description The utility model provides an inductance type three-arm hole diameter logging instrument. The inductance type three-arm hole diameter logging instrument comprises a barrel-shaped shell, three hole diameter walls, three inductance type transducers and a measuring module. Each inductance type transducer is composed of a hollow metal shaft bar, three coils wound around the hollow metal shaft bar in different directions, and a transducer mandrel arranged in the hollow metal shaft bar. The three hole diameter sections are arranged in the axial direction of the barrel-shaped shell and circumferentially and evenly distributed on the barrel-shaped shell. One end of each hole diameter wall is connected with the barrel-shaped shell, and the other wall of each hole diameter section is connected with the transducer mandrel of the corresponding inductance type transducer. The coils of the three inductance type transducers are connected with the measuring module. The inductance type three-arm hole diameter logging instrument is long in service life and high in resolution.
