Abstract

The results of measuring component magnetic field performed at a gas field near the town of Aniva, Sakhalin region, are presented. Based on the data obtained, it is shown that the anomalous local change in the geomagnetic field in the area of the gas field is caused by a change in the metal structures of this field due to the influence of the tides of the Aniva Bay of the Sea of Okhotsk. This local change in the geomagnetic field is confirmed by the correlation dependence and the temporal coincidence of the peaks of the diurnal tides with the maxima of the amplitudes of the magnetic field, as well as the semi-daily inflection of these dependencies. In addition, the article shows that the metal structures of the gas field have some local influence on the variations of the geomagnetic field in the area of this field. At a short distance from the wells, partial shielding of geomagnetic variations is observed, created by the extended ferromagnetic structures of the gas field and at long distances, there is a multiple increase in geomagnetic variations caused by the high magnetic permeability of the pipes of this deposit.
