Abstract
The present invention discloses a petroleum instrument salvaging connector, which is set on a salvage end of a petroleum instrument, for being in hooking fit with a salvaging head of a petroleum instrument salvaging device. The petroleum instrument salvaging connector comprises a salvaging connector body (); the salvaging connector body () has a stair-shaped salvaging hole; the stair-shaped salvaging hole is a blind hole and comprises a large-caliber section () and a small-caliber section (); the large-caliber section () is located at the bottom of the stair-shaped salvaging hole, and a hooking face () facing the bottom of the large-caliber section () is formed at the jointing part between the large-caliber section () and the small-caliber section (); and a sand outlet () is set at the bottom of the sidewall of the large-caliber section (). The invention further discloses a petroleum instrument. By employing the above solutions, the problem in the current drilling process may be solved that the salvaging head cannot be in hooking fit with the petroleum instrument salvaging connector due to the deposition of solid particles in the slurry in the stair-shaped salvaging hole of the petroleum instrument salvaging connector.
