摘要
莺歌海盆地的泥 -流体底辟构造发育演化是区域构造应力场变化和超压体系形成演化的结果。与盆地构造类型密切相关的不均衡压实和热作用引起盆地超压体系的发育 ,而区域构造应力场变化则导致盆地中中新世以泥底辟作用为主 ,晚中新世—第四纪以流体底辟作用为主 ,其中 ,早期泥底辟阶段形成的构造形态对晚期流体底辟作用有显著的控制作用。在莺歌海组浅层底辟圈闭中 。
The evolution of mud-fluid diapir in Yinggehai Basin is the result of regional stress field variation and (over-pressure) system formation and evolution. Development of the over-pressure system is caused by disequilibrium compaction and thermal evolution that are intimately related to the structural styles of the basin. Variation of the regional stress field resulted in the mud-diapirism in mid-Miocene and the fluid diapirism in late Miocene to Quaternary. The structures formed during the early mud-diapirism stage obviously controlled the later stage fluid diapirism. For the shallow traps in Yinggehai Formation, the main reason for episodic injection of fluid with different gas components is the matching of trap formation and hydrocarbon generation in Miocene.
