摘　　要：从构造与沉积的控制和响应关系角度,论述了渤海湾盆地歧口凹陷在构造格局、伸展构造样式两方面所表现出的构造自相似性;研究了在构造自相似性的影响和控制下,渤海湾盆地歧口凹陷的盆地构造活动和沉积充填之间的控制和响应关系。研究表明,歧口凹陷的沉积体系展布、沉积旋回等沉积特征也显示出自相似性。并进一步探讨了沉积特征的自相似性对盆地油气勘探研究的意义。Bohai Bay Basin and Qikou Sag had the characteristics of self-similarity. From the point of view of structural controlling and sedimentary response, the structural self-similarity in structural framework and extensional structural patterns in Qikou Sag of Bohai Bay Basin were firstly discussed. Secondly, the controlling and response between structural activities and sedimentary filling under the control of structural self-similarity were studied.The study proves that the sedimentary systems distribution and sedimentary cycle are also self-similar. Finally, this paper makes further discussion on the significance of sedimentary self-similarity to petroleum exploration.
