具有增强的恢复力和自动密封性能的井眼管道扶正器
摘要：
一种扶正器，包括构造为固定至管道的外表面的第一限动环。第二限动环与所述第一限动环间隔开并构造为固定至所述管道的外表面。包括多个周向间隔开的纵向隔离装置，每个纵向隔离装置在每个纵向端联接至所述限动环中的一个。多个周向间隔开的第一弓形弹簧中的每一个在它的一个纵向端联接至所述第一限动环并且在它的相对的纵向端联接至设置在所述第一限动环和第二限动环之间的第一浮箍。多个周向间隔开的第二弓形弹簧中的每一个在它的一个纵向端联接至所述第二限动环并且在它的相对的纵向端联接至设置在所述第一限动环和第二限动环之间的第二浮箍。
摘要（英）：

A centralizer includes a first stop collar configured to be affixed to an exterior surface of a pipe. A second stop collar is spaced apart from the first stop collar and is configured to be affixed to the exterior surface of the pipe. A plurality of circumferentially spaced apart longitudinal spacers is included and each is coupled at each longitudinal end to one of the stop collars. A first plurality of circumferentially spaced apart bow springs is each coupled at one longitudinal end thereof to the first stop collar and at an opposite longitudinal end thereof to a first floating collar disposed between the first and second stop collars. A second plurality of circumferentially spaced apart bow springs is each coupled at one longitudinal end thereof to the second stop collar and at an opposite longitudinal end thereof to a second floating collar disposed between the first and second stop collars.
