Grasping the real-time and accurate downhole information is an important step for realizing optimized drilling, which is also the direction of many drilling companies. Because there are many types of signals with different amplitudes and frequencies that change all the time, in the meantime the signals are generated from sources far away from the ground as well as high temperature and high pressure appear in these positions, leading big challenges in measuring these signals. Measuring approach based on mud pressure pulse is one of the most popular methods used today. For this approach, sensors are placed downhole to monitor the information and the information is sent to the mud channel in the form of pressure pulse, then the sensors and systems on surface are used to treat these mud pulses. In this paper, the mechanism of the measuring the downhole information via mud pressure pulses is presented, including the emission of the downhole signals, the attenuation of the mud pressure in the mud channel, and the handling of the signals on surface. Based on the existing technology, some optimization measures are developed in the point structure of the mud channel, emission of the downhole signals, and disposing of the surface signals. In addition, the detailed operation procedures are also presented.
