摘要
厚油层层内非均质是二次开发储层精细描述的重点。以大港油区二次开发先导区羊三木油田为例,在单砂层级地层精细对比及沉积微相研究基础上,对厚油层进行细分研究。重点识别层内夹层,采用储层构型分析的思路,建立厚油层细分三维地质模型,将厚砂层分为多个相对独立的流动单元,并利用水淹层解释、剩余油饱和度监测井等手段,描述厚油层层内剩余油分布。
The heterogeneity of the thick reservoir is the key point in the detailed reservoir description at the stage of the secondary development. Taking the Yangsanmu Oilfield, the pilot test area of Dagang petroliferous province, as an example, the thick reservoir is subdivided based on the fine strata correlation and the study on sedimentary microfacies. The interlayer of the thick reservoir is identified, its 3D model is built and the thick reservoir is divided into relatively independent flow units acording to the architecture analysis. Then the remaining oil distribution is studied using the data of water flooded zones interpretation and oil saturation monitoring. They may serve as the geological foundation for the secondary development plan design.
