渤海湾盆地辽东湾地区古近系地震相研究
|
摘要
对辽东湾地区古近系地层进行了研究,选择了可信度较高的地震反射内部结构和外部形态,辅助地震反射振幅、连续性等参数,对地震相进行了划分命名。在研究区6个地震层序中共识别出平行—亚平行席状地震相、前积地震相、楔状地震相、充填状地震相、透镜状地震相、丘状地震相及乱岗状地震相等多种类型。这些地震相在平面分布上具有差异性,在垂向演化上具有继承性。将地震相转变为沉积相,划分出了湖泊沉积环境的深湖—半深湖、滨浅湖、扇三角洲、近岸水下扇、三角洲、浊积扇等沉积相,预测出了有利沉积相带。
Seismic facies of Paleogene in LiaoDong Bay are divided and named mainly based on the reliable internal reflection texture and external shape of the seismic sequence unit.Amplitude,continuity and other seismic parameters are also used in the description of seismic sequence units.In the study area,six seismic sequences are divided and more than seven seismic facies are identified,including parallel-subparallel mat-shaped,foreset,wedge shaped,filling,lenticular,moundy and hummocky seismic facies,which show differentiation in spatial distribution and hereditability in vertical evolution.The sedimentary facies in the lake environment,including semideep-deep lake sub-facies,shallow lake and shore sub-facies,fan-delta,subaqueous alluvial fan,delta,turbidite,etc.The favorable areas are identified.
