Positioning and cutting device for glue wing of drilling inclinometer centralizer

The invention relates to the technical field of drilling tools, in particular to a positioning and cutting device for a glue wing of a drilling inclinometer centralizer. The positioning and cutting device comprises a cylindrical body, a cover body and a columnar lining body; the cover body is integrally fixed to the upper end of the cylindrical body, and the columnar lining body is integrally fixed to the middle portion of the cover body; the columnar lining body is located in the cylindrical body, and a gap exists between the columnar lining body and the cylindrical body; and at least two vertical anti-sliding long cutting openings are formed in the body along the circumference at intervals. The positioning and cutting device is reasonable and compact in structure and convenient to use, and through cooperative use of the cylindrical body, the cover body and the columnar lining body, size-limited cutting on the glue wing on the drilling inclinometer centralizer can be achieved, and the glue wing on the drilling inclinometer centralizer is accurately attached to the drift diameter inner wall of a non-magnetic drill collar water hole to move downwards, so that the limiting anti-vibration effect of a drilling inclinometer is achieved. The positioning and cutting device has the beneficial effects of being safe and reliable. Operation is convenient, the working efficiency is improved, and the service life is prolonged.
