摘要(Abstract)：

沙三下亚段是马寨油田卫95块的主要含油层系,钻井资料显示储层厚度大、砂体成因复杂、相带认识难度大.为了研究卫95块沙三下亚段的沉积特征及沉积模式,根据地质学及沉积学理论,分析其泥岩颜色、岩石类型及组合、粒度特征、构造特征及沉积相.结果表明:位于东濮凹陷西北端第三断阶带的马寨油田卫95块发育扇三角洲前缘亚相,物源主要来自于西部的内黄隆起;该亚相又进一步识别出水下分流河道、水下分流河道侧翼、席状砂和水下分流河道间等4种微相,各主力砂组发育多期扇三角洲沉积,各扇体相互叠置,呈北西—南东向展布;亚相以水下分流河道和席状砂微相为主,其余微相次之.在区域构造背景的基础上,结合扇体的物源方向及时空展布特征,总结卫95块的沉积微相模式,为油田开发提供参考.

关键词(KeyWords)：东濮凹陷;马寨油田;卫95块;沙三下亚段;扇三角洲;沉积微相;沉积相模式
