Abstract
Aiming at the problem of limited communication distance when the current wireline measurement system is applied in directional drilling to realize the advanced detection and control of mine disaster factors, a mine mud pulse measurement-while-drilling (MWD) system has been developed. However, there is no means to verify and detect the communication distance of this new system in production, acceptance and testing. Based on the communication principle of mud pulse MWD system, this paper establishes a communication data model, analyzes the factors affecting the communication distance of this system, and finally, through building a test platform, tests the communication effect of the mine mud pulse MWD system by simulating the communication distance of 3000 meters. The results show that the pulse MWD system can achieve communication while drilling of 3000 meters or longer.
