摘要
新型桥塞采用卡套管接箍缝的锚定形式 ,机械方式丢手 ,皮碗方式扶正。具有零部件简单 ,加工方便 ,加工费用低 ,现场施工简单 ,施工费用低 ,密封时间长 ,防砂卡等优点 ,经现场应用 ,封堵底水明显 ,产量升高。但下放前要通井 ,不易过快 ,下放到预定位置时必须有一套管接箍缝 。
New type of bridge plug has many advantages,such as simple element,easy process,low processing charges,simple field construction,long sealing time and antisand plug etc..Through field application of new type of bridge plug,result shows that the effect of plugging bottom water is obvious,oil production is rised.But the bridge plug is also some disadvantages,it must be drifting before running tool and can’t be too quick.When the bridge plug comes to desired position,there must be a casing coupling seam.
