| 中文摘要: |
| 以层序地层学理论为指导,利用岩心、测井、地震资料相结合的分析手段,建立了苏德尔特构造带贝14块兴安岭群的层序地层等时格架,将兴安岭群划分为3个三级层序和短期中期基准面旋回.分析了个层序的主要构型及其成因,认为盆地由断陷向凹陷转化,沉积速率也随之降低,盆地各层序的厚度由厚变薄.兴安岭群内部层序界面多为沉积间断,不同沉积时期的岩性、物性以及沉积物叠置关系具有明显的韵律性变化.层序发育明显受构造活动的控制,幕式构造活动是构成层序主要构型的成因. |

| Guided by sequential stratigrphy theory data from core observation,well logging and seismic survey are used to draw up the isotime configure of sequential stratigraphy of Bei 14 block of Xinganling group.Xinganling group is divided into 3 3rd sequences and short term,intermediate term datum cycles.Analysis of main structural configuration and genesis of the sequences shows that the basin changes from faulted depression to depression with decreased sedimentation rate and thinning of the sequences.Interfaces within Xinganling group are often sedimentary breaks.Lithology,physical property,and juxtaposition of rocks deposited in different times are of clear rhyme change.Development of sequences is controlled by tectonic activity and episodic tectonism leads to the main sequential configuration. |
