摘要
利用2007年基于冀东南堡海域所做的浅地层剖面资料,根据沉积物的岩性变化,沉积物密度、含水性、含气程度及沉积层构造、层面特征、沉积层延伸与错断及侵蚀构造等形成的反射波记录对第四纪沉积层进行解释。对浅部主要地层层序进行了划分,并分析了该区域主要灾害地质因素,如埋藏古河道、浅层气、断层等。并对浅地层剖面解释中遇到的问题(如二次波等)进行了探讨。
In this paper,upon the interpretation of shallow seismic profile data Brom Nanpu waters in Jidong acquired in 2007,the authors established the Quaternary stratigraphic seguence in accordance with the lithological changes,sediment density,water resistance,gas content,sediment structure,surface features,continuity and extension of sediments.Interpretation was also made for major geohagard feafures,such as buried river channels,shallow gas,active faults.The problems encountered in shallow seismic interpretation,such as the second wave and so on,are discussed.
