摘　　要：随着油田进入高含水期而采用大排量提液后,套损井逐年增多。这是因为加大采液强度后,在较大生产压差条件下开采,井底油层产生较大激动,结构易被破坏而引起油层严重出砂。Large displacement extract with the high water cut stage oiIfield casing damage well, increasing year by year. This is because the increase of the strength of the fluid production, mining in larger production pressure conditions, bottomhole reservoir the gzeater excitement structure susceptible to damage caused by the reservoir serious sand.
