摘要
桩海地区是沾化和黄河口凹陷的结合部,特殊构造的位置造就了该区复杂的构造特征。本文在系统分析地震及钻井资料的基础上,着重研究了其走滑和挤压构造特征。初步研究表明:该区印支期以宽缓的褶皱为主要特征;燕山期发育大型走滑构造,伴有挤压构造;喜玛拉雅期以拉张和走滑构造运动为主,局部有挤压构造现象。
Zhuanghai area is located at the commissure between the Zhanhua sag and the Yellow River mouth sag, the special tectonic setting resulted in complex structural features of the area. Based on the systematically analyzed seismic and drilling data, the strike slip and compressional structure features are studied mainly in the paper; the primary research results show that the main feature is flat fold in Indo-Chinese epoch; A large strike slip structures with compressional structure were developed in Yanshan epoch; extensional and strike slip structure movements were developed mainly in Hinalayan epoch, compressional structures were developed locally also.
