摘要： 储集层精细描述是老区挖潜、提高采收率的基础，也是已开发油田稳产的关键。由于缺乏资料和地质解释本身的多解性，储集层精细描述中单砂体连通性及规模评价往往存在不确定性。针对这一问题，应用高分辨率层序地层学分析方法，通过综合资料的分析对比，建立等时地层格架及砂体叠置模式，有效指导储集层描述和单砂体精细解剖。以吉林油田黑59区块注气储集层为例，进行储集层精细描述和单砂体精细解剖，明确了储集层纵、横向分布规律，刻画了单一成因砂体发育期次、规模等特征，实现了单砂体分布在三维空间的可视化。

Abstract: Fine reservoir description is the basis and key for later exploration and EOR as well as keeping stable production of an aged oilfield. However, there exist uncertainties in study of single sand body connectivity and scale during fine reservoir description, due to lack of data and multiple solutions of geological interpretation. This paper developed the isochronous stratigraphic frameworks and sands overlap model by using high?resolution sequence stratigrphy method and analysis and correlation of comprehensive data to effectively guide the reservoir description and the single sand body anatomy. Taking the gas injected reservoir in Hei?59 block in Jilin oilfield as an example, the fine reservoir description and single sand body detailed anatomy have determined the vertical and lateral distribution of the reservoir, described the development stages and scale of single sand body, and realized the 3D visualization distribution of the sand bodies in this area
