Results show that initial water saturation swi has a strong effect on rateofimbibition of sandstone system.
结果表明，束缚水饱和度对砂岩体系自吸速度有较强的影响。

Many factors affect the process of spontaneous imbibition. This paper is focused on the effect of initial water saturation and rock lithology on rateofimbibition and oil recovery.
影响自吸的因素有很多，文中主要研究束缚水饱和度和岩石性质对自吸速度及采收率的影响。

The method is provided based on the principle that the wettability of rock surfaces is a key factor affecting the spontaneous imbibitionrate as the rock contacts fluids.
