摘　　要：针对文南油田沙二下亚段砂体变化快、微相类型多、河道宽度窄等地质特点,以区域沉积环境、沉积相研究为基础,沉积模式为指导,通过细分研究单元到单砂体,深化沉积微相研究,精细刻画窄河道砂体,建立窄河道砂体剩余油分布模式,提出相对应的合理挖潜模式,形成一套窄河道砂体精细刻画及剩余油评价技术,掌握油藏储量动用程度。In allusion of the characteristics of fast changes of sand bodies,multi-types of microfacies and narrow channel in Es_2~L of Wenan Oilfield,based on the sedimentary environment and sedimentary facies,by taking the sedimentary mode as guidance,the study units and single sand body were partitioned,the sedimentary microfacies study was optimized,a fine characterization of narrow channel sand bodies was carried out.The remaining oil distribution pattern of narrow channel sand bodies is established,a corresponding potential tapping mode is proposed,a set of technologies are established for fine description of narrow channel sand bodies and evaluation of remaining oil,thus the producing degree of reserves in the reservoir is improved.
