| 摘 要： | 钻井资料的缺少限制了对沧东凹陷孔一段构造与沉积的关系研究。利用地震属性技术，结合测井数据和三维地震剖面，对沧东凹陷孔一段构造与沉积特征进行分析与解释，结果表明：孔店凸起、沧东断层和火山作用是影响孔一期沧东凹陷演化的主要构造活动。其中，前两者直接控制着凹陷的发展。受构造活动影响，缓坡带与陡坡带2种构造样式存在于凹陷东西两侧．凹陷内部构成了3个沉积区：缓坡带沉积区、陡坡带沉积区及凹陷沉降中心沉积区。缓坡带主要沉积辫状河三角洲．砂体类型主要为辫状河道、河口砂坝沉积；陡坡带主要发育冲积扇和扇三角洲，砂体类型主要有扇体上发育的河道沉积及河口砂坝沉积：凹陷沉降中心是半深湖-深湖相沉积。沧东断层与孔店凸起是孔一期沧东凹陷构造演化的主控因素。更是控制凹陷沉积环境与沉积相类型及砂体空间展布特征的决定性因素。

| Abstract: | Due to the few drilling data,the research on the characteristics and relationships between Ek_1 sedimentary and structure in Cangdong Sag is limited.Using the seismic attributes technology,and combining with the logging data and three-dimensional seismic profiles,the structure and sedimentary characteristics are analyzed and interpreted.The results show that the tectonic evolution of Cangdong Sag is mainly affected by Kongdian Arch,Cangdong Fault and volcanism,especially the former two ones which directly c... |
