fine migration

基本解释

The latent factors effecting the operation are fine particle migration and acid sensitivity.
對施工潛在的影響主要是微粒遷移和酸敏。
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.
研究結果表明，注水速度和沖刷時間的增加會導致膠結疏松的儲層內部微粒運移，使儲層滲透率陞高；
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.
疏松砂巖油藏開採過程中，油層壓力下降和採油速度的增加以及巖石結搆的破壞，是造成油層巖石微細粒運移和油井出砂的主要原因。
