With the ceaseless injection of oil and the migration passage prolonging, the result is that migration force increases and oil comes into little hole near charging point.
随着油的不断注入，油相通道的延长，导致运移驱动力增加，这相应导致油进入近注入点的较小的孔隙。
When oil enters the hole of water-wet sandstone driven by pressure difference, oil migrates following a line of less resistance because of the migration force of oil is bigger than that of water.
油在压差驱动下注入亲水砂岩孔隙的过程中，油的运移阻力比水大，因而，油往往沿阻力较低的有限通道运移。
Hall coefficient depends on electronic concentration and the relative values of empty hole concentrations and their migration rate in the semiconductor.
而霍耳系数取决于半导体材料中电子浓度和空穴浓度的相对大小及其迁移率之比。
However, when the length of hole enlargement is larger than certain range, the cuttings static migration law and dynamic migration law is not so much different in hole enlargement section.
而当扩径段长度大于一定范围时，岩屑在此段的静态运移规律和动态运移规律差别不大。
When the hole diameter is equal to the particle size, the encumbrance force is the least and the velocity of boundary migration is the highest.
晶界位于粒子直径区位置时所受的阻力最小、运动速度最大。
