深县凹陷沙一下段沉积体系恢复方法
|
摘要
以冀中坳陷深县凹陷沙一段为例,研究古地貌对层序中沉积体系发育规律的影响。首先用层序地层学原理建立深县凹陷等时地层格架,再结合地震剖面上下切沟谷、古凸起等古地貌识别特征标志,利用残留厚度法与层位拉平方法对砂一段进行古地貌分析。在古地貌恢复的基础上,充分考虑古地形地貌对沉积体系的影响,结合含砂率、地震属性、地震相等特征恢复了深县凹陷沙一下段沉积体系。
By taking the eample of Sha-1 member in Shenxian sag of Jizhong depression,this paper made research on the impact of paleo-geomorphology on the development rules of sedimentary system of sequence stratigraphy.First,sequence stratigraphy meth od was used to set up isochronous straigraphy structure,and then based on incised valley,paleo-uplifts and other paleo-geomor phology identification features of seismic profiles,residual thickness method and horizon flattening method were used to analyze pa leo-geomorphology.Based on the restored paleo-geomorphology and fully considering of the impact of paleo-geomorphology on sedimentary system,and combined with sand ratio,seismic properties,seismic facies and other characteristics,this paper finally re covered sedimentary system of lower Sha-1 member in Shenxian sag.
