| 英文摘要 | The northern South China Sea is a rifted continental margin. It has experienced complicated geological evolution and has been proved to have the prospect of oil and natural gas. In this paper, the velocity structures of strata in the northern South China Sea are obtained and analyzed by the velocity structure calculation of far offset refractive wave method using the long cable multi-channel seismic data collected in a northern region of South China Sea and in addition, the conception of non first-arrival refractive wave is proposed. In this method, refractive horizons are recognized; travel times of the same horizon in different common offset sections and different horizons in the same common offset section are collected. The velocity structure of the same horizon is calculated by the difference of travel-time in different common offset sections. The application of this method in a northern region of South China Sea reveals the whole velocity structure and the velocity change prosperities of the Cenozoic strata of different ages. The application provides a fresh sight using far offset refractive velocity structure to study the Cenozoic geological evolution of South China Sea. The results show that far offset refractive wave method supplies more geological information compared with the conventional first-arrival refractive wave method; the preliminary application provides a new insight for the research of far offset refractive wave method. |
