摘　　要：油田进入中高含水开发阶段后,仅凭静态连通资料不能够反映真实的油藏水驱方向,传统的动态连通性研究方法耗时长、成本高且操作烦琐,因而研究流体动态连通性的数学反演方法,对于特低渗水驱油藏具有重要意义。本文推导了反映井间动态连通性的多元线性回归模型,并在实际油藏中对该模型进行了应用,计算结果符合多种水驱前缘的动态监测结果,且加密区的计算结果与水淹层的解释结果吻合,验证了模型的准确性和可行性。The static state connectivity could not reflect the real water direction after the oilfield entered the development phase of high water cut.Traditional research methods of dynamic connectivity have the limitations of long time consuming,high cost and complex operations,therefore,the mathematical inversion method for the study of dynamic connectivity has great significance in ultra-low permeability reservoirs.This paper derived the multiple linear regression model and the model has been applied to the actual reservoir.The calculation results conformed to the water flooded layer interpretation and the dynamic monitoring results of the waterflooding front,and the accuracy and feasibility of the mode has been verified.
