Description
- This application claims priority to utility application Ser. No. 13/897,405 entitled “System and Method for Erecting a Drilling Rig filed May 18, 2013, which is utility application claiming priority to provisional application 61/648,624 entitled “System and Method for Erecting a Drilling Rig” filed May 18, 2012.
- This disclosure relates to an improved system and method for moving a drilling rig.
- Drilling wells for oil and mineral explorations requires an extensive amount of machinery, complicated assembly and disassembly of equipment, as well as coordination and planning for maintenance of rigs in day-to-day practice.
- At times, it is necessary to move a rig from one location to another. Land rigs have been designed to be divided into sections to move to a new place or location. However, these processes are expensive and time consuming, often taking weeks to finish.
- With the current trend of innovation in this industry, there have been improvements in the drilling process, such as cost-effective technology, upgraded machine performance, and rig mobility. However, moving drilling rigs still requires outside machinery being installed onto rig or at rig site for any movement of the rig to occur. At present, no rig possesses a built-in walking system or other movement device.
- As such, it would be useful to have an improved system and method for moving a drilling rig.
- An improved system and method for moving a drilling rig is described herein. In one embodiment, the system can comprise a lift cylinder maneuverable in a longitudinal direction, a casing having a portion of lift cylinder attached at the center of the casing, and an anchor where a top portion of the anchor is connected to the bottom portion of the lift cylinder. The casing can be mateable at the bottom portion of a drilling rig. The walking system can further comprise a pair of traverse cylinders mounted on opposite sides of the anchor and a skid pad, on which a portion of the traverse cylinder is connected. The traverse cylinder can be maneuverable in a lateral direction. The skid pad can be connected to the bottom portion of the mounting plate. Furthermore, the skid pad can be capable of supporting the weight of the drilling rig.
- In addition, an improved method for moving a drilling rig can comprise expanding a lift cylinder and horizontally expanding a traverse cylinder. As a result, drilling rig can be directed laterally. The lift cylinder can be capable of lifting a drilling rig upwards such that a skid pad presses against the ground.
