2012
The utility model relates to a horizontal well completion tool, in particular to a rotating homing type guiding shoe, which comprises a rotating head, wherein a female thread is arranged on the inner wall of the upper end of the rotating head, the outer wall of the lower end of the rotating head is designed into a spherical surface, the lower end of the rotating head is connected with a rotating sleeve, the lower end of the rotating sleeve is connected with a guiding body, and the rotating head and the rotating sleeve are sealed through a carbon fiber ring. The rotating homing type guiding shoe achieves automatic rotation, can automatically adjust direction when a completion string is installed to meet resistance, and guides the completion string to safely and smoothly go to a design position. The rotating homing type guiding shoe overcomes the defect that an existing completion string can not be installed smoothly when meeting resistance.
