Abstract

The invention discloses a large-diameter drill bit centralizing device. The large-diameter drill bit centralizing device comprises a drill pipe, wherein a sleeving mechanism is fixedly installed on the side surface of the drill pipe, the sleeving mechanism comprises a guide ring, a first reinforcing plate, a second reinforcing plate, a first support plate and a second support plate, the first reinforcing plate and the first support plate are fixedly connected to the upper end of the guide ring, the first reinforcing plate is located between the guide ring and the first support plate, the second reinforcing plate and the second support plate are fixedly connected to the lower end of the guide ring, and the second reinforcing plate is located between the guide ring and the second support plate. According to the large-diameter drill bit centralizing device, the technical problem that a broken drill bit cannot be accurately and efficiently salvaged from a well in the prior art is solved.

Description

technical field [0001] The invention relates to the field of well drilling, in particular to a large-diameter drill bit stabilizing device. Background technique [0002] The drill bit is the main component of the drilling equipment, its main function is to break the rock and form the borehole; when drilling a large-diameter hole, due to the downhole working conditions or environmental reasons, the drill pipe breaks off or breaks, causing the drill tool to fail in the larger hole. Centered, affects the progress of drilling. [0003] In the process of righting the existing drill bit, manpower is needed to judge whether the drill bit is socketed and fixed and whether the drill pipe is in a vertical state by experience, and then the broken drill bit is salvaged through the drill pipe, resulting in poor fishing efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a large-diameter drill bit straightening device, the main purpose of w...
