SiamMaster - GDIS 2-7 GT


  • an electric-driven electronic control «SIAM-LESP-6» slickline winch is used, also there is free fall. Power supply is from one-phase industrial network 220 V, 50 hz;
  • the possibility of self-contained lab exploitation (without connection to external power supply rack at a well site) is realized by means of two independent sources: a self-contained diesel generator and a voltage source invertor (invertor) 24V-220V (emergency);
  • AC frequency changer provides infinitely variable speed control of lowering slickline from 7% to nominal;
  • change in direction of slickline movements is made by changing rotating direction of a motor shaft - electronic reverse;
  • running depth gauge MI-1 doesn’t have a measuring wheel (excluding redundant slickline strain);
  • speed, running depth and pulling force is controlled by an electronic meter. The running depth control is duplicated by a mechanical meter.
  • there are 2 working areas: a cabin and an engineering compartment with watch windows, an upper and an evacuation (emergency) hatches in the snow and swamp-going vehicle. Operating of a pulling-and-running mechanism is carried out in 2 modes: slickline is run through an open rear door, and if necessary, through a service slotted opening with stabilizing pulleys set
  • to light the wellhead, 220 V line-operated spotlamps and a pilot-lite with 24 V on-board power system are installed;
  • to light engineering compartment equipment, 220V line-operated lamps and dome lights with 24 V on-board power system are installed;
  • there is an amplified telephone;
  • there is a watch windows heater
  • driver's cabin and engineering compartment are equipped with self-contained heaters 24 V (diesel fuel) in addition to in-house heaters of snow and swamp-going vehicle;
  • to improve working conditions, the following equipment is installed: a chest bench, a table, sleeping berths, a chest, and so on (optional);
  • it is equipped with a hoisting device to change a drum (optional);
  • Simplified kinematic scheme
  • small mass;
  • manual spooler drive;
  • pulling force stabilization mechanism;
  • upgradability;
  • low cost;
