摘　　要：油田注采平衡状况关系到油藏有效驱替系统的建立,影响着油藏稳产情况及最终的累产。但是受边底水入侵及注入水外溢的影响,仅靠注采数据计算的注采比存在很大的误差。通过引入物质平衡方程推导出计算注采比的新方法,并在16个注采单元进行应用,计算结果证明该方法精确可靠。The balance between Oilfield injection and production is related to the establishment of effective displacement reservoir system, and the stable production situation of oil reservoir and ultimately total production are also influenced. By the edge and bottom water intrusion and spillover effects of the injected water, there is a big error that injection - production ratio calculated only depends on injection and pro-duction data. A new method to calculate injection - production ratio is introduced, namely Material Balance Equation, which is applied to 16 injection and production units of branch corporation. The results show that this method is accurate and reliable.
