Electromagnetic measurement while drilling (EM-MWD) as a new technology in the ifeld of petroleum exploration and development, with the signal transmission high rate, it is not affected by the drilling lfuid medium, low cost. Briefly introduces the characteristics of electromagnetic wave transmission technology, describes the working principle and system composition of wireless electromagnetic measurement while drilling tools, and puts forward a electromagnetic wave with key module drill measurement system. At the same time as the test system performance, analysis of the factors inlfuencing the signal transmission: formation resistivity, carrier frequency, the resistance per unit length of drill string. The results show that, the electromagnetic wave MWD system has wide application prospects in the mine detection.
