Abstract
In one embodiment, a support structure for use on a rig floor and for supporting a unit used to manipulate tubular components through a wellhead comprises a support plate adapted to securely mount the support structure to said unit, a passage in the support plate of sufficient diameter to allow tubular components to pass therethrough, a plurality of rig engaging members and at least one tensile member mount. The unit used to manipulate tubular components through a wellhead may be a compact snubbing unit or may be a push/pull unit. The support structure may further comprise a worker platform to support a worker above the rig floor. Various push/pull system embodiments, for use on a rig to manipulate tubular components through a wellhead, are also taught.

A support structure for use on a rig floor and for supporting a unit used to manipulate tubular components co-axially in and out through a wellhead, comprising:
- a support plate adapted to securely mount the support structure to said unit used to manipulate tubular components co-axially in and out through a wellhead and adapted to distribute downward forces to the rig floor;
- a passage in the support plate of sufficient diameter to allow tubular components to pass therethrough;
- a plurality of rig engaging members;
- and
- at least one tensile member mount to facilitate the connection of one or more tensile members between the support structure and the rig floor while tubular components are manipulated co-axially in and out through the passage.
A support structure for use on a rig floor and for supporting a unit used to manipulate tubular components through a wellhead, said unit having a plurality of jacking rams, the support structure comprising:
- a support plate adapted to securely mount the support structure within said unit used to manipulate tubular components through a wellhead and further adapted to distribute downward forces to the rig floor;
- a passage in the support plate of sufficient diameter to allow tubular components to pass therethrough;
- a plurality of rig engaging members connected to the support plate;
- a plurality of tensile member mounts to facilitate the connection of one or more tensile members between the support structure and the rig floor while tubular components are manipulated co-axially in and out through the passage;
- and
- a plurality of ram passages in the support plate adapted to securably mount the plurality jacking rams;
- wherein, during operations, any downward forces are generally distributed into the rig floor through the support structure and the plurality of rig engaging members.
A push/pull unit for use on a rig floor and for manipulating tubular components through a wellhead, said push/pull unit comprising:
- a support plate;
- a passage in the support plate of sufficient diameter to allow tubular components to pass therethrough;
- a plurality of rig engaging members projecting from the support plate;
- at least one tensile member mount;
- a traveling slip assembly;
- a stationary slip assembly mounted to the support plate;
- at least one jacking ram securably mounted between the support plate and the traveling slip assembly;
- wherein said traveling slip assembly, said stationary slip assembly and said at least one jacking ram are actuatable to manipulate tubular components through a wellhead.
