摘要: 为了研究渤海—山东半岛—南黄海一线的深部构造特征, 利用海区气枪震源和陆区爆破震源探测, 于2013年在胶东、渤海和南黄海布设了一条海陆联合深部地震探测剖面。海陆联测剖面包括渤海和南黄海两条海底地震仪(Ocean Bottom Seismometer, OBS)测线和一条陆上地震测线, 是首次在南黄海地区布设的OBS深地震测线。文章对南黄海段测线上的海底地震仪数据进行了数据预处理, 其中包括地震数据解编处理、截裁处理等, 结果表明, 此次实验海底地震仪记录质量良好, 可以清晰地识别出Ps、Pg、PmP等多组震相, 还首次观察到了来自千里岩隆起带上的P波震相, 说明数据处理流程是可行的; 再结合地质地球物理资料, 初步分析了南黄海不同构造单元的震相特征, 为下一步地壳速度结构的模拟及解释工作奠定了良好的基础。

Abstract: In order to study the deep tectonic characteristics along the line of Bohai Sea-Shandong Peninsula-South Yellow Sea, using marine air gun source and land explosive source detection, the Bohai Sea-Shandong Peninsula-South Yellow Sea onshore-offshore joint deep seismic survey profile was carried out in 2013. The onshore-offshore deep seismic profile comprises two ocean bottom seismometer (OBS) seismic lines in the Bohai Sea and the South Yellow Sea and one onshore seismic line. This is the first OBS seismic line in the South Yellow Sea. After data preprocessing of South Yellow Sea OBS, including data decoding and data cutting, etc., the results show that the OBS recording quality is good. We can not only identify the seismic phases such as Ps, Pg and PmP but also observe the P-wave seismic phases from the Qianliyan uplift zone for the first time, which means the data processing is feasible. Combined with geological and geophysical data, a preliminary analysis of the phase character in different structural units of the South Yellow Sea was carried out, laying a good foundation for future simulation and interpretation of crust velocity structure.
