【摘要】 研究了涠西南凹陷流一段扇三角洲的沉积特征,包括颜色、粒级、结构、构造等沉积相特征以及地震反射特征。在此基础上,分析了扇三角洲沉积特征对隐蔽油气藏形成的控制作用,并对扇三角洲储层中隐蔽油气藏的类型和最可能的分布位置进行了预测。更多还原

【Abstract】 The fan delta features of Liu-1 Member in Weixinan sag are studied,including sedimentary facies(color,grain size,texture and structure) and seismic reflections.Based on these,the controls of fan delta features over subtle hydrocarbon reservoirs are analyzed,and the type and location of hydrocarbon reservoirs are predicted in the fan delta sequence.更多还原
