摘要: 松辽盆地十屋断陷是一个西断东超型的箕状断陷盆地.通过岩心、录井、测井的综合研究,根据层序地层学原理,将十屋断陷划分出3个超层序和6个三级层序;识别出冲积扇、扇三角洲、辫状河三角洲、水下扇、滨浅湖、半深湖、深湖和水下重力流等几种沉积相类型.其中冲积扇、扇三角洲发育在断陷的西部陡坡带,东南缓坡带发育辫状河三角洲和浊积扇;中央凹陷带发育滨浅湖和半深湖、深湖相.研究表明十屋断陷经历过3次大的湖泛,层序在演化上具有早期形成、中晚期继承性发育到达鼎盛的特点.Abstract: The Shiwu Fault Depression is the one with faults in the west and overlap in the east in the Songliao Basin.Based on synthetic study of core,drilling and logging data,three super sequences and six third-order sequences were identified and several types of sedimentary facies were recognized in the depre-ssion.Among these sedimentary facies,alluvial fan and fan delta were deposited in the step slope in the west of the depression,braided river delta and turbidity fans in the ramp of the southeast,and half-deep and deep lake in the middle sag.It was indicated that the Shiwu Fault Depression underwent three times of lake transgression.The evolution of the sequences can be summarized as early formation stage,continuously developing stage and well developed stage.
