Abstract
A coiled tubing support guide for maintaining an arch in a length of coiled tubing as it is unwound from a storage reel and feed into a coiled tubing injector connected with a wellhead is mounted to an elongated support structure rather than to the coiled tubing injector. The elongated support structure bears a load created by tension placed on the coiled tubing by the reel, thereby avoiding putting a bending moment on the wellhead. In an alternate embodiment, a coiled tubing injector being held by a hoist line from the elongated support structure is coupled to the elongated support structure with a bending-resistant coupling that permits relative rotation of the coiled tubing injector.

The cross reference of related application
This application claims U.S. Provisional Application No.61/583, the priority of 230, this application is filed on January 5th, 2012, its full content by being incorporated in this, for all objects.
Technical field
The present invention relates generally to the oil field operation using coiled tubing/coiled tubing.
Background technology
Coiled tubing is widely used in oilfield services and operation usually.Relative to straight conjugation tube, it can run with two-forty and enters wellhole and enhance from wellhole, and unlike wire rope (wire line), it can be pushed in wellhole.Coiled tubing refers to a continuous print steel pipe, is namely wound into large take-up reel by continuous print milling, for transport and process.At diameter from 0.75 inch to more than 4 inches, coiled tubing can have from 50,000 ft lbf per square inch (PSI) to more than the surrender of 120,000PSI and hot strength, and manufactured go out length be greater than 30,000 foot.Such as, it can be used for boring, but it more after drilling well of being everlasting for logging well, well-flushing, pressure break, well cementation, salvaging, completion and to produce relevant operation.
Coiled tubing uses the machine being referred to as coiled tubing injector to run and enters wellhole and shift out from wellhole.Name " coiled tubing injector " stems from the following fact: in the wellhole be pre-existing in, oil pipe may need to be forced to by sliding seal or in " being injected into " well, to overcome the fluid pressure in well, until the power that the pressure that the weight of oil pipe in well exceedes the cross section acting on oil pipe produces.But once the weight of oil pipe has exceeded this pressure, it must have been kept by injector.
There is many dissimilar and coiled tubing injectors that is structure and can process the coiled tubing used in oil field operation.Most of coiled tubing injector has head, and this head is made up of two continuous print chains, and each chain is contained on the many groups of sprocket wheels separated, and makes the chain length that there is extension between sprocket wheel.At least one chain is driven by motor---normally hydraulic pressure, although the motor of other types can be used---this motor is connected to one or more sprocket wheel.The coiled tubing that chain is arranged to make to enter injector is remained between chain by the fixture being installed to each chain.Fixture is pressed against the external diameter of oil pipe, produces the frictional force being parallel to the axis of oil pipe thus.This frictional force directly associates with the normal force applied by fixture.
Fig. 1 and Fig. 2 shows after rig is removed, the example of normally used equipment when carrying out operation to the well got out before.The reel 10 of coiled tubing is arranged on trailer 11, for being transported to scene.Coiled tubing injector, control cabinet and other the equipment for injector running are also sometimes referred to as " coiled tubing unit ", and are usually indicated by the reference number 12 in figure.When coiled tubing 14 launches from reel, or when being wound backrush cylinder, it is by the chain of the directed aligning coiled tubing injector of oil pipe support guide part 16.Because such guide normally arch, therefore they are sometimes referred to as " gooseneck " support member.When coiled tubing injector is arranged, guide is connected to the framework of coiled tubing injector, and when being operated with convenient injector, guide and coiled tubing injector have fixing relation.Usually, guide arch to be located or be oriented in it to rotate between chain, make coiled tubing penetrate the top of injector head, or the optional top in injector head, coiled tubing is penetrated be installed to the straightener of framework, for eliminating the bending of oil pipe before entering injector head.(as used in this manual, " coiled tubing injector " refers to the injector head having or do not have straightener, unless otherwise indicated by context.) when it is untied or is wound around, in order to coiled tubing is wrapped on reel and in order to keep the coiled tubing be wrapped on reel, reel must maintain the tension force on coiled tubing.Arch is guided to prevent coiled tubing to be applied to the tension force on oil pipe by reel and the warpage that produces or otherwise damage.But guide arch to be usually attached on the framework of coiled tubing injector in the following manner, namely which allows it to be attached or to be connected to different positions or orientation.Such as, preferably location or orientation can be depending on the diameter of used oil pipe and oil pipe is lowered or pushes wellhole or is drawn out wellhole.When oil pipe departs from reel, it has than relatively larger the bending when it is drawn out from well, and this may affect and guide arch how to be fixed to injector.Therefore, " fixing relation " does not imply that it does not allow adjustment.
When utilized, coiled tubing injector is positioned at above well head, be high enough to the miscellaneous equipment holding one or more blowout hookup 20, standpipe (riser) 22 and can be connected to well head, wherein before entering wellhole, coiled tubing must by this well head.Standpipe is made up of one section or more section straight tube, and extends from the blowout hookup being attached to well head.Before being lowered in wellhole, standpipe is used for holding the instrument that is elongated, rigidity of the end being attached to coiled tubing.Coiled tubing injector is connected to the standpipe with blowout prevention box (stripper), and this standpipe coiled tubing is pushed into by this blowout prevention box or is pulled out.Because do not have mast or platform, the temporary structure set up above well head or be urged to on-the-spot mobile job crane, is used to location and keeps injector in place.
Fig. 1 shows the example of the use of portable construction 24, its by be delivered to on-the-spot one or more can stacked segments by temporary erection, for keeping coiled tubing injector in place above well head.Fig. 2 illustrates the use of high power capacity, self-propelled crane 26, to promote between well maintenance operational period and keep coiled tubing injector 18 and guide arch in position.Crane be usually placed on the well head of coiled tubing reel 10 opposite face or, if necessary, be placed on side.Some or all weight of injector and oil pipe are transferred on the arm of crane.But, between coiled tubing injector 18 and reel 10 coiled tubing part 14 in tension force also guiding arch 16 on apply lateral force, this power is transferred into coiled tubing injector 18, thus causes the moment of deflection on well head.More and more for holding the higher well head of long downhole tool and larger-diameter coiled tubing, mean larger moment of deflection.Structure 24 can be designed as the load of process desired by moment of deflection.But when crane, craneman must carry out manipulating crane in the mode applying reaction force on coiled tubing injector 18.This reaction force usually by pulling back and applying away from reel 10, thus attempts the tension load reducing the moment of deflection produced on well head.Know that retracting how difficult being usually directed to of tubing injector guesses, and in some cases, the tension force on oil pipe can exceed the capacity of crane to keep lateral force.Therefore, there is many examples, be wherein pulled through well head and crane collapses.
Summary of the invention
Along with the increase of the diameter of the coiled tubing be used in oil well operation, wall thickness and yield strength, will the tension force of larger coiled tubing be needed to be wrapped on holder.Reel forces need the part of the coiled tubing extended between reel and coiled tubing injector on larger tension force.In addition, larger oil pipe also needs higher well head.Larger tension force and the well head of Geng Gao cause the larger moment of deflection putting on well head.
Carry out in an example of the method and apparatus of well maintenance operation at use coiled tubing, coiled tubing guide when entering the top of coiled tubing injector for supporting coiled tubing is fixed to the braced structures above coiled tubing injector, and can not be fixed to coiled tubing injector.The load caused by the tension force on coiled tubing transfers to braced structures instead of coiled tubing injector by coiled tubing guide.Therefore, the tension force on reel no longer causes the moment of deflection in well head.The moment of deflection that larger tension force is applied to coiled tubing by reel and need not increases on well head.
In another example, be sent to coiled tubing injector with this guide from reel, for keeping the arm of the crane of the coiled tubing injector above well head and matching for the oil pipe guide supporting coiled tubing.Alternately, the coiled tubing guide above coiled tubing injector located by crane or extensible mast, and coiled tubing injector is kept by independent crane.
In another example, reel is located relative to elongated braced structures (such as crane arm or scalable mast), and the most of load caused by the tension force on coiled tubing is mainly born by elongated support member as axial compressive force.Although bending load is also applied in elongated braced structures, it is upwards to a certain extent, if but it is supported by elongated braced structures, then its is revolted and the mast that caused by coiled tubing injector is bent downwardly load, and the weight of elongated braced structures.Bringing out the axis of load and elongated support structure by closer aliging, being reduced with the conjecture of offsetting load relevant with this structure of operation (particularly crane).
In another example, coiled tubing guide uses and is attached to crane arm or scalable mast for allowing it to tilt and/or rotating side to the connector of opposite side.This adjustability allows coiled tubing and the angle of carrying between elongated component that coiled tubing supports boom angle changes, and allows the greater flexibility when the elongated braced structures in location and reel thus.
Carry out in the alternate embodiments of the method and apparatus of well maintenance operation at a kind of coiled tubing that uses, injector with coiled tubing guide hangs on crane arm, scalable mast or other elongated braced structures, and coupled with between the moving period of the coiled tubing injector above at least well head by the end of connector and elongated braced structures, allow the relative rotation relative to the coiled tubing injector of crane and opposing is simultaneously bending.Coiled tubing guide is not installed to the end of crane.Connector prevents the moment of deflection being applied to well head due to the tension force of coiled tubing.

Detailed description of the invention
In the following description, identical numeral refers to identical element.
In each example of Fig. 3-17, for by coiled tubing 34, the coiled tubing injector 18 injected in wellhole utilizes elongated braced structures to be positioned at the top of well head.The example of braced structures elongated like this comprises the crane 26 with telescopic hoist boom 38.Another example of braced structures elongated like this is extension mast 60, as shown in figs. 9-10.
Coiled tubing unit generally includes framework 18a, and coiled tubing injector head 18b is installed to this framework 18a.Such as, but in other embodiments, coiled tubing injector can comprise more multi-part, comprises straightener.In other embodiments, this unit can omit external frame, as framework 18a.In the example of Fig. 3-14 and 16-17, coiled tubing enters the straightener 19 at the top of the framework 18a being arranged on coiled tubing injector 18.Not shown straightener in the embodiment of Figure 15 A-15C, but such embodiment can be suitable for accommodation one.Oil pipe leaves straightener and enters the top of coiled tubing injector head.In this example, coiled tubing injector head 18b is formed by for a pair relative cycle with clamper (not shown) (endless) chain be delivered into by oil pipe and go out well head.When being lowered in well, coiled tubing 34 is fed to standpipe 22 from reel 10.Elongated braced structures (arm 38 or extension mast 60 as crane) is for locating the coiled tubing injector 18 above well head.Coiled tubing injector is hung by the main hook 42 be connected with the head 40 of elongated braced structures by main increase line 44.The motion up and down of main hook 42 is guided by main increase line 44.The head 40 of elongated braced structures generally includes wheel or the pulley of at least one sheave 45 or other other types, and this is taken turns and is rotatably installed on axle, takes turns operation increase line around this.
Coiled tubing 34 is at one end wrapped in holder (not shown), reel 10 as in Figure 1 and Figure 2.Upwards route (route) is to coiled tubing guide from holder for the other end, and in this example, this guide is made up of arch support guide 36, and it is sometimes referred to as gooseneck.When guide becomes the top of coiled tubing injector, the radius of arch support guide 36 supports coiled tubing 34, thus allow the direction of coiled tubing 34 from the upward direction of holder to change in downward direction, to be received in the top of coiled tubing injector 18.Under the tension force of reel, the radius of arch or curvature allow the change on direction, and without warpage or other excessive damage coiled tubing.(note, when being wound around from reel and untiing or alternate manner little by little bends some circles, coiled tubing is designed to plastic deformation.)
According to specific embodiment, arch support guide 36 can also comprise a series of roller, to reduce and the frictional force of coiled tubing along with when arch support guide 36 moves at coiled tubing.In the embodiment shown in fig. 3, arch support guide 36 be usually configured to higher than arm 38 and with arm 38 in line.Aim at the arm axis of arm, the line of the power caused by the tension force of coiled tubing is roughly aimed at the axis of the arm of crane, thus cause that most of load is carried by arm as axial load and any remaining load causes moment of deflection.
(comprise shown in Fig. 3) in the embodiment shown in multiple accompanying drawing, coiled tubing support guide part is attached to the arm of crane by adjustable connector 46.Alternately, coiled tubing support guide part is attached to arm in the following manner, and namely which does not allow coiled tubing support guide part position or orientation to be adjusted, and to make when this guide is attached the central axis of itself and arm have fixing relation.Such as, the central axis of the planar alignment arm of oil pipe support guide part or the angle that becomes to fix with the central axis of arm.In certain embodiments, coiled tubing support guide part (as shown in Figure 3) is knock-down or removable from the arm of crane or other elongated braced structures, to allow easier transport.
Adjustable connector (as connector 46) allows the position of the coiled tubing support guide part of arch support guide or any other type to adjust along multiple axis.Such as, adjustable connector can allow arch support guide 36 to adjust by tilting forward and backward.Allow to control better the route of coiled tubing like this and provide the adjustability of the angle of the arm 38 relative to coiled tubing.In another embodiment, adjustable connector can allow coiled tubing support guide part move or swing to opposite side from the side of arm and/or rotated, and makes the axis of the plane of coiled tubing support guide part and arm at angle.This ability allows the position of crane 26 to be changed relative to coiled tubing unit 12.Such as, if oil pipe guide rotates about 30 degree, crane 26 generally can be located along the side of coiled tubing unit 12.The multiple positions allowing ground installation (coiled tubing unit and crane and/or extension mast) can be favourable, there is the place of other restrictive condition when especially the surrounding of well head exists the location of the interstitial radii of reduction or equipment.
Fig. 4 A, Fig. 4 B, Fig. 4 C and Fig. 4 D show the representative illustration of the basic element of character of connector 46.Although be shown and described with reference to the arch guide of the one end being arranged on arm, mast or other elongated braced structures, but this connector can be suitable for the coiled tubing braced structures of other type, such as shown in those relevant with other accompanying drawings and described.In this example, connector allows to rotate up and down, and with pivotable or the either side swinging to arm, and rotation makes the plane at coiled tubing support guide part line place can be adjusted and be placed with the axis of arm is angled.In this example, connector comprises three joints 47,49 and 51 represented by pin, and Parallel offset connecting rod 53, it allows oil pipe support guide part around approximate horizontal axis (first axle) pivotable up and down, rotate around the second axis or rotate, and in general, (position according to the first joint 47) this connector is swung to opposite side around the 3rd axis being roughly parallel to the second axis from side by orientation vertically.
Fig. 5 A and Fig. 5 B shows another representative illustration connector 55, and this connector is similar to connector 46, but it does not swing to opposite side from side.It eliminates joint 51 and offset conn rod 53, and is connected to joint 49 with arch support guide.Therefore, this connector is only adjustable in two degree of freedom: the joint 47 that it is formed round pin moves up and down, and rotates or pivotable around the joint 49 that pin is formed.Although for the sake of clarity omit, in fact, connector (as connector 46 and 55) can have for guaranteeing that joint is locked into place or stops the add ons of rotation when oil pipe runs.In addition, can by the position using the positioner of hydraulic cylinder or other type remotely to control joint.
Although not shown, other example of connector allows oil pipe support guide part only at the enterprising Row sum-equal matrix of one degree of freedom, or more than the enterprising Row sum-equal matrix of three degree of freedom.
In the mode shown in Fig. 4 A-D or Fig. 5 A-B, coiled tubing support guide part is coupled to elongated braced structures (as arm 38) and allows the reel of coiled tubing to be placed on the either side, or above of the elongated braced structures of crane, extension mast or other type below.When coiled tubing 34 is tensioned, tension load is transferred into the arm 38 of crane 26, and is not applied on the coiled tubing injector 18 that hangs on above wellhole.Therefore, tension load can be received independent of coiled tubing injector 18.In addition, be the coiled tubing guide part supports of arch support guide 36 when substantially aiming at the arm 38 of crane in this example, if be applied to advocating to the axial force of arm 38 on crane due to tensioning coiled tubing.Therefore, crane 26 is more easily controlled, and do not need craneman to adjust or mobile arm to offset load.If arch support guide 36 is positioned such that the load force caused by the tension force in coiled tubing is not aimed at the axis of crane arm 38 or other elongated braced structures, this elongated braced structures may be subjected to upwards with the moment of deflection of side direction.But most of crane and other elongated braced structuress can process some lateral loads.Alternately, if crane can process transverse direction caused by the tension force of coiled tubing or lateral load, crane or other elongated braced structuress can be positioned around well head Anywhere.
Fig. 6 A and Fig. 6 B is front elevation drawing and the lateral view of the alternate embodiment of the configuration of equipment for running coiled tubing in wellhole.This embodiment illustrates the arch support guide 36 being similar to the guide shown in Fig. 3.But in this embodiment, arch support guide 36 is fixed or is arranged on the side of arm 38 of crane.Although bias configuration can produce moment of deflection in crane arm 38, the most of loads on arch support guide will be passed to arm as axial load.Be similar to the straight embodiment shown in Fig. 3, tension load can not be delivered to coiled tubing injector 18 and well head.Such as, arch support guide can be attached to arm by connector, and this connector allows it to tilt forward and backward and rotates, and is similar to the embodiment shown in Fig. 3.But due to the configuration of the oil pipe guide on the side of crane arm, connector allows the ability rotated may be limited by arm 38.
Fig. 7 shows alternate embodiment, wherein rotatably takes turns 50 and is used as oil pipe support guide part instead of arch support guide 36.Rotatable wheel 50 is fixed to the head 40 of the arm 38 of crane in Fig. 7, and is usually placed on the top of arm 38.When coiled tubing 34 changes it from the direction that holder departs to direction in downward direction, rotatable wheel 50 supports coiled tubings 34, can be received in the top of coiled tubing injector 18 at described coiled tubing in downward direction 34.The radius of rotatable wheel produces enough arches to allow the change in direction in coiled tubing 34.But radius is enough large, make coiled tubing can not warpage or otherwise damage.As the arch support guide of Fig. 3, wheel 50 passes through for allowing its position or the controlled connector 46 of orientation to be attached to arm.Such as, be similar to Fig. 4 A, Fig. 4 B, Fig. 5 A and the connector shown in Fig. 5 B and the position of wheel and the adjustability of aligning can be provided, the degree of freedom of such permission some, namely can wheel and the central axis of the arm of crane are angled places holder for coiled tubing to the side of crane or opposite side by allowing.But alternately, wheel can be installed by this way, namely wheel has fixing relation with the central axis of crane.
As shown in Figure 8 A and 8 B, rotatable oil pipe guide 50 is alternately attached to the side of crane arm 38 or other elongated braced structures (such as extension mast).
With reference to Fig. 9, in another alternate embodiment, coiled tubing guide member arrangement can be placed on extension mast, and this extension mast is another example of elongated braced structures.In this example, extension mast 60 supports rotatable oil pipe support wheel 50, as shown in Fig. 8 A and Fig. 8 B.Rotatable wheel also can be installed to mast 60 in the mode being attached to crane arm 38 in a kind of Fig. 7 of being similar to.Be similar to crane arm 38, extension mast 60 will mainly stand the tension load caused by coiled tubing 34.Neither coiled tubing injector 18, the load of signal portion neither be stood by well head.In certain embodiments, extension mast can be mobile, and is installed on vehicle (as trailer 62), as shown in the figure.
Referring now to Figure 10.In this embodiment, extension mast 60 supports arch support guide part 36, and this arch support guide utilizes the connector 46 of Fig. 7 shown type to be installed to the head of extension mast 60, is adjusted to allow it.In this example, it can adjust in the description as relevant with Fig. 5 B with Fig. 4 A-D or Fig. 5 A.But as in the embodiments of figure 3, connector can allow to adjust in one or more degree of freedom.In this embodiment, crane 26 is positioned in the opposite of extension mast trailer 62 and reel 10 (it is a part for coiled tubing unit 12), and supports coiled tubing injector 18.But it can be positioned near well head Anywhere.In this example, extension mast 60 is only used for supporting and location coiled tubing support guide part, as arch support guide 36.In alternative embodiments, injector 18 hangs by mast 60 and does not need crane.Should be noted that, independent crane or other lifting can be adopted with other shown embodiment with bracing or strutting arrangement to support coiled tubing injector 18 described in the disclosure, and coiled tubing support guide part is attached to independent elongated braced structures (as crane arm 38 or extension mast 60), it is arch support guide 36 or rotatably takes turns the support guide part that 50 (one as shown in Figure 7) are still suitable for other type of coiled tubing.
