Abstract

The invention relates to a drilling rig (10) for deep well drilling for the onshore sector, comprising at least one drilling device (30), wherein the drilling rig (10) is designed to be movable with respect to the land surface. The object of the invention is to provide a drilling rig (10) with which a multiplicity of wells can be drilled at short distances apart with short set-up times. This object is achieved in that the auxiliary units (50 to 59) required for the drilling are arranged substantially inside the drilling rig (10), and in that the position of the drilling device (30) inside the drilling rig (10) is movable with respect to the drilling rig (10).

Claims

1. A drilling rig for deep well drilling for the onshore sector, comprising at least one drilling device, wherein the drilling rig is movable with respect to the land surface, wherein auxiliary units required for the drilling are arranged substantially inside the drilling rig, and the position of the drilling device inside the drilling rig (10) is movable with respect to the drilling rig.

2. The drilling rig as claimed in claim 1, wherein at least two drilling devices are provided.

3. The drilling rig as claimed in claim 1, wherein at least two levels are provided in the drilling rig, on which levels at least on of the auxiliary units, the drilling device, safety equipment, auxiliary drilling devices and the control system of the drilling rig are situated.

4. The drilling rig as claimed in claims 1, wherein all the auxiliary units required for the drilling are arranged inside the drilling rig.

5. The drilling rig as claimed in claim 1, wherein the drilling rig is surrounded by a casing which completely screens the drilling rig from environmental influences.

6. The drilling rig as claimed in claim 5, wherein the casing is provided with closable openings.

7. The drilling rig as claimed in claim 1, wherein the auxiliary units are interchangeably arranged in a modular manner.

8. The drilling rig as claimed in claim 7, wherein the modularity is achieved by an arranging the respective auxiliary units in containers.

9. The drilling rig as claimed in claim 1, wherein the drilling rig includes a travel mechanism.

10. The drilling rig as claimed in claim 6, wherein the auxiliary unit modules can be at least one of inserted and exchanged through the openings in the casing.

11. The drilling rig as claimed in claim 1, wherein a crane module is arranged above the drilling device.

12. The drilling rig as claimed in claim 1, wherein the drilling device and/or auxiliary drilling devices are arranged on at least one movable base.

13. The drilling rig as claimed in claim 1, wherein a preventer for at least one of the drilling device and the hydraulic supply of the borehole (choke, manifold) is arranged on at least one movable base.

14. The drilling rig as claimed in claim 12 wherein the base elements can be moved synchronously.

15. The drilling rig as claimed in claim 1, including a helicopter landing deck on the top of the drilling rig.

16. The travel mechanism of claim 9 wherein the travel mechanism has cross-country mobility

17. The travel mechanism of claim 9 wherein the travel mechanism consists of individual crawler travel mechanisms.

18. The movable base of claim 12 wherein the movable base is a carriage, which is movable relative to the drilling rig.

19. The movable base of claim 13 wherein the movable base is a carriage, which is movable relative to the drilling rig.
