Rotary rigid centralizer with runner guide structure

The invention relates to the technical field of rigid centralizers, in particular to a rotary rigid centralizer with a runner guide structure, which comprises a sleeve, a rotatable centralizer component is sleeved on the sleeve, and positioning components are movably arranged at the top and the bottom of the centralizer component. The positioning assembly is used for quickly locking and fixing the centralizer assembly on the outer wall of the casing pipe; according to the rotary rigid centralizer with the flow channel guiding structure, the positioning assembly is arranged, the centralizer assembly can be rapidly locked and fixed to a casing pipe through the positioning assembly, compared with traditional bolt fixing, the centralizer assembly can be rapidly fixed or disassembled, and the centralizer assembly can be rapidly fixed or disassembled according to the specific situation in a well. And the position of the centralizer assembly is quickly and conveniently adjusted, so that the use convenience of the ce
