摘　　要：影响渗吸采收率的因素有很多,比如岩心渗透率、润湿性、界面张力、油相粘度等。许多学者对上述影响因素做了充分研究,但没有给出各因素影响渗吸采收率的重要程度。利用正交试验法,以渗透率、润湿性、界面张力、油相粘度四个因素,每个因素取三水平,按L9(34)正交试验方案,设计了9组实验,实验结果表明,各因素影响渗吸采收率的重要性为润湿性>渗透率>油相粘度>界面张力。该实验结果对利用渗吸法经济有效的采油具有一定的参考价值。There are many factors affecting spontaneous imbibition recovery, such as core permeability, wettability, interfacial tension, oil viscosity and so on. Many scholars did full study on the factors, but they did not determine important degree of the various factors affecting spontaneous imbibition recovery. In this paper, L9（3^4） orthogonal experiment was designed with four factors and three values including core permeability,wettability, interfacial tension and oil viscosity. There were nine groups of experiments. The result shows the importance of various factors affecting spontaneous imbibition is as follows： wettability〉 core permeability〉 oil viscosity〉 interfacial tension. The results of this experiment have some reference value for cost-effective oil recovery by using imbibition method.
