Abstract

In a sea area of China, the “single source-single streamer quasi-three dimensional seismic survey” method was ap-plied in the gas-hydrate investigation, and a satisfying three-dimensional (3D) image was obtained. The bin parameter is one of the important parameters that can influence the 3D imaging. According to the result of data, if a streamer length of 2400m (192 channels) is fixed, the best optimization bin size (transverse) should be 50m and processing bin should be half of the origi-nal acquisition size, i.e., 12.5m?25m, which can take into account of the authenticity and continuity of strata. A good quality of the quasi-3D seismic image can then be obtained.
