PROSPECTS OF THE APPLICATION OF MODERN SOFT-MAGNETIC MATERIALS IN MAGNETOMETRIC GEOPHYSICAL EQUIPMENT

Abstract

In the last decade, the development of borehole magnetometry has been determined by the increasing demand for magnetometric equipment and by the broadening scope of its application. At present, two types of three-component digital ferroprobe borehole magnetometer-inclinometers have been developed at the Institute of Geophysics, Ural Division of the Russian Academy of Sciences. The first type is based on the second harmonic, while the second one is of the time-pulse type. This equipment has been widely used for the prospecting and exploration of iron, nonferrous and precious metals, and diamond and hydrocarbon deposits, as well as being utilized for the solution of technological problems in oil-and-gas fields.
