渤海地区主要发育盐底辟和泥底辟,根据地震资料解释成果,对渤海地区的底辟构造及其伴生构造的几何形态特征与形成机制进行了分析,同时探讨了底辟构造与油气聚集成藏的关系。盐底辟外部形态变化较大,周缘伴生构造包括盐边凹陷、龟背构造和丰富的正断层等,盐底辟的形成演化主要受重力滑动作用和郯庐断裂带的走滑作用控制;泥底辟形态变化较小,主要受郯庐断裂带的走滑和反转作用控制。底辟作用形成的相关构造圈闭和隐蔽圈闭都是渤海地区值得关注的有利油气勘探目标。
Based on the results of seismic data interpretation, the characteristics of the diapir structure and its accompanying structures in the Bohai Sea are analyzed. At the same time, the relationship between the structure of the diapir and the hydrocarbon accumulation Hidden relationship. The changes of the external morphology of the salt diabases are large, and the associated structures of the periphery include salt margin depression, turtle structure and abundant normal faults. The formation and evolution of the salt diapir are mainly controlled by the gravitational sliding and the strike-slip effect of the Tanlu fault zone. The changes in the morphology of the diapirs are smaller, which are mainly controlled by the strike-slip and reverse effects of the Tan-Lu fault zone. Related structural traps and subtle traps formed by diapirism are both favorable targets for oil and gas exploration in the Bohai Sea area.
