摘要
南黄海海相中—古生界具有厚度大、埋藏深、构造复杂、岩性纵向非均质性强、浅部强反射界面能量屏蔽、碳酸盐岩层内部能量弱等特点。青岛海洋地质研究所联合中石化海洋石油工程有限公司、上海物探分公司(原第一海洋地质调查大队),通过持续的科技攻关,逐渐形成了适用于研究区内地震地质条件的"高富强"(高覆盖次数、富低频、强震源)地震勘查技术,获得了较高品质的海相中—古生界反射资料。2015年在崂山隆起上落实了多个大型中—古生界圈闭构造,为区内油气调查与勘探的突破提供了技术支撑。
The Mesozoic and Paleozoic marine strata in the South Yellow Sea Basin are characterized by huge thickness,large buried depth,complex structure,vertically heterogeneity of lithology,shallow high-reflection shield,and weak internal reflection of carbonate rocks.Qingdao Institute of Marine Geology,joined hands with Sinopec Offshore Oil Engineering Corporation,through continuous efforts,has developed a ＂HRS＂assemblage（High coverage,Rich low-frequency and Strong seismic source）of seismic exploration technology,in accordance with the seismic and geological conditions of the South Yellow Sea Basin.With the technology,the authors have acquired high quality reflection data of Meso-Paleozoic marine strata and defined several large Meso-Paleozoic structural traps at the Laoshan Uplift in 2015,which provides the technical support for the breakthrough of oil and gas exploration in the South Yellow Sea Basin in the near future.
