    摘要
  • 随着南黄海地震技术攻关的不断深入以及油气调查与勘探的持续开展,海相中—古生界的地震反射成像质量得到了显著的提高,但海相下古生界的地震资料仍存在信噪比较低、反射能量较弱、波组连续性较差等问题。通过分析区内地层结构、构造复杂性、强反射界面对能量的屏蔽作用、多次波发育情况、碳酸盐岩地层内部物性差异等地震地质条件,提出了进一步改善海相下古生界反射品质的地震调查技术攻关方向:研发富低频强能量震源系统;针对不同构造单元的信号接收系统,获取富低频震源—电缆沉放深度组合参数;研发针对性的地震资料攻关处理技术以及开展新采集技术在本区的应用试验。
    In the past years, with the rapid progress of seismic technique and continuous oil-gas exploration in the South Yellow Sea Basin, the quality of seismic reflection data for the marine Meso-Paleozoic has been much improved, except for the marine Lower Paleozoic, which remains under low signal-noise ratio, weak reflection energy and poor impedance continuity. In this paper, after analysis of stratigrafic framework, structural complexity, energy shield effect of strong reflection interface, multiple reflection and internal physical property of carbonate rock, we make a detailed summarization of the seismic geological conditions of the South Yellow Sea Basin. Upon the basis, some suggestions on seismic investigation technique are given to enhance the seismic quality of marine Lower Paleozoic, that includes research and development of the multi-channel seismic source system with strong energy and low frequency;develop the multi-channel seismic receiver system aiming at different tectonic units;acquirement of depth parameters about the source-receiver system; development of targeted seismic processing technology and application of new acquisition technique in the area.
