摘要
在构造演化、井震结合、二维地震资料精细解释的基础上,分析沁水盆地晋中区块断裂特征。通过工区断裂分布及组合、构造背景及演化,确定主干断层,将晋中区块划分为晋中断陷、太谷斜坡、太谷凸起、榆社斜坡、武乡凹陷五个构造单元。编制并研究构造图,分析圈闭要素。综合研究后认为,工区内成藏的有利区带在榆社斜坡构造带上,为盆地后续的勘探开发工作提供借鉴。
Based on the analysis of tectonic evolution,borehole combination and two-dimensional seismic data,the fracture characteristics of Jinzhong block in Qinshui basin are analyzed.Through the fault distribution and combination,tectonic setting and evolution,the main faults are identified.From which the Jinzhong blocks are divided into five tectonic units,namely,Jinzhong fault depression,Taigu slope,Taigu uplift,Yushe slope and Wuxiang depression.Then,compiling and studying the structural drawing and analyzing the trap elements are conducted.After comprehensive research,it is considered that the favorable zone in the work area is on the Yushe slope tectonic belt,which provides the basis for the subsequent exploration and development of the basin.
