Abstract
Summary
In this paper, we study the magnetic field sensitivity from the sources of various configurations and check the adequacy of replacing the circular loop with a square vertical frame. The performed computational experiments showed that for the approximation of a current loop, the plane of which is perpendicular to the boundaries of layers with different resistivities, the choice of a vertical frame of four sides is sufficient in terms of the accuracy of the obtained components of the magnetic field in the receiver. The result is retained when the electromagnetic field frequency and the resistivity of the medium vary for situations typical for induction logging problems in horizontal wells.
