Modular coiled tubing and sectional pipe drilling rig

摘要

A drilling rig for use in both coiled tubing injection and rigid threaded pipe operations, and consisting of a number of separably transportable modules which are assembled on site for carrying out the operations. Included in the modules are a substructure component, a mast component and an injector component. In setting up for operation, the mast component is combined on site with the substructure component which supports the assembled rig over the borehole. The mast component in location provides a loading area to support the injector component in a position for ready loading of an injector included in the injector component into the mast when required for a coiled tubing operation.
