The advantages of using TDS:
- time saving in the process of pipe extension during drilling;
- reduced probability of stuck pipe drilling equipment;
- expansion (development) of the wellbore during the descent and ascent of the tool;
- improved accuracy of drilling operations for directional drilling;
- increased safety of the drilling crew;
- reducing the probability of uid release from the well through the drill string;
- relief of the descent of the casing in the zones of complications due to rotation and ushing;
- improving the quality of core.
Design features:
- hydraulic caliper brakes on disk type in each electric motor;
- traverse beam with rotating of the pipe handler by 360º;
- automatic threading off-loading system;
- oil heating system in the reduction gear and the hydraulic tank;
- IBOP, working pressure 5000 PSI or 10000 PSI;
- built in uni ed hydraulic unit;
- uni ed circulating system of hydraulic uid cooling and ltering;
- guide beam;
- control container – VFD-TDS.
The constructive design of the TDC allows it to be installed on drilling rigs of the corresponding load capacity of all domestic and foreign manufacturers.
