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。
Based on the actual development data and fluid property data of the first and the northern part of Daqing Oilfield, as well as the material balance principle, the oil production rate, the liquid production rate, the accumulated water production and the accumulated underground production fluid, Relationship between the amount of oil and the cumulative effective amount of water. At the same time, the maximum theoretical oil recovery rate of the two zones is obtained, and it is pointed out that the change rate of oil production rate to the production rate decreases with the increase of the production rate due to the increase of water cut rate year by year. The method provided in this paper can be used to predict future reservoir development in these zones.
