Change of ground stress influences pore pressure and oil potential, thus has a great influence upon oil migration accumulation.
地应力变化影响孔隙压力和油势，因而对石油运移和聚集有重要影响。
The paper discusses the migration condition of POre particle under hydrodynamism emphatically, and analyzes the influences of different types driving fluid to migration according to experiments.
本文着重讨论了水动力作用下孔隙微粒运移条件，结合室内实验分析了不同类型的驱动流体对运移产生的影响。
The effects of anions in pore solution and water saturation degree on the testing results of PERMIT ion Migration test are studied.
研究了混凝土孔溶液中阴离子和饱水程度对于PERMIT测量结果的影响。
Thus, studying sandstone diagenesis is an important link for analysis of ion migration in the evolution of pore-water.
因此，深入研究砂岩成岩作用是分析孔隙水演化过程中离子迁移的重要环节。
The squeezed out water is kept moving for the same time and even longer, and the path of its migration may cover hundreds of kilometers, always within the narrow pore space and at a very low speed.
被压力挤压出的水将会同时流动或流动时期会更长，水运移的路程可以达几百公里，运移的通道则限于窄窄的孔隙空间。而且运移的速度也非常之慢。
Because pore medium is filled with water at first, the process of oil and gas migration is that the oil and gas is continually refilled and water escaped under differential pressure.
由于孔隙介质中最初是充满水的，因此孔隙介质中油气进入过程是油气在压差作用下不断注入而水不断泄出的过程。
Because pore medium is filled with water at first, the process of oil and gas migration is that the oil and gas is continually refilled and water escaped under differential pressure.
