FIELD: engineering of equipment for geophysical research.
SUBSTANCE: method includes connecting or disconnecting power source to electronic circuit immediately before lowering or after raising of device, by effect of alternating electromagnetic field from outer source of electromagnetic energy on electronic key circuit through device body. For this purpose by means of outer electromagnetic energy source alternating magnetic flow is initiated, which is converted by electromagnetic energy converter inside the well device to feeding and control voltage for electronic key, by means of which autonomous power source is connected or disconnected dependent on selection of appropriate converter. Device is provided with outer source of electromagnetic energy. Converters of electromagnetic energy are inserted inside the body, which are maximally proximate to inner surface of body, but are not in contact with it, and are maximally distanced from each other. Output of one converter of electromagnetic energy is connected to input for disabling an electronic key. Input of electronic key is connected to power source. Output of electronic key is connected to electronic circuit of device.
EFFECT: higher autonomy of device.
