fine migration

基本解释

The latent factors effecting the operation are fine particle migration and acid sensitivity.
对施工潜在的影响主要是微粒迁移和酸敏。
The research results show that increasing flooding rate and flushing time lead to fine particle migration in the unconsolidated reservoir and the permeability increase of the reservoir.
研究结果表明，注水速度和冲刷时间的增加会导致胶结疏松的储层内部微粒运移，使储层渗透率升高；
Reservoir pressure decline, the increase of recovery rate and the damage of rock structure are main reasons of micro fine migration and sand production during oil recovery process of such reservoirs.
疏松砂岩油藏开采过程中，油层压力下降和采油速度的增加以及岩石结构的破坏，是造成油层岩石微细粒运移和油井出砂的主要原因。
