fine migration

基本解釋

The latent factors effecting the operation are fine particle migration and acid sensitivity.
對(duì)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(jié)果表明，注水速度和沖刷時(shí)間的增加會(huì)導(dǎo)致膠結(jié)疏松的儲(chǔ)層內(nèi)部微粒運(yùn)移，使儲(chǔ)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(kāi)採(cǎi)過(guò)程中，油層壓力下降和採(cǎi)油速度的增加以及巖石結(jié)搆的破壞，是造成油層巖石微細(xì)粒運(yùn)移和油井出砂的主要原因。
