0-3000M Geophysical Borehole Logging Equipment

Geophysical borehole logging equipment is used in exploration for water well, coal mine and other mining borehole. The system identifies lithologies and stratigraphic correlations in boreholes, cased or uncased, liquid or air filled. The logging depth is 0-3000 meters.

Principle of Instrument Operation:

The instrument is powered by adaptive mode. According to the resistivity of the rock layer automatically select the appropriate supply voltage. At the same time, the voltage between the power supply current and MN is measured, which is processed into digital signals through amplification, detection, and analog-to-digital conversion, and sent to PC via USB communication port for recording and drawing. Automatically turn on or off the AB power supply current according to the received power supply command (issued by PC).If the spontaneous potential is measured, the power supply is turned off to reduce the influence of the artificial electric field on the self-electric measurement. The instrument performs the apparent resistivity or spontaneous potential measurements along with the photoelectric pulse signals from the depth meter (wellhead pulley or depth measuring head), which are processed and converted into real-time logging depth and speed. The depth information and downhole measurement parameters are sent to the PC.
