沧东凹陷沙河街组地震地层分析
|
摘要
利用地震资料及地质、钻井资料,对沧东凹陷沙河街组地震反射剖面进行了地震界面及地震层序划分,对其反射特征进行了较详细的描述。在进行地震相及沉积相划分和分析的基础上,对各层序的沉积特征进行了分析,这为该地区沉积盆地的油气生储盖特征提供了基础资料[1]。
A detailed analysis of the seismic interfaces and seismic sequences was performed on the seismic data acquired from Shahejie Formation in Cangdong depression. The results were verified by geologic, drilling, and seismic data collected from neighboring areas. Reflection configurations of the seismic sequences were discussed by the authors. Based on the classification of the seismic facies and analysis of sedimentary facies, we analyzed the sedimentary characteristics. The results are of great importance to the study of source-reservoir-cap rock association in the area.
