The proposed equipment is intended for by-point measurements, with a given measurement pitch, of three vector components of acceleration, which act on a downhole device under the effect of dynamic processes occurring in a borehole, such as, for instance, flowing of water, oil, gas, etc.
DISTINCTIVE FEATURES AND SPECIFICATIONS
• The device is designed for operation using a single-core armored cable of 6 km in length.
• The device contains a point thermometer.
• Data are recorded with an IBM-compatible computer via the COM port.
