摘　　要：应用注水模拟实验、环境扫描电镜、水淹层测井解释等研究技术,分析了储层参数变化机理,较全面地分析了高含水期的高孔高渗油藏、中孔中渗油藏和稠油油藏注水后储层结构的变化规律,并将研究成果应用于水淹层测井解释、地质模型的重新修订、数值模拟调参、剩余油分布预测和油层防砂等方面,取得了较好的效果。本项研究可为类似油田的开发提供一定的借鉴。By using technologies of water injection modeling experiment, scanning electron microscope and log interpretation of water flooded zone, this paper analyzes the mechanism of reservoir parameter change, and the change of reservoir structures after water injection in high porosity and permeability reservoir, medium porosity and permeability reservoir and heavy oil reservoir in high water-cut stage. The result of this study has been successfully applied to log interpretation of water flooded zone, correction of geological model, parameter adjustment for numerical simulation, prediction of residual oil distribution, and sand control. This study provides reference to the development of similar oilfield.
