通过动力三轴试验，给出了饱和砂的残余孔隙水压力的全量表达式和不同液化破坏阶段的临界孔隙水压力比的表达式。
Expressions of total residual pore pressure and critical ratio of pore pressure in different failure stages of liquefaction in saturated sand are deduced based on the dynamic tri-axial tests.
在后续注水过程中，存在于大孔道的弱凝胶迫使后续注入水改向进入未被注入水波及的小孔隙，驱替的残余油滴聚集并形成油墙。
In the post-water flooding process, WG in the larger channels diverts the injected water entering the smaller pores and displacing residual oil to form oil bank in the front of the displacing water.
孔隙类型主要有残余粒间孔、粒间溶孔、粒内溶孔、杂基孔和微裂缝。
The pore types include residual intergranular pore, intergranular dissolved pore, intragranular dissolve pore, matrix pore and microfracture.
