Horizontal well operation sand-washing centralizing and guiding device

A horizontal well operation sand-washing centralizing and guiding device comprises a guiding head (1), a rapid plug-in collision head (2), a sleeve (3), a centralizer (4), a wash pipe (5) and an upper connector (6). The horizontal well operation sand-washing centralizing and guiding device is characterized by being of a double-cylinder sleeve-insertion structure; the guiding head (1) is arranged at the left end of the wash pipe (5), the upper connector (6) is arranged at the right end of the wash pipe (5), and the rapid plug-in collision head (2) is arranged at the left end of the sleeve (3); the centralizer (4) is arranged on a body of the sleeve (3), the wash pipe (5) is inserted into the sleeve (3), and the guiding head (1) is connected with the rapid plug-in collision head (2) in an inserted mode. The horizontal well operation sand-washing centralizing and guiding device is novel in design, simple in structure and convenient to operate, improves sand washing effect of horizontal well operation, prolongs t
