十三间房探区滑脱构造的特征及形成演化
|
摘要
为了研究十三间房探区构造特征,利用地质及钻井资料,对研究区地震剖面进行精细构造解释。在分析该区两大局部构造(七克台构造和房1井背斜)及撕裂断层特点的基础上,认为滑脱因素在其构造形成过程中起主导作用。通过划分出房1井背斜和七克台构造的生长地层得知,构造的形成北早南晚。同时,识别出房1井背斜生长地层的变形方式为生长三角楔和倾斜扇,进而确定该背斜形成机制为膝折带迁移和翼部旋转联合作用。最后建立起研究区整体构造形成的三期滑动模型,这对研究区的构造解释及油气成藏都有重要的意义。
In order to analyze the structures in 13- Room- area,this paper made fine structural interpretation for all available seismic profile. Based on the in- deep analysis of two local structures( Qiketai structure and No. 1 room well anticline) and tear fault,it put forward that slip factor plays the leading role in the process of structure formation. According to the growth strata of Qiketai structure and No. 1 room well anticline,the time that both structures formed is displayed. Deformation mode of growth strata presents triangle wedge and inclined fan,which reveals forming mechanism of the anticline owing to the combined effect of Limb rotation and kink- band migration. Then Three stages slip- mode is established,which is of great importance for studying tectonic evolution and hydrocarbon accumulation.
