摘要： 为揭示渤南洼陷沙四上亚段沉积相的分布规律，明确勘探方向，依据岩心、测井、录井、分析化验及地震资料，运用沉积学和储集层地质学理论，在该段划分出4种沉积相：扇三角洲相、近岸水下扇相、滩坝相和湖泊相。并根据层序划分结果，对各体系域的沉积相展布特征进行了探讨。通过对分析化验数据的归纳、总结，明确了8个有利储集体：罗家鼻状构造带砂岩滩坝、缓坡带扇三角洲前缘、义东断裂带生物礁、缓坡带砂质灰岩滩坝、缓坡带灰岩滩坝、陡坡带扇三角洲前缘、缓坡带扇三角洲平原以及缓坡带前扇三角洲，在此基础上预测出4个有利勘探区，即陡坡带扇三角洲前缘区、义东断裂带生物礁区、罗家鼻状构造带砂岩滩坝区及缓坡带扇三角洲—灰岩滩坝—砂质灰岩滩坝混合区。

Abstract: Based on the core, logging, lab testing and seismic data, by means of theory of sedimentology and reservoir geology, four sedimentary facies are classified in the upper part of fourth member of Shahejie formation in Bonan sag as fan delta facies, near?shore subaqueous fan facies, beach bar facies and lake facies, their distributions of each system tract are discussed, and eight favorable reservoir bodies are ascertained, such as sandstone beach bar in Luojia nose?like structural belt, fan delta front in the ramp belt, reef in Yidong fault belt, sandy limestone beach bar in the ramp belt, limestone beach bar in the ramp belt, fan delta front in the steep slope belt, fan delta plain in the ramp belt and fan prodelta in the ramp belt. Based on these, four favorable areas are predicted, they are the fan delta front area in the steep slope belt, the reef area in Yidong fault belt, the sandstone beach bar area in Luojia nose?like structrual belt, and the mixing areas of fan delta-limestone beach bar-sandy limestone beach bar in the ramp belt
