大庆油田的长垣油藏已进入高含水后期开采阶段，水油比急剧上升，油水分布情况和开发动态发生了重大的变化。为了认识油水渗流规律，从推导适合长垣油藏的水驱特征曲线公式和开发指标公式开始，对实际区块的含水上升率与含水率关系，含水率及含水上升率与采出程度关系，采油指数递减率与含水率关系，无因次采液、采油指数随含水率变化曲线加以分析，清楚地认识了油藏开采过程中油水微观渗流规律，为油田开发规律及开发模式研究提供指导意义。

The Changyuan Reservoir of Daqing Oilfield has entered the stage of high water cut,WOR rising sharply. Oil and water distribution and develop performance there have change greatly. For the knowledge of the oil and water fluid flow law, we derived the water flooding characteristic curve formula and development index for Changyuan Reservoir,and we study the actual block water cut rate and water ratio,water ratio and water cut rate with recovery degree,productivity index decrement and water ratio,relative fluid productivity index and productivity factor oil with the change of water cut trend. We clearly understand the oil and water seepage rule of the reservoirs in the process of exploiting,it provides some guidance for related development and research.
