摘要(Abstract)：

以海拉尔油田贝301区块为例,基于高分辨率层序地层学理论,对南屯组进行不同级次基准面旋回识别与划分,建立了高分辨率层序地层格架。开展砂体精细刻画,将南屯组三角洲前缘沉积复合砂体划分为多套沉积微相的单成因砂体,并建立单成因砂体组合模型。研究认为:沉积微相的空间展布及砂体的叠置方式会对水驱优势方向和注水强度产生影响,综合上述因素结合各区域水驱特征采取相应的开发策略,明显改善了油藏的整体开发效果。应用结果表明,该研究成果可以满足此类油田不同阶段生产动态分析及水驱调整的需要,为剩余油挖潜和开发综合调整提供地质依据。
Taking Block Bei 301 of Hailer Oilfield as an example,based on the theory of high-resolution sequence stratigraphy,Nantun Formation was identified and divided into different-grade datum-level cycles,and moreover the high-resolution sequence stratigraphic framework was established. The fine characterization of the sandbody was carried out and the sedimentary composite sandbody of Nantun-Formation delta front was divided into multiple sets of the sedimentary-microfacies single-genesis sandbodies,and furthermore the single-genesis sandbody combined model was built. The study shows that the spatial sedimentary-microfacies distribution and the sandbody superposition have impacts on the dominant direction of the waterflooding and the strength of waterflooding. By means of the above combined factors with the water flooding characteristics of each region,the corresponding development strategies were adopted,and the overall development effect of the oil reservoir was improved. The application results show that the research achievements can meet the needs of the production dynamic analysis and the waterflooding adjustment in different stages of such oilfields,and furthermore can provide the geological evidences for the re-mained oil tapping and the comprehensive adjustment of the development.
