Novel sidewall contact wing of rotary steering drilling system
The invention discloses a novel sidewall contact wing of a rotary steering drilling system. The minimum plate thickness of the end, close to a drill, of the sidewall contact wing is 16.88 m; the sidewall contact wing comprises a main sidewall contact wing body, a positioning square cotter and a supp...

| description | The invention discloses a novel sidewall contact wing of a rotary steering drilling system. The minimum plate thickness of the end, close to a drill, of the sidewall contact wing is 16.88 m; the sidewall contact wing comprises a main sidewall contact wing body, a positioning square cotter and a support sheet; the positioning square cotter and the support sheet are fixed to the main sidewall contact wing body through non-magnetic welding; straight groove openings are formed in a rib plate at one side of the sidewall contact wing, and stress releasing grooves are formed in the outer surface of the sidewall contact wing. The novel sidewall contact wing has the advantages that since the plate thickness of the end, close to the drill, of the sidewall contact wing is reduced, hanging and clamping of the end, close to the drill, of the sidewall contact wing and the well wall during drilling are effectively avoided, and the borehole passing performance of a guide tool is improved; the thickness of an alloy coating on |
