摘　　要：老油田长期注水开发,在注入水的冲刷和水洗作用下,使得油田储层孔隙结构及填隙物含量均发生改变,必然造成储层渗流特征复杂多变。由于油水相渗实验结果主要从宏观角度反映储层渗流特征,无法从微观层面对储层情况进行描述,有必要将实验室油-水相渗和核磁共振两种实验方法相结合研究高含水期储层渗流特征,从宏观和微观角度出发,基于D油田密闭取心井,研究高含水期储层渗流特征,对老油田开发技术及方案调整具有重要意义。In the injection of water erosion and water washing,oil reservoir pore structure and the filling contents have occurred.So water reservoir flow characteristics of long-term development of old oil fields is complex.Since oil and water relative permeability results primarily reflect reservoir flow characteristics from a macro point of view,but it can’t reflect from the micro level of the reservoir.It is necessary to research percolation characteristics of high water cut reservoir combining oil-water relative permeability with nuclear magnetic resonance.From macro and micro perspective,we researched percolation characteristics of high water cut reservoir based on sealed coring wells of oil filed D,which have a significance on development technology and project adjustments.
