| 摘 要： | 综合运用岩心、钻井、测井及地震资料，对潍北凹陷古近系孔一段的地层特征及沉积演化进行研究。结果表明：潍北凹陷孔店组一段可以划分为3个亚段、11个砂层组。在西部鄌郚—葛沟断裂和东部昌邑—大店断裂控制下，地层东西向发育稳定，仅在北部洼陷带地层显著加厚；在北部古城—潍河口断层控制下，地层向南部超覆，地层由北向南变薄。潍北凹陷孔店组一段主要发育扇三角洲相和湖泊相，南部斜坡带发育小范围三角洲相。孔一下亚段，物源供给充足，北部洼陷带、瓦城断阶带和灶户断鼻带发育大规模的扇三角洲相；孔一中亚段，湖盆水体变浅，物源供给减少，北部洼陷带、瓦城断阶带和灶户断鼻带继承性发育扇三角洲相，但分布范围变小；孔一上亚段，湖盆水体最浅，物源供给少，全区发育滨浅湖亚相，仅在央斜4井区和昌11井区发育小范围的扇三角洲相沉积。

| Abstract: | Based on the comprehensive analysis of cores， drilling well，logging and seismic data，the stratigraphic characteristics and sedimentary evolution in the Member 1 of Paleogene Kongdian Formation in Weibei Sag was analyzed.This study suggests that the Member 1 of Kongdian Formation was divided into 3 sub-members，containing 11 sand sets.Controlled by Tangwu-Gegou fault in the west and Changyi-Dadian fault in the east，the strata developed stably in the east and west，only in the northern sub-sag belt strata became thicker.Controlled by Gucheng-Weihekou fault in the northern Weibei Sag，the strata overlapped towards the south and thinned generally from north to south.Fan delta facies and lacustrine facies mainly developed in Member 1 of Kongdian Formation in Weibei Sag，and delta developed in small scale in the southern slope belt.During the development of the lower submember of Member 1 of Kongdian Formation，sediment supply was abundant，which formed the large-scale fan-deltas in northern sub-sag belt，Wacheng fault-step belt and Zaohu fault-nose belt.During the development of the middle submember of Member 1 of Kongdian Formation，the depth of water became shallower and sediment supply decreased，fan-deltas inherited the development in northern sub-sag belt，Wacheng fault-step belt and Zaohu fault-nose belt，which distributed in small scale.During the development of the upper submember of Member 1 of Kongdian Formation，the depth of water became the shallowest，the whole area developed shore-shallow lacustrine facies，and only small-scale fan-deltas developed in Wells Yangxie 4 and Chang 11. |
