| 摘 要： | 以高分辨率层序地层学原理为指导,利用测井、岩芯和录井等资料,对车镇凹陷上古生界不同级次基准面旋回进行了高分辨率层序划分。将上古生界划分为2个超长期、7个长期、16个中期和45个短期基准面旋回,精细对比研究了短期、中期和长期基准面旋回。其中,短期基准面旋回可分为2大类3种亚类,并区别出A型、B型不对称短期基准面旋回和C型对称性短期基准面旋回,总结了它们的结构特征、形成条件、岩性岩相组成;通过研究不同沉积体系下中期、长期基准面旋回特点,得出中期、长期基准面旋回的特点和发育特征,区别出不同沉积环境下层序界面特点;分析了研究区内超长期基准面旋回特征,综合分析认为车镇凹陷超长期基准面旋回以下降半旋回为主。 |

| Abstract: | Based on the principles of high resolution sequence stratigraphy utilizing,with the data of well logging,and core etcdata,different kinds of base level cycles of in the Upper Paleozoic in of the Chezhen Sag are dividedrecognized.Then two super long-terms,seven long-terms,sixteen middle-terms and forty-five short-terms base level cycles are identified.divided from the Upper Paleozoic and balanced greatly.There are two types and kinds(three subtypes second kinds) short-term base level cycles in the researching area,including.Distinguish the asymmetrical base level cycles(A and B) and symmetry symmetrical base level cycles(C),and generalize the Their structure structural,genetic,lithological,and facies features are discussed,formatting conditions,rock characters and rock facies constitution.Further analyzing Through the analysis of the middle-term and long-term base level cycles in the characteristics of different sedimentary depositional systems base level cycles,their get the structural and development characteristics are summarized of middle-term and long-term base level,and distinguish the strata sequence base level features under different sedimentary circumstances.Analysis of make a research on the cycle features of super long-term base level cycles in the Paleozoic of the Chezhen Sag indicates that they are dominated.By the synthesis analyses,get the conclusion which is that Chezhen Sag super long-term base level is mainly falling half cycles. |
