Abstract
Description
Technical Field
[0001] The present invention relates generally to the field of drilling and, more particularly, to drilling apparatus and related drilling methods. Background Art
[0002] The following discussion of the background art is intended only to assist in understanding the present invention. The discussion is not an acknowledgement or admission that any of the material referred to is or was ever part of the common general knowledge as of the priority date of the present application.
[0003] It is well known in the art that a drilling rig is an integrated system for drilling a well, such as an oil well or a water well. A drilling rig can also be used to sample underground mineral deposits to test rock, soil and groundwater physical substances, and can also be used to install underground facilities, such as underground pipelines, instruments, tunnels or wells. A drilling rig can be a mobile device mounted on a truck, crawler or trailer, or it can be a more permanent land or marine structure. The term "drilling rig" generally refers to equipment commonly used to penetrate the surface of the earth's crust.
[0004] Land or land-based drilling rigs capable of drilling to great depths (e.g., 10,000 meters or more) are typically composed of large equipment. The main components of such drilling rigs may include mud tanks, mud pumps, derricks or masts, winches or lifting equipment, rotary tables or top drives, and drill strings. Large drilling rigs are capable of drilling thousands of meters through the earth's crust, using mud pumps to circulate drilling mud (slurry) through the drill bit and up to the casing annulus to cool and remove cuttings while drilling. The winches or lifting equipment and the derricks or masts with top drives are required to lift and handle hundreds of tons of drill pipe, which form part of the drill string. Such components are typically large out of necessity to bear the weight of the drill string and apply the necessary torque to drill to great depths.
[0005] In view of this, the applicant has recognized that the art needs a drilling device that can drill to a very deep depth, which can also be transported by road and is relatively mobile. In addition, it is also desirable that such drilling devices can be operated autonomously or semi-autonomously.
[0006] The present invention is conceived based on this object. Summary of the invention
[0007] It will be understood by those skilled in the art that the term "truck" as used herein includes in a broad sense any suitable motor vehicle designed to transport goods or carry special loads, including various forms of vehicles used to carry goods and materials, usually consisting of a single self-propelled unit, but also often consisting of a trailer towed by a tractor unit or an associated wheeled frame for transporting heavy objects.
[0008] According to a first aspect of the present invention, there is provided a drilling device, comprising:
[0009] A vehicle-mounted rotating pedestal for placement above a blowout preventer (BOP), the blowout preventer (BOP) being operably mounted in a pilot hole of a well to be drilled;
[0010] A vehicle-mounted drilling mast including a rotary head drive displaceable along the mast to achieve drilling, the drilling mast being engageable with a rotary pedestal;
[0011] a vehicle-mounted drill pipe holder configured to engage the rotary table and selectively grip and hold the drill string;
[0012] a vehicle-mounted drill pipe loading assembly configured to automatically load drill pipe segments into a drilling mast to form a drill string; and
[0013] at least one length of torque transfer rod including a swivel coupling defined adjacent either end thereof, the torque transfer rod being engageable with the drill string;
[0014] The drilling device is configured to drill a well in the following manner:
[0015] i. The drill pipe loading assembly interchanges the drill pipe section with at least one torque transmission rod in the drill string;
[0016] ii. the swivel head drive applies drilling torque only when engaged with the swivel head coupling of the torque transfer rod; and
[0017] iii. The holder holds the drill string to facilitate the interchange of drill rods and torque transmission rods, and to facilitate the movement of the rotary head drive between multiple rotary head couplings.
[0018] As will be appreciated by those skilled in the art, the drilling apparatus extends the drill string into the well by interchanging a drill rod segment with at least one torque transmission rod segment, so that the rotary head drive applies torque to the drill string only when it is engaged with the rotary head coupling of the torque transmission rod segment. The gripper grips the drill string to allow the drill rod loading assembly to be interchanged between the drill rod segment and the torque transmission rod segment to extend the drill string. In this way, a single torque transmission rod segment can be used to drill and extend the drill string. The gripper also grips the drill string to allow the rotary head drive to move from the lower rotary head coupling of the torque transmission rod segment to its upper rotary head coupling when drilling.
[0019] In addition, it is understood that the operation of the drilling device is usually reversible in order to remove the drill string section, ie the drill rod section and the torque transmission rod section, from the well. Therefore, the description of such drilling operation herein includes the reverse order as appropriate.
[0020] In an embodiment, the truck having components mounted thereon, namely, a rotary table, a drilling mast, a drill rod holder and / or a drill rod loading assembly, comprises an automated and / or autonomous platform.
[0021] In an embodiment, the vehicle-mounted components are mounted in a deployable manner, wherein the components can be stowed from a stowed position to reduce the space occupied during transportation, and deployed from a deployed position to perform the described tasks.
[0022] In an embodiment, the drilling mast is pivotally disposed on the truck such that the mast is deployable between a transport position in which the mast is positioned along the truck and a drilling position in which the mast is in a substantially upright position for drilling.
[0023] Typically, the onboard component includes a plurality of stabilizers configured to stabilize the component on the surface to be drilled.
[0024] In an embodiment, the drill rod loading assembly includes a manipulation arm for manipulating a drill rod segment or a torque transfer rod segment and a manipulation mechanism configured to automatically displace, orient and / or rotate the rod segment to engage the drill string.
[0025] In an embodiment, the drilling apparatus comprises an onboard mud system configured to supply drilling mud to the drill string.
[0026] According to a second aspect of the present invention, there is provided a drilling method, comprising the following steps:

[0028] engaging a vehicle-mounted drilling mast with the rotary table, the vehicle-mounted drilling mast including a rotary head drive, the rotary head drive being displaceable along the mast to achieve drilling;
[0029] engaging a vehicle-mounted drill rod holder with the rotary table, the vehicle-mounted drill rod holder being configured to selectively grip and hold a drill string;
[0030] positioning a vehicle-mounted drill pipe loading assembly configured to automatically load drill pipe segments into a drilling mast to form a drill string; and

[0032] i. Interchanging drill pipe segments with at least one torque transfer rod within the drill string through a drill pipe loading assembly, the torque transfer rod including a swivel coupling defined near either end thereof;
[0033] ii. a swivel head coupling that applies drilling torque to the torque transfer rod via a swivel head drive; and
[0034] iii. Through the clamp, the drill string is clamped as needed to facilitate the interchange of the drill pipe and the torque transmission rod section, and the rotary head drive moves between multiple rotary head couplings along the torque transmission rod section.
[0035] In an embodiment, the method comprises the step of supplying drilling mud to the drill string via an onboard mud system.

[0048] The other features of the present invention are described more fully in the following description of several non-limiting embodiments thereof. This description is only used to illustrate the present invention to the skilled person. This should not be construed as a limitation to the summary, disclosure or description of the present invention described above.
[0049] In the accompanying drawings that are combined to illustrate the features of one or more example embodiments, the same reference numerals are used to identify the same components from time to time. In addition, features, mechanisms, and aspects that are well known and understood in the art will not be described in detail because these features, mechanisms, and aspects are within the comprehension of the technician.
[0050] The present invention broadly provides a drilling device 10 that is capable of drilling to considerable depths, such as 10,000 meters or more, but is also transportable and mobile by road. The drilling device 10 illustrated herein is also capable of autonomous or semi-autonomous operation, as will be apparent to one skilled in the art. The drilling device 10 is particularly suitable for use in oil and gas operations and geothermal drilling applications. Of course, other uses are also within the scope of the present invention.
[0051] Referring now to the drawings, there is shown one possible embodiment of a drilling apparatus 10 that may be used to drill a well in the surface 6. In order to provide a drilling apparatus 10 that is capable of drilling to a certain depth, but is road transportable and relatively mobile compared to conventional drilling rigs, the drilling apparatus 10 is composed of a plurality of vehicle-mounted components, as shown and described in more detail below. In one embodiment, such vehicle-mounted parts or components may be deployed above or near the pilot hole 8 of the well to be drilled, typically including a blowout preventer (BOP) 14 or related wellhead components.
[0052] In an exemplary embodiment, as described in more detail below, such vehicle-mounted components are typically mounted in a deployable manner, wherein the components can be stowed from a stowed position to reduce the space occupied during transportation, and deployed from a deployed position to perform the described tasks. The deployment method can vary, and typical examples include hydraulic or pneumatic actuators, electromagnetic actuators, etc. In addition, such vehicle-mounted components are mounted on a truck platform and typically include stabilizers 34, such as hydraulic stabilizer legs, electromagnetically actuated stabilizers, etc., which are configured to stabilize the components on the surface 6 to be drilled. Such deployment and stabilization mechanisms and actuators are known in the art and will not be described in detail herein.
[0053] like Figure 2 As shown, the drilling apparatus 10 includes a vehicle-mounted rotating pedestal 12 configured to be placed above a BOP 14 or related wellhead components. The rotating pedestal 12 may include a stabilizing frame for positioning the rotating pedestal above the BOP 14 as desired to form a stable foundation for drilling operations.
[0054] The drilling device 10 also includes a vehicle-mounted drilling mast 16 including a rotary head drive 18 that is displaceable along the mast 16 for drilling. Figure 3 As shown, the drilling mast 16 is configured to be engageable with the rotating table 12. Such engagement can take a variety of forms, generally mechanical, electromechanical, hydraulic or the like, and will be understood by those skilled in the art. The drilling mast 16 is generally pivotally disposed on the truck carrying it so that the mast 16 is deployable between a transport position and a drilling position, in which the mast is placed along the truck, and in which the mast is in a substantially upright position for drilling. It is noteworthy that the drilling mast 16 is generally compact compared to conventional deep drilling rigs that are capable of drilling to great depths.
[0055] like Figure 4 As shown, the drilling device 10 also includes a vehicle-mounted drill rod clamp 20, which is configured to engage with the rotary work table 12 and selectively clamp and hold a drill string 22, as described in more detail below. The drilling device 10 also includes a vehicle-mounted drill rod loading assembly 24, an example of which is shown in FIG. Figure 5 and Figure 6 , which is configured to automatically load drill rod segments into the drilling mast 16 to form a drill string.
[0056] In an exemplary embodiment, the drill rod loading assembly 24 includes a manipulation arm 36 for manipulating the drill rod segments 26 or torque transmission rod 28 segments and a manipulation mechanism 38 configured to automatically shift, orient and / or rotate the rod segments 26 and 28 to engage the drill string 22. In such embodiments, the drilling device 10 also includes an onboard mud system 40 configured to supply drilling mud to the drill string 22. In this case, the mud system 40 is coupled to the manipulation mechanism 38 forming the end of the drill string 22, as shown.
[0057] As shown in the exemplary embodiment, the onboard components are generally positioned radially around the well, but of course, variations on this are possible and contemplated. In addition, one or more of the onboard components may be located on one or more trucks. For example, the drill pipe loading assembly 24 and mud system 40 of the exemplary embodiment are shared between truck platforms, the drill pipe section supply device 42 and the manipulator arm 36 are on one truck, and the mud system 40 and the manipulator mechanism 38 are on another truck. Again, this is just an example, and variations on this are possible and contemplated.
[0058] Importantly, the drilling device 10 includes at least one length of torque transfer rod 28 including a swivel head coupling 30 generally defined near either end 32 of the torque transfer rod, such as, for example, Figure 7The torque transmission rod 28 is engageable with the drill string 22, which typically comprises drill rod segments, for example, into which the torque transmission rod can be screwed.
[0059] In this way, the drilling device 10 is configured to interchange a drill rod segment 26 with at least one torque transmission rod 28 within the drill string 22 through the drill rod loading assembly 24 for drilling, wherein the rotary head driver 18 applies drilling torque only when engaging the rotary head coupling 30 of the torque transmission rod 28, i.e., no torque is directly applied to the drill rod segment 26 of the drill string 22. Importantly, the rod clamp 20 selectively clamps the drill string 22 to facilitate the interchange of drill rods 26 and torque transmission rod 28 segments on the drill string 22, and to facilitate when the rotary head driver 18 needs to move between multiple rotary head couplings 30 on the torque transmission rod 28 segments.
[0060] Such drilling operations are Figures 8 to 10 1, wherein a relatively short and compact drilling mast 16 having a rotary head drive 18 can be used to drill to considerable depths, the rotary drive head 18 applying drilling torque to the drill string 22 only through a torque transfer rod 28 segment (specifically a rotary head coupling 30). Such torque transfer rod 28 segments are selectively interchangeable with conventional drill rod segments 26 to extend the drill string 22 into the well, but using the rod holder 20, the torque transfer rod 28 segments are used for drilling, but are subsequently removed (when the drill string 22 is secured in place by the holder 20) and replaced with conventional drill rod segments 26.
[0061] In this way, one or more torque transfer rod 28 segments can be used to transfer torque from the rotary head drive 18 to drill the well, so that the rotary head drive 18 does not directly apply torque to the drill pipe segment 26. The torque transfer rod 28 segments are typically made smaller than conventional 12 meter drill pipe segments and more durable, i.e., stronger. This allows the use of multiple torque transfer rod 28 segments for drilling, after which they are removed from the well and conventional drill pipe segments are installed so that the entire drilling assembly can be lowered into the well without directly applying torque transfer to the conventional drill pipe segment 26.
[0062] Such an arrangement allows the components of the drilling rig 10 to be more compact than conventional drilling rigs. In particular, the use of shorter torque transfer rod 28 segments (through which drilling torque is applied to the entire drill string 22) enables the use of a shorter drilling mast 16 while the drilling device 10 is still able to drill to great depths.
[0063] Those skilled in the art will appreciate that the rotary head coupling 30 on the end 32 of the torque transmitting rod 28 segment can take a variety of forms, but is generally configured to allow the rotary head drive 18 to apply significant torque thereto. For example, a slotted keyway or similar mechanical configuration may be used.
[0064] Fig.10 An example of a rod clamp 20 is shown, which is configured to selectively clamp and hold a drill string 22 to facilitate the interchange of drill rods 26 and torque transfer rods 28 segments to the drill string 22, and to move the rotary head drive 18 between the rotary head couplings 30 on the torque transfer rod 28 segments when necessary. For example, when drilling and after the torque transfer rod 28 segments are installed on the drill string 22, the rotary drive 18 engages with the lower rotary head coupling 30 and applies torque to it to perform drilling. As the drill string 22 enters the well, the clamp 20 clamps the drill string 22 once the rotary drive 18 is close to the rotary table 12.
[0065] With the drill string 22 clamped and secured in place, the swivel head drive 18 can be disengaged from the lower swivel head coupling 30 and moved back onto the mast until it can be connected to the upper swivel head coupling 30 to continue drilling. Once such a drilling cycle is completed, the drill string 22 can be pulled out of the well so that the torque transmission rod 28 segment is removed and replaced with a conventional drill rod segment 26, and the drill string 22 is lowered into the well again, after which another such drilling cycle can be repeated until the desired drilling depth is reached.
[0066] Importantly, in embodiments, the drilling apparatus 10 is capable of being automated or becoming autonomous. For example, a truck on which the components are mounted, i.e., the rotating table 12, the drilling mast 16, the drill rod holder 20, and / or the drill rod loading assembly 24, may include an automated and / or autonomous platform, such as an autonomous vehicle. Similarly, all of the corresponding components of the drilling apparatus 10, i.e., the rotating table 12, the drilling mast 16, the drill rod holder 20, and / or the drill rod loading assembly 24, may be automated or autonomous, wherein such components function in a complementary manner to perform a drilling cycle as desired.
[0067] Accordingly, the drilling device 10 may include a suitable controller and associated control network (not shown), through which the operations of the various components may communicate signals and synchronize signals to achieve such automated and / or autonomous operations. Such automation is known in the art and the specific details will be within the scope of understanding of the technician.
[0068] In view of the above, the present invention also includes a related drilling method, which generally includes the following steps: positioning a vehicle-mounted rotary table 12 above a blowout preventer (BOP) 14, which is installed in a pilot hole 8 of a well to be drilled, and engaging a vehicle-mounted drilling mast 16 with the rotary table 12, the drilling mast including a rotary head drive 18, which is displaceable along the mast 16 for drilling. Then, the method includes the step of engaging a vehicle-mounted drill pipe clamp 20 with the rotary table 12, the drill pipe clamp being configured to selectively clamp and hold a drill string 22.
[0069] The method then includes the steps of positioning an onboard drill pipe loading assembly 24 configured to automatically load sections of drill pipe 26 to the drilling mast 16 to form a drill string 22 and drilling by executing the components of the drilling cycle as described above.
[0070] Specifically, such drilling steps or drilling cycles generally include: exchanging between drill pipe segments 26 and at least one torque transfer rod 28 within the drill string 22 through a pipe loading assembly 24, the torque transfer rod including a swivel head coupling 30 defined near either end 32 thereof; applying drilling torque to the swivel head coupling 30 of the torque transfer rod 28 segment through a swivel head driver 18; and, when necessary, clamping the drill string 22 through a clamp 20 to facilitate the interchange of the drill pipe segments 26 and the torque transfer rod 28 segment, and, when necessary, moving the swivel head driver 18 between the upper and lower swivel head couplings 30 of the torque transfer rod 28 segment.
[0071] In one embodiment, the method further comprises the step of supplying drilling mud to the drill string via an onboard mud system 40 .
[0072] Applicants believe that the present invention is particularly advantageous in providing a drilling apparatus 10 and associated drilling method that utilizes specific components and drilling techniques, using specially configured torque transfer rod 28 segments to allow drilling to great depths, while being road transportable and relatively mobile compared to conventional deep drilling rigs. In particular, by utilizing the torque transfer rod 28 segments, conventional high mast structures become redundant. Furthermore, the operation of the drilling apparatus 10 may be automated and / or autonomous.
