Compared with a vertical well, the underground drill string state in the special process wells is more complex, the underground parameters needing to be obtained are more numerous, and the requirements on the transmission rate and the transmission data volume of underground information transmission are higher. The sound wave transmission technology in the current underground information wireless transmission technology shows better development momentum due to the advantages of high transmission efficiency, low cost, wide application range and the like, and if the method can be widely applied to the field of drilling engineering, the method can certainly and greatly promote the realization steps of real-time monitoring and intelligent control of the underground process. However, the problem of noise generated by rock breaking of a drill bit, circulation of drilling fluid, operation of a drilling machine and the like in the drilling process can not be well solved all the time, and finally the implementation of the underground information acoustic transmission technology is influenced. Among many noises, the power drill operates by starting the pump, so that the noise generated by the collision and friction between the drill bit and the well wall or borehole becomes the most main interference factor of the underground information transmission acoustic carrier due to the characteristics of large intensity and wide frequency band. If the power drilling tool stops working in the inclination measuring process and starts working in the drilling process, the drilling noise of the power drilling tool can be effectively eliminated. Therefore, the research and development of a power drilling tool working state control tool for controlling the working state of the underground power drilling tool according to the drilling state has great significance for inhibiting and avoiding noise in the directional well logging process, and has an important effect on the realization of an underground information acoustic transmission technology.
