Marine wave correction research on single channel seismic data and a subbottom profile

Owing to sea big wind wave and swell and so on, marine single channel seismic and subbottom profile data reflecting events often undulated, causing profile reflection horizons wrongs and confusions, and resolution and signal to noise ratio reduction. Therefore, according to the noise and the seabed reflection formation in the horizontal correlation with the change of frequency characteristics, as well as the comprehensive results of the previous studies, the land seismic data’s residual static correction processing in the statistical model trace’s cross-correlation method is used to reduce the influence of ocean wave on the reflecting events. in addition, in order to reduce of the effect of the high energy noise on correlation operation, uses the median filtering and smoothing filtering technology on the reflection events curve filtering are used to further reduce residual waves effects and related operational correction error. These methods will be integrated in the actual survey data processing of sea, large wind wave and swell under the influence of the wavy reflecting events become continuous and smooth, and under the sea clutter reflective layer it becomes clear and continuous, section signal-to-noise ratio and resolution are greatly improved.
