Downhole pressure and temperature memory gauge SAMT-3

Functions

  • Recording of pressure and temperature along the length of the borehole and / or their changes in time at any depth, for example, at the bottom during pressure build-up curve recording;
  • pressure fall-off curve and pressure build-up curve recording at the bottom;
  • measurements in the mode of multiple start / stop of the tool and its stop in overriding / decrease of pre-set values (standby mode of recording);
  • start of measurements according to pre-set values of time, pressure and temperature;

Features

  • Fully automated performance;
  • setting of operation mode and data transfer does not require dismantle, it is carried out by means of computer or pocket PC by connecting wires to electrodes on the body of the gauge;
  • automated multiple and long-term measurements are assured by large memory capacity (up to 16 million data points of pressure and temperature; each record is identified separately, up to 1000 independent records);
  • time interval programming mode of a measurement saves memory during long-term measurements and battery, reduces the time for data reading;
  • a wide range of time discontinuity from 20 ms to 1 day;
  • Gauge software allows setting operation mode of a gauge, its turn-on time, checking its battery and memory, transferring data to PC, looking through and printing recorded pressure and temperature values
