摘　　要：目前对于水驱油田注采比的确定方法较多,但各类方法计算过程较为复杂。因此基于注水开发油田注采关系及水驱特征曲线,得到水驱油田合理注采比与含水率关系式。此模型参数使用比较简单,模型中所需要的生产动态数据较少,且结果预测准确,适用于动静态参数相对较少的油田。利用该理论关系式,可以评价油田水驱开发效果,为目标油田的下一步开发调整提供理论支持。研究分析表明,利用丙型水驱特征曲线得到的注采比与实际值较吻合,应用效果较好。且实际值与理论值越接近,水驱开发效果就越好;否则油田需进行综合调整,以改善水驱开发效果。结合K油田实际生产动态数据,验证了该理论关系式的适用性和可靠性。At present,there are many methods for determining the injection production ratio of water drive oilfields,but the calculation process of various methods is relatively complex.Therefore,based on the injection production relationship and water drive characteristic curve of water injec-tion development oilfields,the reasonable injection production ratio and water content relationship formula of water drive oilfields are obtained.This model has relatively simple parameters to use,requires less production dynamic data in the model,and accurately predicts the results,making it suit-able for oil fields with relatively few dynamic and static parameters.By using this theoretical relationship,the effectiveness of oilfield water drive de-velopment can be evaluated,providing theoretical support for the next development adjustment of the target oilfield.Research analysis shows that the injection production ratio obtained by using the characteristic curve of type C water drive is in good agreement with the actual value,and the applica-tion effect is good.And the closer the actual value is to the theoretical value,the better the water drive development effect will be;Otherwise,the oil-field needs to undergo comprehensive adjustments to improve the effectiveness of water drive development.Combined with the actual production per-formance data of K oilfield,the applicability and reliability of the theoretical relationship are verified.
