摘　　要：采用特征参量法推导了低渗透油藏CO2驱相似准则,并分析了影响CO2驱效果和气窜的主要因素;在此基础上,建立了CO2驱气窜模糊评判预测模型,并进行了实际应用,验证了本文模型的准确性和有效性。A method of characteristic parameters was used to derive the similarity criterion for CO2 flood-ing in low-permeability oil reservoirs, and the factors to control CO2 flooding effects and gas channeling were analyzed. On this basis, a model of fuzzy evaluation prediction was built for gas channeling during CO2 flooding, and its actual application has verified its accuracy and effectiveness.
