Abstract

The technology for nonexplosive seismic exploration of oil and gas reservoirs uses pulsed electromagnetic sources of seismic signals. Aiming to improve the technology efficiency, it is suggested to upgrade control in order to properly adjust the equipment operation mode. As a control parameter, the absolute displacement of the seismic source is chosen. This parameter is determined by estimating displacement of armature relative induction coil in electromagnetic motor. In the pulsed seismic source, it is difficult to apply displacement sensors with power drive as well as remote control sensors for the determination of movement of elements in the electromagnetic motor. The analysis of electromechanical transformation of energy in the electromagnetic motor of a seismic source shows indirect determination capability of the required parameter by means of measurement of electric values in the power system: armature current and magnetic flux though the gap.
