A PRELIMINARY ANALYSIS OF SEAWATER SEISMIC IMAGING METHOD AND ITS APPLICATION IN MARINE GEOLOGICAL SURVEY

With the rapid development of geological survey in marine areas,it is highly demanded that the seismic imaging method which has played an important role in geological survey on land be extended to the offshore waters.However,owing to the difference between the land and sea,the seismic imaging method used in the sea is different with that used on land.The seismic image in water is in fact a kind of shallow profiler receiving reflected waves.It is so called single channel seismic or multiple channels seismic while reflected waves are received by a single channel or multiple channels.Viewing the advantages of the method in wave transmitting and receiving,the seawater seismic wave imaging method can be applied as a supplement to shallow profiling and other marine seismic surveys.
