Abstract：In recent years, variable-depth streamer acquisition is a kind of seismic exploration technique. The mainly propose of this acquisition is to suppress ghost and obtain high quality broadband seismic data. The commonly used variable-depth streamers are linear streamer and curved streamer, which could obtain more high frequency and low frequency information. By comparing the different parameters of seismic data and de-ghosting data, we found that curved variable-depth streamer data in wave-field analyze showed better characteristics, and have a higher signal-to-noise ratio. That is to say, the observation system of curved variable-depth streamer is superior to the linear variable-depth streamer. According to the result, it is recommended that curved variable-depth streamer is a better choice in the seismic exploration.
