Overview

The Conrad Combi 500 is a powerful and robust drilling rig that can also be easily used on an international level. A stable set-up during the roughest drilling conditions is safeguarded due to its solid mast construction.

The Conrad Combi 500 has already been deployed practically in many models. The Combi 500 has proven its quality on the domestic and international market to the full satisfaction of end users and has developed to become a modern and reliable rig. Equipped with an automatic drill pipe manipulation system and because all important drilling functions can be radio controlled, the Combi 500 is very advanced and one of the most modern of drilling rigs in its class. The Combi 500 can be fitted out based on customer specifications for straight flush drilling, reverse circulation/airlift drilling, percussion drilling, sonic drilling, coring and Down-The-Hole drilling.

Drilling methods

The Combi 500 can be fitted out based on customer specifications for one of the drilling methods described below.

  • Tool
    Reverse circulation drilling

    Reverse circulation drilling up to approx. 70 to 80 metres can be carried out with a reverse circulation pump and reverse circulation drilling bit diameters up to approx. 1000 mm. *

  • Tool
    Airlift

    The airlift drilling principle by using a compressor is the appropriate method to continue the reverse circulation drilling with a hole diameter of approx. 1000 mm to a depth of 400 metres. *

  • Tool
    Straight flush drilling

    Holes with a diameter of approx. 350 mm can be continued up to a depth of 500 metres by using a water, mud or foam circulation system with this drilling method. *

  • Tool
    Percussion drilling

    By equipping the Combi 500 with a rotary table and a stroke mechanism, percussion drilling is possible up to a depth of at least 150 metres with a max. casing diameter of 420 mm.

  • Tool
    Auger drilling

    The Combi 500 can drill with both hollow stem and full augers that have an outer leaf diameter of approximately 500 mm with the standard 6" drill head.

  • Tool
    Counter flush drilling

    For special activities the Combi 500 can be equipped with a counter flush system for sampling for exploration objectives to name but one example.

* Will depend on the geological and the soil conditions.

Operator convenience & comfort

Conrad Stanen has translated a lot of experiences of drilling rig operators into the operating friendliness of its designs. This ensures that productivity is increased as a whole and that it is made more pleasant for the drilling rig operator to work with the rig. A few examples of this are:


  • Full drill pipe manipulation system that ensures that drill pipes no longer have to be inserted and extracted manually (no physical load)
  • A semi or fully automatic facility for the above to ensure that manual control is limited to a minimum (operating comfort)
  • Radio remote control for all important drilling functions and setting up the drilling rig (good visibility of the drilling process and surrounding area)
  • Automatic greasing system
  • A high engine performance that increases productivity

The drilling rig operator can set himself or herself up in the area of the rig with his or her radio control unit. Inserting and extracting drill pipes are automatic tasks and do not lead to physical loads. This also prevents the risk of body parts becoming trapped.
