摘要
在油田生产中 ,部分油井因固井质量差发生管外窜槽以及套管出现漏点 ,导致水层出水 ,油井含水上升。针对在二次固井时易卡管柱和固井灰浆回吐 ,影响工艺效果的难点 ,介绍可插入式桥塞的结构、工作原理和特点。通过现场应用 ,取得了较好的效果。
The containing water of some oil well rises in the production of oil field because the place that the quality of well cementation is poor occurs channelling and the cannula arises disrepair. In order to solve the problems that the pipe string gets stuck in the construction work and the mortar returns, this paper gives the introduction for the intromittent bridge plug of structure ,working principle .The field test proves that the intromittent bridge plug have better applied purpose.
