摘　　要：对山东省海阳市冷家庄东南近岸海域浅、中深层地层声学探测剖面进行了分析对比，对研究区内的地震地层层序和基岩构造特征进行了判识，探明研究区存在着3个地震反射波层组，分别代表了3套不同形成时代、不同沉积结构的地层，综合海底浅层柱状取样结果及陆上地层露头情况，推测这3个地震反射波层组分别与第四纪浅海相泥砂质沉积、白星纪莱阳群中上部的中、薄层粉砂岩和莱阳群的厚层石英砂岩相对应。并且，发育于基岩内的断层构造在第二、三反射波层组内具有明显显示，但均未延伸至第一反射波层组。On the basis of analysis of shallow and mid-deep acoustic surveying profiles in offshore area southeast of Lengjiazhuang, Haiyang, Shandong Province, the paper discusses seismo-stratigraphic sequence and structure characteristics. Three seismo-stratigraphic sequences are given according to different ages and sedimentary formations. Together with off shore sub-bottom samples and inshore crop,we supposed that three seismo-stratigraphic sequences correspond respectlvely to Quaternary mudwsand sediment,Cretaceous thin siltstone of Lalyang Group and thick quartz sandstone of Laiyang Group. In addition,fracture existing in the second and third seismo-stratigraphic sequences haven' t extended to the first seismo-stratigraphic horizon.
