摘要: 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。

Abstract: Diapir structure is a kind of important petroliferous structural styles.Based on the seismic data,the salt and mud diapirs in the offshore Bohai Bay Basin are analyzed,and the result shows that the salt and mud diapirs have various geometries and formation mechanisms,and have also exerted important influences on hydrocarbon accumulation.The shapes of salt diapirs change in different areas,and their associated structures styles involve the salt-withdrawal mini-basins,turtle structures and abundant normal faults.The key factors governing the development of salt diapirs are the gravitational gliding and the dextral strike-slipping movement of the Tan-Lu Fault.However,the mud diapirs have almost no change of shapes,and are controlled by the strike-slipping and reverse movements of the Tan-Lu Fault.The structural and subtle traps induced by the diapirs should be the favorable objectives for oil and gas exploration in the offshore Bohai Bay Basin

Key words: offshore Bohai Bay Basin, salt diapir, mud diapir, diapirism, hydrocarbon accumulation
