摘　　要：井间动态连通性是指储层内流体的连通性,与地层对比和地震横向预测的静态连通性有本质的区别。利用生产数据来研究油藏动态连通性,既能得到较准确有效的结果,又廉价易行。采用井场动态生产数据,使用灰色关联分析法,计算井间动态数据的相关性,通过相关性大小定量判断井间动态连通性的强弱和水驱油效果的好坏。结果表明:灰相关能对井间的连通性进行量化评价,并能够评价水驱效果。The connectivity of fluid between the reservior, that＇ s called inter-well dynamic connectivity, there is a difference with static connectivity by formation correlation and seismic lateral prediction. Using production data to study the dynamic connectivity of reservior, not only can get a more accurate and effective results, but also chea- per and easier. Based on the production performance data and the theory of grey relational analysis, correlation which characterizes the degree of inter-well connectivity and oil displacement efficiency can be obtained. It shows that the theory of grey relational analysis can evaluate inter-well dynamic connectivity quantitatively and oil dis- placement efficiency.
