The invention relates to an inductive probe for inducing an array structure of coils. The inductive probe consists of a metal core rod, a composite copper pipe, coil frameworks and space adjustment members, wherein the metal core rod is in a hollow structure; opposite rod body walls, vertical to the axis of the metal core rod, of the metal core rod are provided with thread holes penetrating from interior to exterior; the outer round wall of a metal core rod body is provided with coil framework thread passing grooves and oil flowing grooves; the composite copper pipe is sleeved outside the metal core rod, and the outer round wall of the composite copper pipe is provided with coil framework sliding grooves; the coil frameworks are provided with thread holes and coiling grooves, the coils are wound on the coiling grooves, the coil frameworks are arranged in an array mode and installed on the coil framework sliding grooves of the composite copper pipe, each coil framework consists of a transmitting coil and eight groups of receiving coils, and each group of receiving coils is composed of a main receiving coil and an auxiliary receiving coil; and the space adjustment members are installed between the adjacent coil frameworks. According to the invention, array and digital measurement can be realized, and detection curves with multiple longitudinal resolutions and multiple radial detection depths can be obtained.
