This paper has analyzed the difficulties in the exploration of the transitional zone in Kendong area, such as the unfavorable exciting and receiving conditions of the seismic wave and the development of the disturbing wave. The seismic wave excitation and receiving as well as measures for improving the detector are discussed, the improvement of the detector and the couple effect of the surface is studied, the parameters of air gun source and dynamite source are optimized, the detector fixation method is improved, and the real time fixed location monitoring of the detector is carried out. With the adoption of the above measures, the signal-to-noise ratio of the seismic data was raised, and the seismic data acquisition task was successfully completed.
