深水成因沉积地震属性构型分析与模式探讨
|
摘要
以黄骅坳陷板桥凹陷古近系为例,通过对深水成因沉积及地震属性构型特征的研究,指出古地貌是影响深水沉积砂体的主要因素,深水河道的主河谷(或河道)基本上限定了深水复合河道的沉积,在主河道的两侧发育主堤岸、主漫滩,随着弯曲河道在主河谷内的摆动、迁移还伴生有次生堤岸、次生漫滩;水下重力流沉积一个最大的特点是受水下水道河谷地貌的影响,垂向加积是沉积的主体,侧向加积次之,在垂向加积的过程中,重力流不断发生沉积、侵蚀,再沉积、再侵蚀,而形成多重扭曲结构,这种沉积明显区别于曲流河道沉积。
In this paper,we discussed the Paleogene sedimentary sandstone body formed in deep-water conditions and architectural characteristics of seismic attributes in the Banqiao sag of Huanghua depression.The palaeogeomorphology is the dominant factor that affects the distribution of deep-water sandstone body,and the main river valley(or river) would limit the deposition of the sandstone body in the deep-water compound channel.The main bank and overbank is developed in both of main channel sides.With the bend river swinging and migrating in the main valley,the secondary bank and overbank was formed.The gravity flow deposition under deep water is controlled by the channel valley landforms,with main vertical aggradation and inferior lateral one.During the vertical aggradation process,the deposition,erosion,re-deposition and re-erosion occurs continuously for gravity flow sand body,causing the multiple distorted configuration of sandstone body in the semis profiles which distinguished from the meandering river deposition.
