The coil used in the induction logging tool includes the skeleton and the windings wound on the skeleton. There is only one set of windings on each skeleton. At the same time, when the assembly is completed, it is composed of many different parts, and the installation process is cumbersome. At the same time, since there are different degrees of error between each part, the accumulated error is relatively large, and the thermal stability of the formed coil is reduced, which affects the authenticity and reliability of the logging data.
