摘要：
为揭示莺歌海盆地中央底辟带的底辟类型，重点研究了莺歌海盆地各种底辟的地震成像特点，依据底辟的物质构成和侵入方式，将莺歌海盆地的底辟分为缓慢挤入型、持续刺穿型、周期塌陷型及混合突破型。缓慢挤入型主要由砂、泥质组成，流体成分少，其物质具有高黏度、低塑性的特点，上侵相对滞缓; 持续刺穿型具有下部泥底辟和上部流体底辟的双元结构，具有高能量刺穿的持续性，泥和流体同步上侵，流体优先刺穿并渗入浅层; 周期塌陷型底辟超强能量刺穿初始地表，周期性释放后底辟口回抽沉积，超浅层沉积漏斗状; 混合突破型底辟为两种以上类型的组合，具有各组合类型的特点。 |

Abstract:
In order to reveal the diapiric types in central diapiric zone of Yinggehai Basin，seismic imaging characteristics in different diapirs of Yinggehai Basin were studied． According to the material compositions and incursion patterns，the diapirs can be divided into four types which include slow squeeze type，continuous puncture type，periodic collapse type and hybrid breakthrough type． The slow squeeze type is mainly composed of sand，mud and small amount of fluid，with high viscosity and low plasticity． The intrusion is relatively slow． The continuous puncture type has dual structure consisting of lower mud diapir and upper fluid diapir，with high-energy puncture continuity． The mud and fluid intruded simultaneously，the fluid preferentially pierced and penetrated the shallow layer． For the periodic collapse type，the diapir pierced the initial surface by its strong energy，the diapir mouth then pumped back to deposit after the energy releases periodically，and the shallow sedimentary deposits were shaped like a funnel． The hybrid breakthrough type is a combination of at least two of the above mentioned diapiric types，with mixed characteristics． |
