It generally takes place when a less viscous fluid displacesa more viscous fluid typically in porous media. Nowadays, such phenomena have extensively been studied due to itsimportance in many industrial fields. In this paper, the effects of surface wettability on finger pattern are studied and simulatednumerically by the Lattice Boltzmann method (LBM). The displacement efficiency is investigated by using two parameters,namely, the breakthrough time and the areal sweep efficiency. The simulation has demonstrated that surface wettability willinfluence the finger pattern no matter the gravity is considered or not, but in the presence of gravity, the finger pattern is muchmore complicated and irregular due to the coexistence and competition of capillary force, viscous force and gravity. 关键词：IMMISCIBLE FLUIDS porous media VISCOUS FINGERING WETTABILITY
