The utility model relates to a magnetic positioning logging tool, which comprises an upper connector, a shell, a lower adapter and a lower connector which are meshed and connected in turn. A threading pipe is installed coaxially in the outer shell, and a coil frame is installed around the middle part of the threading pipe. The coil is wound on the coil frame. Two magnets are arranged around the threading pipe on both sides of the coil frame, one copper sleeve is arranged on each side of the outer walls of the two magnets, and two copper sleeves are arranged on both sides of the The upper locking head support and the lower locking head support are respectively installed. The upper locking head support is clamped by shock absorber pad, locking ring and the upper joint. The lower locking head support is fixed by positioning pin and the lower turning joint. A locking head is installed on the upper and lower locking head support. Each locking head is butted with a locking cap. The cable is welded with the plug after passing through the locking head and the locking cap, and each plug is butted. One socket. The structure design of each component of the magnetic positioning diameter gauge is scientific and reasonable. It seams tightly. The installation is firm. The cable joint is fixed tightly. Two sealing rings are installed at each connection. The sealing is good, moisture-proof and waterproof.
