| 摘 要： | 油田分层开采要求封层工具既要性能可靠、操作简便，又能根据需要随时取出(或钻掉)。可捞可钻式桥塞主要配件由可钻材料加工而成，利用引燃送进工具的火药产生的高压气体做座封动力，采用自然伽玛或磁感应定位，使其在封闭高含水层、简化生产管柱方面显示出了突出的优越性。文章介绍了QSA型可捞可钻式桥塞的结构特点和使用情况。 |

| Abstract: | Oilfield zonal production needs tools in layer sealing which have reliable performance, handy operation and can be taken out at all times according to the demand. Fishable and drillable bridging plug is composed of seating and sealing outfit, anchoring outfit and sealing outfit. Main assemblies are machined by drillable material. Using high pressure gas produced by igniting powder is used to feed tools as dynamic setting and it is located by natural gamma or magnetic induction,which makes fishable and drillable bridging plug display outstanding superiority in aspects of sealing high water-cut layer and simplifying producing pipe string. It has features of reasonable structure, good pressure resistance and temperature resistance performance, locating layer precisely , handy operating, low expense and being fishable and drillable. Application in 38 wells in our own field has showh that, success rate is 100% in sealing layer.Fishing in two wells, bailed smoothly which has 100% success rate. |
