摘　　要：以永北地区砂、砾岩油藏的勘探开发为例 ,以井点分析为基础 ,综合应用地震、测井、地质和试油试采等资料 ,对主要含油层系沙四～沙三段砂、砾岩体进行整体解剖和综合分析。通过高分辨层序地层研究 ,建立了沙四～沙三段层序地层单元格架 ,揭示了砂、砾岩体成因类型及其内部结构 ;应用油气成藏系统理论开展油气成藏体系研究 ,确定了油气藏类型、控制因素及空间展布规律 ,建立了符合本区的砂、砾岩体油气成藏模式 ;最后总结出本区沙四～沙三段砂、砾岩体油藏分布规律 ,并选择有利目标进行滚动勘探开发 ,取得了较好的效果。With exploration and development of glutenite reservoir in Yongbei area as the case, applying seismic, logging, geology and testing information comprehensively, glutenite sections of Sha 4 and Sha 3 formations are reviewed and analyzed from well point analysis. Sequence stratigraphic units grid of Sha3 to Sha 4 formation is established through sequence stratigraphy high resolution study. As such, forming reasons, types and its internal structure of glutenite rock body are revealed. Besides, reservoir type,controlling factor and spacial distribution regularities are determined with reservoir forming system study by applying related theories. In due course, glutenite reservoir forming patterns in the subject area have been established and distribution regularities summarized, which are also beneficial for the progressive exploration and development of favorable targets.
