摘要(Abstract)：

本文基于大庆油田南一区和北一区的实际开发数据和地层流体性质资料，以及物质平衡原理，推导出稳产阶段的采油速度与采液速度，累积产水量与累积地下产液量，累积产油量与累积有效注水量等关系式。同时，得到这两个区的最大理论极限采油速度，并且指出，由于含水率逐年增加，采油速度对采液速度的变化率随采液速度的增加逐步减小。本文提供的方法，可以用于这些开发区的未来油藏动态预测。
Abstract In this paper, based on practical production data and reservoir fluid properties of the No.l South region and the No.l North region in Daqing oil field, as well as on material balance principle, we've derived some relationship such as withdrawal oil rate and withdrawal fluid rate at the stable production stage, cumulative water injection and cumulative subsurface fluid production; cumulative oil production and cumulative effective water injection, etc. Meanwhile we also have obtained the maximum theoretical critical withdrawal oil rate of the two regions and we've shown the fact that the ratio of withdrawal oil rate to withdrawal fluid rate decreases gradually, because of the continuous increase of water cut. The method described in the paper can be used to predict performance of these regions.
