Adjacent well detection device, method and system

The invention discloses an adjacent well detection device, method and system, and the device is disposed on a drill collar of a first well, and comprises a transmitting probe array which comprises a plurality of transmitting probes disposed on the surface of the drill collar, and the surface of each transmitting probe is wound with a transverse coil whose normal direction is perpendicular to the axial direction of the drill collar, the multiple transmitting probes are arranged in the direction parallel to the axial direction of the drill collar. When the drill collar rotates, bipolar transient pulse signals are applied to the transverse coil, and a primary magnetic field is generated around the first well based on the combined action of rotation of the transmitting probe array and pulse excitation; the change of the primary magnetic field can generate a secondary magnetic field on a sleeve of an adjacent second well; the receiving probe is particularly a longitudinal coil wound on the drill collar, the normal
