摘　　要：探讨污水回注井最大注水量的预测方法,为安全高效的污水回注决策提供理论依据。在常规稳定渗流理论的基础上,利用实际的注水动态资料,考虑了回注污水对地层渗透率的损害,采用累加的思想来消除单次注水参数的偶然误差,推导建立了预测污水回注井最大注水量模型。在川中地区污水回注井中的运用表明,该模型能准确预测单井的最大注水量。The paper discusses the prediction method of the maximum water injection amount of water reinjection wells. This method can provide the decision-making theory for safe and efficient water reinjection. Based on the conventional stable seepage theory; considering the formation permeability damage of recycled produced water, using the information of the actual water injection dynamic, and adopting accumulation ideology to eliminate a single accidental error of injection parameters, the maximum water injection amount model is derived to predict the maximum water injection amount of reinjection wells. The model is successfully used for wastewater injection wells in the central Sichuan area. It shows that the model can accurately predict the maximum water injection amount of a single well.
