CHUANZHONG Y415 RETRIEVABLE BRIDGE PLUG AND ITS APPLICATIONS

    Graphical Abstract
    • Abstract
  • Chuanzhong Y415 retrievable bridge plug is composed of slip grip bridge plug body, receiving basket fishing assembly and driving lever etc. Its advantage is that it can be used compositely and repeatedly. It can bear high pressure and can be used to plug lower formation instead of cement plug. Good results have been obtained in field applications of 42 wells. This paper introduces its structure,field operation technology and some field application typical models and examples.
