| 摘 要： | 运用层序地层及沉积相理论对大民屯凹陷西斜坡古近纪沙三段发育的沉积特征进行分析,结果表明:沙三段发育低位、湖侵、高位体系域;大民屯凹陷西斜坡沙三段的沉积相类型可分为冲积扇相、辫状河三角洲相和浊积扇相;前进断裂坡折带控制了大民屯凹陷西斜坡沙三段沉积发育,低位域主要发育冲积扇、辫状河三角洲、滑塌浊积扇,同沉积断裂坡折带之下发育辫状河三角洲、滑塌浊积扇,湖侵域在坡折带之下主要发育滑塌浊积扇、湖相泥岩;高位域西斜坡主要发育冲积扇和辫状河三角洲相沉积,从而沿着西斜坡形成冲积扇相—三角洲相—浊积扇相的沉积模式;沙三中下段,大民屯凹陷荣胜堡洼陷东北斜坡部位受前进断裂破折带控制的沉积砂体及浅湖-半深湖区的浊积扇砂体是形成岩性油气藏有利区带。

| Abstract: | Based on the theory of stratigraphy and sedimentary facies,the sedimentary feature of Es3 Member in the western slope of Damintun Depression has been analyzed.The Damintun Depression develops lower stand system tract,transgressive system tract and high stand system tract.Sedimentary facies in Es3 Member in the western slope of Damintun Depression can be divided into alluvial fan,braided river fan-delta and turbidite fan respectively.Sediments in different tract of Es3 Member in Rongshengbao sag is controlled by Qianjin fault slope zone.Alluvial fan,braided river fan-delta and turbidite fan are recognized in lower stand system tract and braided river fan-delta and turbidite fan are found below the fault slope zone.Deep lake mudstone and turbidite fan mainly develop below the fault slope zone in transgressive system tract.Alluvial fan and braided river fan-delta form along the western slope of Rongshnegbao sag.So,the sedimentary model of alluvial fan-braided river fan-delta-turbidite fan is generated in Es3 Member in the western slope of Damintun Depression.Profitable lithologic reservoir occurs in the sedimentary sand controlled by Qianjin fault slope zone and in the turbidite sand in shallow-deep lake of Es3 Member in the western slop of Damintun Depresion. |
