摘　　要：针对深水浊积砂岩油田开发指标预测难度大的问题,以西非尼日尔三角洲盆地Akpo油田地震、地质及生产动态资料为基础,从机理上分析了动态、静态相渗差异的根本原因,引入水相运动系数定量评价动态相渗与油水宏观运动之间的关系;通过动态相渗研究建立储层连通程度及非均质性等因素与生产动态之间的相关性,形成一套针对深水浊积砂岩油田的动态相渗分析及应用方法。研究结果表明:深水浊积砂岩油田油水运动规律受储层连通性及非均质性影响显著;动态相渗规律综合反映了储层中油水的宏观运动规律,用于生产动态分析更加合理;研究方法充分考虑储层因素的影响,预测精度高,实用性强,对深水开发具有指导意义。Based on the seismic data,geology and production history of Akpo Oilfield in the Niger Delta Basin of west Africa,the mechanism difference in dynamic and static relative-permeabilities were analyzed to improve the development indicator prediction for the deepwater turbidite sandstone oilfield.The water motion coefficient was introduced to quantitatively evaluate the relationship between dynamic relative-permeability and macroscopic oil-water flowing.The correlations between production performance and reservoir connectivity and heterogeneity were established on the basis of dynamic relative-permeability analysis.A set of dynamic relative-permeability analysis and application method was proposed for the deepwater turbidite sandstone oilfield.Research indicates that The oil-water flowing in the deepwater turbidite oilfield is greatly dependent on the reservoir connectivity and heterogeneity.The dynamic relative-permeability performance reflects the macroscopic oil-water flowing pattern in the reservoir,which is more reasonable in production performance analysis.This research with high prediction accuracy and practicability fully considers the influencing of reservoir properties,which could provide certain guidance for the deepwater reservoir development.
