Study Of Multi-channel High-resolution Seisimic Data Processing In Offshore Of Yellow Sea

China is a maritime country, it has a broad shallow continental shelf area. Offshore is the earliest and most frequent area for marine development and utilization, and it has rich resources. With the rapid development of economy and society, the pressure of resources and environmen is more and more serious. The development and utilization of resources has become the focus of attention.Yellow Sea region are close to Liaodong Peninsula Economic zone and Shandong Peninsula Economic zone, which lies in an advantageous position. With the rapid development of China's economy and society, marine engineering has been constructed increasingly. Therefore, this region need to be surveyed. And high resolution seismic prospecting with small trace spacing, short arrange can complete geological tasks very well. It is also has great significance for understanding the condition of Submarine geomorphology, Quaternary geology, and shallow ground faults.Firstly, according to the requirements of the shallow geological survey, seismic exploration instrument and high resolution acquisition parameters are analyzed briefly and then high resolution seismic data processing methods is discussed. By processing the actual data, the author has found that multi-channel shallow seismic prospecting can remove the multiple waves and noise suppression better than the traditional seismic exploration method. Based on the processing methods such as prestack noise attenuation and predictive deconvolution seismic wavelet compression, the resolution is greatly improved and various noise components are removed targetedly. The signal is enhanced effectively through stacking a multi-channel seismic horizon and suppressing random noise and multiple wave components. And finally the stack modification promotes seismic profiles much better, which can also develop a shallow high-resolution marine seismic data processing method. The thesis develop a shallow high-resolution marine seismic data processing method by processing the Yellow Sea Seismic data. According to the analysis of real data, good first-hand material has got by using digital collection system which was reseached by laboratory independently. Then through the high resolution seismic processing method, multiples and the other major noises are suppressed in some degree , the high-SNR high-resolution sections are ultimately achieved through high-resolution data processing method, it is useful for the subsequent data interpretation.
