摘　　要：莺歌海盆地的每一个气田或含气构造均与底辟有着直接或间接的联系,底辟是其成藏的主控因素.对莺歌海盆地的昌南6-1和乐东22-1底辟的多期活动过程分析后认为,底辟活动对不同类型底辟的含气性的影响不同,此认识对底辟区的油气勘探具有一定的意义.The gas fields and gas-bearing structures in the Yinggehai Basin are controlled by diapir, which is the major factor for natural gas accumulation. The multiple movements of diapir in the basin have been noted by previous researchers. However, effective proof was not provided. This article analyzes the multiple movements of Changnan6-1 and Ledong22-1 diapirs. It is revealed that the multiple movements evidently affect the nature gas accumulation of different kinds of diapirs. The result is significant for future exploration in the diapir zone.
