Description
Technical Field

Background
At present, in an oil field drilling project, an underground information transmission technology which uses sound waves as carrier waves and a drill string as an information transmission channel can improve the transmission efficiency of underground data, reduce the dependence of data transmission on the environment in a well and reduce the cost of data transmission equipment, so that the underground information transmission technology becomes a hotspot of research in the field of underground information wireless transmission. 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. In the drilling and inclination measuring process, a drilling tool needs to be lifted up, the rotary table or the top drive is stopped from rotating, and the pump is kept on for circulation. The drilling tool stops rotating, friction noise between the drilling string and the well wall can be eliminated, and the drilling fluid circulation noise is low in intensity and can be ignored approximately. 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 the downhole noise controller for controlling the working state of the downhole power drilling tool according to the drilling state has great significance for inhibiting and avoiding the noise in the directional well logging process, and has an important effect on the realization of the downhole information acoustic transmission technology.
