摘    要:综合利用地震、测井、岩心等资料,对塔南凹陷南屯组近岸水下扇的沉积特征、展布、演化及有利含油相带进行研究。结果表明:本区近岸水下扇可识别出3种亚相、4种微相,不同相带间沉积特征差异显著;近岸水下扇集中发育于凹陷东部控盆断裂的下降盘,在多期扇体叠置连片下,形成了东南、东北两套扇裙,其展布、演化具有南北各自连片,扇裙先盛后衰的特点,但受控盆断裂幕式活动和东南、东北物源供给差异的影响,东南扇群的发展和消亡均略早于东北扇群;中扇辫状沟道储层物性及含油气性最好,主要发育中低孔储层,但不同位置及埋深储层渗透率差异较大,很难形成大面积连片的优质储层,因此本区近岸水下扇沉积主要发育个体规模相对较小却数量众多的岩性油气藏和构造-岩性复合油气藏。

关 键 词:塔南凹陷  南屯组  近岸水下扇  沉积特征  展布演化特征  有利含油相带

Abstract:The sedimentary characteristics,distribution,evolution and favorable oil-bearing facies belts of near-shore subaqueous fan of Nantun formation in Tanan depression were studied through the integrated utilization of data of seismology,well-logging and core.The results show that three kinds of sub-facies and four kinds of microfacies can be identified in near-shore subaqueous fan,and the different facies belts show obvious distinctions in sedimentary characteristics.The development of near-shore subaqueous fan...
Keywords:Tanna depression  Nantun formation  near-shore subaqueous fan  sedimentary characteristics  characteristics of distribution and evolution  favorable oil-bearing facies belts
