Description

LAND BASED DYNAMIC SEA MOTION SIMULATING TEST DRILLING RIG AND METHOD.

The present invention relates to the field of drilling rigs, in particular to the development of offshore drilling rigs of the type that is to be installed on a floating offshore drilling vessel and as such subjected to sea state induced motions.

An example of a drilling rig adapted for installation on a floating offshore drilling vessel is disclosed in US6763898. This known drilling rig comprises: - a drilling tower embodied as a mast having a foot to be secured to the hull of the vessel, the mast being provided with a hoisting device adapted to manipulate a drill string section in a vertical firing line, - a drilling tubulars storage adapted for vertical storage of drilling tubulars, e.g. drill pipe stands, - a tubulars racker device arranged and configured to move drilling tubulars between the drilling tubulars storage device and the firing line allowing for assembly and disassembly of a drill string section in the firing line.

When installed on the vessel the drilling rig and all its components are subjected to sea state induced motions, e.g. to roll motion. It is noted that the height of the drilling rig can be very substantial, e.g. more than 50 meters, e.g. in view of handling, including storing, multiple joint tubular stands, e.g. triples or quads or even longer stand, e.g. stands having a length exceeding 100 foot.

In W02009/048322 it is disclosed to provide the floating drilling vessel with a roll damping system to counter roll motion.

The present invention aims to facilitate and enhance the further development of drilling rigs that are to be installed on floating offshore drilling vessels.

The present invention achieves this aim by providing a land based dynamic sea motion simulating test drilling rig comprising: - a soil bound foundation, e.g. a pile foundation comprising multiple piles, - a pivot structure secured to said foundation, said pivot structure providing at least one horizontal pivot axis, - a motion base mounted on said pivot structure and pivotable about said at least one horizontal pivot axis relative to the foundation, e.g. simulating sea state induced roll motion, - a drilling tower erected on said motion base and having a foot that is secured to said motion base, the drilling tower being provided with a hoisting device adapted to manipulate a drill string section in a vertical firing line, - a drilling tubulars storage adapted for vertical storage of drilling tubulars, e.g. drill pipe stands, said tubulars storage secured to said motion base, - a tubulars racker device secured to said motion base, and arranged and configured to move drilling tubulars between the drilling tubulars storage device and the firing line allowing for assembly and disassembly of a drill string section in the firing line, - a motion drive adapted to impart cyclic pivoting motion about said at least one horizontal pivot axis to the assembly of the drilling tower, drilling tubulars storage, and tubulars racker device in order to simulate said assembly being subjected to sea state induced motion.

It is noted that each of the drilling tubulars storage and tubulars racker device may be directly secured to the motion base, but it is also envisaged, as shown in the drawings, that e.g. the racker device is connected to the tower and thereby indirectly to the motion base. Yet, even when connected indirectly, these components are subjected to the pivoting or swaying motion when the motion drive is in operation.

By provision of the land based dynamic sea motion simulating test drilling rig the development of this type of rigs to be installed on a floating offshore vessel can be enhanced as components and/or their interaction and/or accuracy of motion performed can be monitored during a test, e.g. simulating the making up and/or breaking up of a tubulars string in the firing line, whilst under simulated sea motion conditions.

When components of the rig are subjected to a prolonged test, e.g. of multiple hours or multiple days, the long-time behaviour, e.g. in view of wear, of one or more components of the drilling rig can be monitored and design changes proposed or the design accepted.

For example the tubular racker device can be tested under sea motion conditions as to the accuracy of the motion of the tubular racker device when simultaneously subjected to said simulated pivoting motion. For example one can monitor the accuracy of the motions performed by the racker device, e.g. allowing to optimize a computer program governing such motion and/or interaction with or design of one or more sensors involved in controlling motion of the racker device.

It is noted that the tower height may in embodiments be greater than 50 meters.

For example the tower and the hoisting device thereof, the tubulars storage, and the tubulars racker are adapted to handle tubular stands having a length greater than 90 feet, e.g. 120 feet drill pipe stands.

In order to allow for testing of make-up of a significant drill string section, e.g. having a length of about 100 meters, and of the lower and/or raising thereof in the firing line by means of the hoisting device of the drilling tower it is preferred to provide a deep well sunken into the soil at a location aligned with the firing line. For example a concrete lined well is provided, e.g. of stacked rings or otherwise. It is preferred for said well to have a diameter greater than said drilling tubulars, in particular such a diameter that a drilling tubular section extending into said well is able to move within the well as a result of the pivotal motion imparted to the assembly by the motion drive.

For example the diameter of the well is between 1 and 10 meters.

For example the well has a depth of at least 50 meters, e.g. of at least 75, e.g. of about 100 meters.

The well may be entirely empty so that the string is freely suspended in the well. One may also envisage, e.g. for a particular test, that the well is - e.g. in part - filled with a substrate, e.g. sand to simulate soil into which a wellbore is drilled, or e.g. with water to simulate water interaction of the suspended string.

Preferably the well is equipped with a pump device to pump out water if desired.

In an embodiment the motion drive is adapted to impart a cyclic pivoting motion having a period that lies in a range between 2 and 30 seconds. In a preferred embodiment the motion drive is a variable drive, e.g. adapted to impart any period over a range between 2 and 30 seconds.

In an embodiment the motion drive is adapted to impart a cyclic pivoting motion having a pivot angle relative to vertical of at least 1°, e.g. of at most +/-10°. For example the motion drive is adapted to impart a variable pivot angle in a range greater than +/1 °, e.g. between +/-1° and +/-5°.

For example it is envisaged that tests are performed with a cyclic pivoting of about +/- 2° and a period of between 4 and 12 seconds.

In an embodiment the pivot structure provides a single horizontal pivot axis, preferably intersecting the firing line.

In an embodiment the motion drive comprises a strut having an upper end pivotally attached to the drilling tower at an elevated position thereof and having a lower end pivotally attached to a drive motor device.

In an embodiment the rig 1 only has one such rotary storage, e.g. with a small stationary storage replacing the other rotary storage shown herein.

The drilling tubulars rotary storage rack 20, 21 is rotatable mounted so as to rotate about a vertical axis.

As is known in the art the drilling tubulars rotary storage rack 20, 21 includes slots for the storage of multiple tubulars in each drilling tubulars rotary storage rack in vertical orientation. As is known in the art the rack 20, 21 here includes a central vertical post and multiple disc members at different heights of the post, at least one disc being a fingerboard disc having tubulars storage slots, each slot having an opening at an outer circumference of the fingerboard disc allowing to introduce and remove a tubular from the storage slot. It is envisaged that in a preferred embodiment the tubulars rest with their lower end on a lowermost disc member. In the example shown it is envisaged that triple stands are stored in the rack 20, 21. The diameter of rack may be about 8 meters. A drive motor is present for drilling tubulars rotary storage rack 20, 21 that allow to rotate the drilling tubulars storage rack about its vertical axis.

The rig 1 also comprises a tubulars racker device, here two such devices 140, 140’, each arranged and configured to move drilling tubulars between the drilling tubulars storage device 20, 21 and the firing line 6 allowing for assembly and disassembly of a drill string section in the firing line.

The motion drive 50 comprises a strut 51 having an upper end pivotally attached to the drilling tower 10 at an elevated position thereof and having a lower end pivotally attached to a drive motor device 52. For example the drive motor device comprises a motor driven rocker arm 53 that is pivotally connected to the strut 51 and adapted to perform a cyclic rocking motion about a horizontal rocker arm axis 54.

The motion drive may be adapted to impart a cyclic pivoting motion having a period in a range between 2 and 30 seconds.

The motion drive may be adapted to impart a cyclic pivoting motion having a pivot angle relative to vertical of at least +/-1°.

As is preferred the single horizontal pivot axis 4 intersects the firing line 6.

The rig further comprises or is associated with a well 60 that is sunken into the soil at a position aligned with the firing line 6, e.g. a concrete lined well. The well 60 has a diameter greater than of drilling tubulars storable in the tubulars storage device, e.g. a diameter of at least one meter. A drill floor 25 may be provided, having a well center or opening therein through which a drill string passes into the well 60, along the firing line 6.

As is preferred each racking device 140, 140’ has multiple, here three motion arm assemblies. Here a lower first racker motion arm assembly 141, 141’, a second racker motion assembly 142, 142’, operable at a greater height than the first tubular racker assembly, and a third well center tool motion arm assembly 143, 143’.

Each set of motion arm assemblies is arranged on a common vertical rails 145, 145’ that is fixed to the mast 4, here each at a corner thereof.

As can be best seen in the depiction of figure 4, a drill pipe multi-joint tubular 115 is held by racker assemblies 142’ and 141’ in the firing line 6, thereby allowing to connect the tubular stand 115 to the drill string supported, e.g., by drill sting slip device 130. Each of said assemblies 142’ and 141’ carries a tubular gripper member 142’t and 141 ’t at the end of the motion arm of the assembly. Instead of both assemblies carrying a gripper member it is also possible that only one arm is provided with a gripper member that supports the weight of the gripped tubular and the other arm carries a centralizer that holds the tubular in the upright position.

The lower motion arm assembly 143 of the other racker device 140 carries an iron roughneck device 150, here with a spinner 151 thereon as well.

The motion arm 141m is here embodied a telescopic extensible arm, the arm having a first arm segment 141m - 1 which is connected to the base 141b via a vertical axis bearing 147 allowing the motion arm 141m to revolve about this vertical axis. As is preferred this vertical axis forms the only axis of revolution of the motion arm. The motion arm has two telescoping additional arm segments 141m-2 and 141m-3, with the outer arm segment being provided with a connector 148 for a tubular gripper 141’t and/or a well center tool (e.g. iron roughneck device 150).

Close to or on the drill floor the rig may have a well center tools storage structure that is adapted to store therein the one or more well center tools, e.g. an iron roughneck device 150, 150’ that are connectable to the motion arm of the lowermost motion arm assembly 143, 143’.

Each tubular racking device comprises a vertical guide rail 145 onto which corresponding guide members of the base 141b of each tubular racker assembly engage. In this example the base 141b carrier four sets of each three rollers 149 of which two rollers 149 ride along opposed faces of a flange of the rails 145 and one roller rides along a lateral side of the flange.

The racking device further comprises a vertical toothed rack 160 arranged parallel to this vertical guide rails 145. Here the toothed rack 160 is mounted on the rail 145, here on a front plate of the rail between the two flanges of the rail 145.

The base 141b of the tubular racker assembly 141 is provided with one or more, here two, pinions engaging with this vertical toothed rack. The base is provided with one or more motors 162, here two, driving the pinions, so as to allow for a controlled vertical motion of the racker assembly 141.

As is preferred the one or more motors 162 driving the one or more pinions are electric motors.

The motion arm assembly 143 holds iron roughneck device 150 above the well center for make-up or breaking up of connections between tubulars in the firing line 5. At the same time the other motion arm assembly 143’ can be equipped with a second iron roughneck device, which is then already prepared for handling different diameter tubulars.

As is preferred due to weight considerations the mast of the tower structure is a latticed tower structure and the firing line 6 is outside of and alongside a side of the tower structure. The side facing the firing line is covered with a panel.

An operator's cabin can be mounted stationary on the foundation.
