摘要
Western South China Sea is the main exploration and development field for CNOOC with great exploration potential. In recent years, with the increasing of exploration intensity in deep formation, the authors made great breakthrough in geophysical exploration, seismic data acquisition and processing technology. According to geological features and the characteristic of the geophysical information in different basins of South China Sea, the paper proposes to make good use of traditional seismic data processing techniques and methodologies. At the same time, for the new problem in new field of complex geological conditions, the authors created new seismic data processing techniques and methods constantly, form a series of ripe seismic data processing technology gradually, and provide technical support for oil and gas exploration in northern South China Sea setting up "Daqing Oilfield at the Sea".
