摘　　要：根据20余口岩心和200多口开发井资料,从物源、高分辨率层序地层对比、岩石组构、粒度、沉积构造、砂体形态等方面研究的基础上,综合确认石南21井区头屯河组砂体为一曲流河-三角洲前缘沉积体系,水下分流河道微相是其优势相。该油藏的西北部区域具有一定的扩边能力,是下一步开发的重点。In this paper,according to more than 20 core and 200 developments-well data,from the aspect of the depositional sources,high resolution stratigraphic sequence correlation,the structure of rock,size,sedimentary structure,appearance of sandbody,etc.It is considered that the sandbody of Toutunhe formation in shinan 21 wellblock is sedimentary system of meandering river-delta,and submerged distributry channel microfacies is the major reservoir.Northwest of the reservoir has the ability to expand,which is the focal point of the next development.
