摘      要:The flow performances of water, white oil and Hydrolyzing Polyacrylamide (HPAM) solution in fused quartz channels and the effect of wettability on the microscale flows have been studied respectively in this paper. The adaptability of classical fluid mechanics in channels with different sizes has been discussed. The results show that water flows in channels of 2μm diameter also have few size effects and white oil flow accord with classical fluid mechanics theory in channels of 25μm diameter too, but polymer solution appears an obvious size effect as diameters of channels decrease to 16μm. The wettability does not produce any influences on the water or white oil flows in channels of 25μm or 50μm diameter. The experimental technology of microscale flows has been first applied for studying the flow performances of pores in low permeability reservoir. This study found a base for deep investigating the percolation mechanism in low permeability reservoirs.
