THE KEY SEISMIC TECHNOLOGY AND RESULTS: BASED ON THE PRACTICE OF REGIONAL MARINE GEOLOGICAL SURVEY IN SOUTH YELLOW SEA
-
摘要: 以南黄海区域地质构造特征调查为目标,开展采集、处理技术方法攻关和海上试验等工作,形成了大容量多层震源、长缆深沉放多道地震采集技术和基于长排列、低信噪比的资料成像处理技术,提高了地震资料的成像品质,获得了深部地层的有效反射;得出了前新生代残留盆地分布面积大,中、古生代海相沉积地层发育,千里岩隆起区是扬子块体与华北块体碰触接触带等新认识,对南黄海区域地质与油气资源前景研究意义重大。Abstract: To meet the needs of the regional marine geological survey in the Southern Yellow Sea,methodological research and testing have been carried out for seismic data acquisition, processing and other technology. Upon the basis, we found a series of the seismic data acquisition technology which are effective, such as the large-scale multi-level airgun array, the long cable in deep water and the seismic imaging processing technique based on the long spread and low S/N ratio data. With the efforts,the quality of seismic data imaging is improved and the effective reflection of deep buried formation obtained. The newly gained knowhow is of great significance to the study of regional geology and oil and gas exploration in the South Yellow Sea. We found from the new data that the pre-Cenozoic residual basin is larger than previously thought,the Mesozoic-Paleozoic marine deposits are well developed in the region and the Qianliyan uplift is the contact between the Yangtze block and the North China block.
