摘　　要：缝洞型碳酸盐岩油藏储集空间复杂,呈现出很强的非均质性和多尺度特征,除个别井水驱特征曲线呈现出砂岩油藏特征或单一直线段特征外,其余井水驱特征曲线多呈现出多直线段台阶状或不规则特征,因此不能直接对传统水驱特征曲线进行简单的应用。在对国内外常用的50多条水驱特征曲线进行筛选的基础上,对桑南西缝洞型碳酸盐岩油藏水驱特征曲线进行了选择应用,分析结果表明,对于缝洞型碳酸盐岩油藏,需要根据分析应用情况的不同及与实际资料的相关性来选择应用水驱特征曲线。为了进一步完善缝洞型碳酸盐岩油藏水驱特征曲线的选择应用,在此基础上对其水驱特征曲线应用相关事项作了补充。Fractured-vuggy carbonate reservoir space are complex,showing very strong heterogeneous and multi-scale feature. Despite the fact that certain well water drive characteristic curves presen sandstone reservoir characteristics or single straight segment characteristics,much of the rest well water drive characteristic curves are step-like curve with segments of straight line or irregular features,so it is not justified to apply water drive characteristic curve into them without selection.In this paper,more than 50 water drive characteristic curves at home and abroad are screened,and water drive characteristic curve for Sangnan Western is selected for application.The analysis results show that the correlation of practical data and applications is the key consideration when applying water drive characteristic curve to fractured-vuggy carbonate reservoir.In order to further perfect the application of water drive characteristic curve of fractured-vuggy carbonate reservoir,the relevant matters of water drive characteristic curve application for fractured-vuggy carbonate reservoir are presented,too.
