| 摘 要： | 通过对孤北-桩海地区沙河街组的岩心观察、地震剖面解释、测井资料分析，研究了沙河街组层序划分和特征，划分出了3个长期旋回和6个中期旋回。在层序划分的基础上，进行了全区的地层格架的建立及层序充填，从中可以看出各层序在不同地区发育程度不同，这是由于古地理背景、后期构造抬升和剥蚀程度的不同造成的，不同时期的中期旋回在不同地区的发育特征不同。从层序充填上，从湖盆边缘到中央充填了一套砂砾岩一深湖泥岩，层序演化上从SQ1-SQ4-SQ6为一套具有砂砾结构的冲积扇-三角洲-湖泊-三角洲的充填旋回。

| Abstract: | Based on core observation,interpretation of seismic profiles and analysis of well logging of Shahejie formation in Gubei-Zhuanghai area is conducted the sequence division and summarization of the characteristics.Three long term cycles and 6 medium term cycles are outlined and the stratigraphic frame of the whole area is set up and the sequence filled on basis of the division which shows various development of each sequence in different areas.The difference is caused by various paleo-geographic background an... |
