Traditionally,the geophone point combination is commonly used in the towing type sub-bottom seismic profile acquisition system.If the water depth is sufficient,the impact of the group internal distance is ignorable in the traditional towing type acquisition system.However,it is easy to cause wave distortion and loss of high frequency information when the sea water is shallow.Therefore,we take the advantage of the multi-channel seismic recording to make some improvement on the towedstreamer sub-bottom profile acquisition system.The new system is using a way of towing construction,multiple seismic traces and non-combination of geophone to collect data.The data from every geophone point will be acquired.In the meantime,the new acquisition system can simultaneously monitor the original single shot record,and stack channel before and after the time difference correction.
