Abstract
Using the latest datum, the studying conclusion of Qikou sag of Dagang oilfield’s important faulting
belts such as the Cangdong faulting belt, the Haihe-Xingang faulting belt, the Binhai faulted nose
and the Cengbei fault terrace belt and their structural character are as follows: the Cangdong
faulting belt has obvious segmentation; different zones’ occurrence and displacement character
have obvious differences; the Haihe-Xingang faulting belt is a indo-china period in the mesozoic
beginning thrust faulting, formed by structural inversion in Cenozoic; the Binhai faulted nose is
