除了构造信息之外,在地震剖面中,还蕴藏着大量地层和沉积特征方面的信息.充分利用这些信息,解释它们所代表的地层学和沉积学意义,有助于在井数很少的情况下正确地划分地层,识别沉积环境,建立沉积体系,推测有利的含油气地带.此外,地震地层学方法把地层和构造两方面的特征天然地结合起来,对于解释盆地的形成和发育机制,有着重大意义.作者利用地震地层学方法,对黄骅拗陷下第三系沉积环境中的几个基本问题重新加以认识.其主要结果是;1.明确了各层组间的接触关系,调整了某些层组的界线;2.半定量地计算了始新世——渐新世海平面升降变化;3.通过古水流方向分析,明确了板桥及唐家河地区东营组、沙一段及沙二段三角洲的物源;4.山麓型冲积扇三角洲是本区主要的骨架沉积相,而重力滑动所引起的滚卷背斜和刺穿构造则是本区重要构造特征.
In addition to the tectonic information, there is a wealth of information on the properties of stratigraphy and sediments in the seismic section, making use of this information to explain the stratigraphic and sedimentological implications they represent, which is useful in situations where the number of wells is small In addition, the seismic stratigraphy method naturally combines the features of both stratigraphy and tectonics to explain the formation and development mechanism of the basin, and has the following features Great significance.The author uses the method of seismic stratigraphy to re-understand several basic problems in the sedimentary environment of the Tertiary in the Huanghua Depression.The main results are as follows: 1. The contact relationship between the strata is clarified and some The boundaries of these layers; 2. The Eocene-Oligocene sea level fluctuation has been semi-quantitatively calculated; 3.According to the paleo-water flow direction analysis, it is clear that the Dongying Formation, Delta source; 4. Piedmont alluvial fan delta is the main skeleton sedimentary facies in this area, and the rolling anticline and piercing structure caused by gravity sliding are the important tectonic features in this area.
