库车坳陷克拉苏构造带盐下差异构造变形特征及控制因素
|
摘要
以研究区连片三维地震精细构造解释为基础,应用最新钻探成果,借鉴物理模拟实验的成果与认识,提出了克拉苏构造带盐下构造具有差异构造变形的特点,主要表现在:①自北向南,以克深断裂为界,断裂上盘以基底卷入构造变形为主,断裂下盘以滑脱构造变形为主,其中基底卷入变形带向东北收敛;②东西向构造模式存在明显差异,大北段受基底先存古隆起影响多发育基底卷入式构造,克深1-2段则以滑脱构造为主;③基底结构、膏盐岩层分布、多期叠加构造变形是控制盐下差异构造变形的主要因素。中生代基底结构变化控制盐下基底卷入与盖层滑脱2类构造模式的分布,膏盐层的差异分布及叠加构造变形影响了各构造段缩短量、变形样式的差异。
Based on the fine structure interpretation of 3D seismic data,latest drilling data and physical simulation experiments,research on the differential structural deformation in subsalt layer of Kelasu structural belt has been carried out.The result shows that:(1) Kelasu structural belt can be divided into two parts from north to south,which are basement involved belt at the hangingwal of Kelasu fault and detachment structure belt at the footwall of Kelasu fault.The basement involved belt was convergent toward the northeast direction;(2)The deformation style was differential in east-west direction.Dabei segment mainly formed basement involved structures which are controlled by the pre-existing paleo-uplift and Keshen1-2 segment mainly formed detachment structure;(3) The main controlling factors of differential structure deformation are the basement structure,distribution of evaporate layer and the multi-stage superposition of tectonic deformation.The difference of basement configuration controlled the distribution of basement structures and detachment structures.Evaporate layer and multi-stage superposition of tectonic deformation influenced the shorten amount and structural deformation.
