Description

BACKGROUND OF THE INVENTION

This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.

This present disclosure relates to pipe handling equipment used on various drilling rigs, like jackup rigs, semisubmersible rigs, drill ships, or land rigs, and, in particular, to fingerboards.

Drilling tubulars include drill pipe, tubing, and casing (“tubulars”). Drilling tubulars are assembled by threading one section of tubular to the next. Management of tubulars on the drill floor is conducted by various pipe handling components and features that retrieve a tubular, position the tubular into the mousehole, and tighten one tubular to the next.

One of these handling components is the fingerboard. During well operation, it is common for the drill string to be pulled from the bore to facilitate changing of the drill bit or for other reasons. The drill pipe is pulled from the bore and a stand is unthreaded from the drill string. The upper end of the stand is disconnected from the traveling block. The upper end of the stand is placed between a set of racking fingers on a fingerboard which support the stand in a substantially vertical position.

A typical fingerboard includes slots defined by beams known as fingers. A multiplicity of latches are arranged on each finger. Latches are positionable between a horizontal orientation and a vertical orientation. A space is defined between adjacent fingers and adjacent horizontally oriented latches for receiving a single stand of drill pipe. A latch is positioned between each stand of drill pipe. The latches are typically pneumatically operated.

SUMMARY OF THE INVENTION

This summary is provided to introduce a selection of concepts that are further described below in the detailed description. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining or limiting the scope of the claimed subject matter as set forth in the claims.

A land rig includes drilling equipment for drilling a subterranean well and for producing hydrocarbon-bearing fluid from a subterranean rock formation. The land rig includes tubular handling equipment, a controls skid to power and functionally control the drilling and pressure control equipment, a pressure control system like a blowout preventer (BOP) for controlling pressure of the well and a manifold system to direct and manage fluids to and from mud pumps.

The various equipment and tools of the rig may be monitored and controlled from a drilling control room (DCR), located on the rig floor.

A multi-part fingerboard is provided for use when there is a requirement for both drill pipes and casing pipes. The disclosed fingerboard might also be used for offshore rigs, such as platform rigs, MODU's (jack-ups, semi submersibles, drill ships, etc.).

In one embodiment, the fingerboard of the invention is a 2-in-one fingerboard that can hinge around a support and quickly be converted from a drill pipe fingerboard to a casing fingerboard—or the other way around.

In embodiments of the disclosure, the finger board can be used with various types of pipe rackers, such as Cameron® SmartRacker™ (x-y Racker), or a parallel racker or a bridge racker as well as a so called 2-Arm System.

The disclosed fingerboard enables a quick change from a fingerboard that is configured for drill pipe to a fingerboard that is configured for both drill pipe and casing.

The quick change is achieved by assigning part of the fingerboard to both drill pipe and casing with a hinged section. In embodiments, the fingerboard has a movable section with two fingerboard portions installed as an angled assembly, e.g., a 90 degrees assembly where one portion of the 90 degree assembly is configured for drill pipes and the other portion of the 90 degree assembly is configured for the chosen casing size (for example 9⅝″). Capacity of the various tubular sizes might be adjusted when the fingerboard(s) is designed or as desired.

In embodiments, the movable section includes two “halves” that are activated by a rotating device or mover, e.g., a hydraulic cylinder. The mover may be remotely operated from a drilling control system. The control system may also be able to interface with the controls for a pipe handling system in such a way that the pipe handler might be configured according to the fingerboard configuration being used.

In embodiments, part of the fingerboard might be “hinged”. The “hinged” part of the fingerboard might be configured for drill pipe and the other “half” of the hinged fingerboard might be configured for casing. In embodiments, controls might be integrated (into the rig control system) to automatically control the fingerboard (casing or drill pipe configuration). In embodiments, controls might be integrated to position and reach of the pipe racker.

According to some embodiments, it is disclosed a fingerboard that can handle both casing and drill pipes.

In greater detail, in one embodiment, the fingerboard of the invention includes a fixed fingerboard section and a movable fingerboard section.

The fixed fingerboard section has a drill pipe receiving space for receiving a tubular having a drill pipe diameter. The fixed fingerboard section has at least two fingers defining a slot, the fixed fingerboard section having a plurality of latches arranged between the fingers for defining the drill pipe receiving space. Each latch of the plurality of latches of the fixed fingerboard section is selectively movable between an open position and a closed position.

The movable fingerboard section has a first pipe receiving portion defining a first pipe receiving space and a second pipe receiving portion defining a second pipe receiving space.

The first pipe receiving portion has at least two fingers defining a first pipe receiving slot and a plurality of latches arranged between the fingers for defining the first pipe receiving space for receiving a first pipe having a first diameter.

The second pipe receiving portion has at least two fingers defining a second pipe receiving slot and a plurality of latches arranged between the fingers for defining the second pipe receiving space for receiving a second pipe having a second diameter.

The first pipe receiving portion and the second pipe receiving portion are offset at an angle, e.g., wherein the angle is at least 90 degrees. In one embodiment, the angle is 90 degrees. In one embodiment, when the first pipe receiving portion is vertical, the second pipe receiving portion is horizontal and when the second pipe receiving portion is vertical, the first pipe receiving portion is horizontal.

The first pipe receiving space may be the same size as drill pipe receiving space. The the second pipe receiving space may be larger than the first pipe receiving space. The second pipe receiving space is sized to receive casing.

A hinge is connected to the first pipe receiving portion and the second pipe receiving portion of the movable fingerboard section for selectively positioning the movable fingerboard section in a first position wherein the first pipe receiving portion is adjacent the fixed fingerboard section. The hinge additionally facilitates selectively positioning the movable fingerboard section in a second position wherein the second pipe receiving portion is adjacent to the fixed fingerboard section. The hinge may be horizontally oriented.

The first pipe receiving space is a different size than the second pipe receiving space for receiving tubulars of different diameters.

A mover is affixed to the movable fingerboard section for moving the movable fingerboard section into the first position and into the second position. The mover may be a hydraulic cylinder. The mover is activated by controls. The mover may be controlled via a control system, wherein the controls of the mover interface with controls of a pipe handling system.
