to ensure that the drilling trajectory in the target layer effectively extended, and can carry out multi-branch hole construction, with high drilling efficiency, one hole multi-purpose,The advantages of centralized extraction are increasingly reflected, and the real-time control of the azimuth angle, inclination and elbow direction of the directional drill pipe needs to measure the angle.
