Modular coiled tubing and sectional pipe drilling rig
First Claim
1. A drilling rig for forming and servicing a borehole comprising:
- a first transportable module forming a substructure component including a framework base structure having a ground engaging lower portion for supporting said rig,said framework base including a well head area with a vertical axis therein adjacent one end of said framework base for alignment with said borehole, and a bed area extending to an opposite end of said framework base;
a second separably transportable module forming a mast component of said drilling rig,said mast component including a base portion anda mast framework having a longitudinal central axis and being pivotally attached to said base portion for movement between a lowered position and a raised operative position,said base portion of said mast component being shaped for reception in said bed of said substructure component of said first module and positioning said second module component for alignment of said mast framework in the raised position with said axis of said well area of said first substructure component, andsaid base portion of said mast component defining an upper support area; and
a third separably transportable module forming an injector component,said injector component comprising;
a tubing injector having attachment means for connection to said mast framework, and,an injector carrier for positioning on said upper supporting area of said base portion of said mast component and supporting said injector in a location for connection of said tubing injector to said mast framework when said mast framework is in a lowered loading position to thereby allow the loading of said tubing injector into a working relation in said mast.

Abstract
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.
