可控重复坐封智能桥塞的设计

Design of Intelligent Controllable & Repeated Bridge Plug Available for Sealing

桥塞是一种重要的石油完井工具,主要用于油气井的封层.设计了一种可控重复坐封智能桥塞,对其结构进行了介绍,对坐解封、锁紧、锚定和定位方式进行了分析.这一可控重复坐封智能桥塞整体结构简单可靠,操作方便,解决了当前桥塞压裂效率低和不能重复坐封的问题,能够在井下恶劣环境中实现重复坐封.

The bridge plug is an important oil completion tool used primarily for the sealing of oil and gas wells.An intelligent controllable&repeated bridge plug available for sealing was designed,and its structure was introduced.The methods of sealing,unsealing,locking,anchoring and positioning were analyzed.The overall structure of the intelligent controllable&repeated bridge plug available for sealing is simple and reliable and convenient for operation,and solves the problem that the current bridge plug has low fracturing efficiency and can not be set for repeated sealing,and can realize repeated sealing in a harsh underground environment.
