Description
SPECIFICATION MItiple line work performing apparatus
Work perforrmed'irz oil and gasweFl completions and/orworkoveroperations- gl.erieraUV use a conventional TFL pumpdown system or a wire line vertical entry system which requires a floating rig or a fixed structure. The work includes completion, cleanup, testing and other normal work associated with the use of subsurface equipment. However, these conventional techniques all present problems.
In pumpdown systems used in subsurface wells, two tubing strings are required oracommunication betweenthetubing and the annulus requiring a down hole device to be opened and closed remotely to afford communication. These communication devices and the multiple strings restrict development of hydrocarbon reserves due to economic impact. The complexity of these completions reduce the safety of the overall system as two of everything is required.
Avertical entry system with only a single conduit allows development of more hydrocarbon reserves by improving completion economics plus affording greater safety.
The ideal completions would provide maximum economy and safety, plus minimum operational problems. Platform orsubsea completions with single well-conduitthusly appear optimum. The subsea well should have vertical entry for use ofthe present invention.
The present invention is directed towards providing a means of servicing any type of well in an economic and safe manner. The present invention also provides a sound and safe alternate to conventional service techniques such as fishing in vertical entry single conduit wells when wireline techniques have failed, or enhancing pump down operations as a second method of performing work after the primetechnique has failed.
The present invention is directed to a work performing apparatus controlled bya pluralityofcontrol lines which is able to travel up and down a well conduit to perform a variety of completion andworkoverfunc- tions in an oil and/or gas well.

One or more means is connected to the control lines for moving the lines and body through a well conduit.
Anchoring means are provided in the body and actuated from the control lines for holding the body to the well conduit, and work performing means is connected to the body and actuated from the control lines for performing work in the conduit.
A feature ofthe present invention is wherein the meansfc craovy tEre lines intil;e bodythrou:ghthe cn.dii;t inucle propulsion means acting against the inside of the conduit.
Yet a further feature ofthe present invention is wherein the work performing means includes means forperforminglongitudinal movementsand/ormeans for performing rotational movement.
Still afurtherfeatureofthe present invention is wherein the control lines are hydraulic lines.
Anotherfeatureof the present invention is the provision of packoff means on the body actuated from the control linesfor sealing the interior of the conduit.
The present invention is also directed to the provision of a multiple line operated work performing apparatusforuse in awell conduit comprising a body with a plurality of hydraulic control lines connected to the body for operating a plurality offunctions.
Preferably the control lines are pairs of hydraulic lines.
A plurality of propulsion means is connected to the control lines for moving the lines in the body through a well conduitand releasable anchoring meansare provided in the body actuated from one of the control lines for releasably holding the body in the well . Piston and cylinder means are provided in the body actuated from one ofthe control lines for performing longitudinal work movements in the conduit.
Other and further objects, features and advantages will be apparent from thefollowing description of a presently preferred embodiment ofthe invention, given for the purpose of disclosure and taken in conjunction with the accompanying drawings in which
Fig. lisa schematic elevational view of a surface operated subsurface well system,
Fig. 2 is an enlarged elevational view, partly in cross section, illustrating one type of propulsion device for use in the present invention, and Figs3A and 3B are continuations of each other and are elevational views, partly in cross section, illustrating one type of multiple line work performing apparatus according to the present invention.
Referring nowto the drawings, and particularly to
Fig. 1, a surface operated subsurface well system is generally indicated bythe reference numeral 10, here shown as being an offshore system for purposes of illustration only asthe present invention is applicable to land systems.
The system 10 includes a central substation platform generally indicated by the reference numeral 11 in which one ormore lines orconduits 12 and 14 are directed downwardly to a subseawell generally indicated by the reference numeral 16 having a well conduit 18 leading to a production zone 20. The conduit 18 includes varioustypes of well equipment such as a conventional well packer 22 which may be of any suitable types such as CamcoType HSP, a side pocket mandrel 24 such as Camco Type KBM, and a conventional safety valve 26 such as the Camco Type
TRDP. The various well equipment 22, 24 and 26, as well as other types ofwell equipment, may require actuation by a suitable work performing apparatus for performing various operations therein.
The conventional method of performing completion and/orworkover operations is the use of a pumpdown system which in the system 10 would require and additional line from the platform 11 in communication with the conduit t8 or in the case of atypical wire line unit woutd require having a rig on the platform 11 or a workover boat.
The present invention is embodied by a multiple line operated work performing apparatus generally indicated by the reference numeral 30 which is capable of
performing various subsurface completion/workover functions in the conduit 18 and which is moved through the lin-es 12 and 18 by one or more multiple propulsion units generally indicated by the reference numeral 32 which are connected to the apparatus 30 orto a multiple control line bundle 34 which is connected to the apparatus 30 for operating a plurality of functions.
The work performing apparatus 30 maythus be moved through the well conduit and be actuated by the hose bundle 34to provide a large variety of operations without theuse of a drill ship orworkover boatassistanceorwithouthaving an additional parallel conduit such as in pumpdown operations.
Referring now to Figs 3A and 3B, an enlarged representation ofthe work performing apparatus 30 is best seen moving through a well conduit 18 and connected to a multiple line bundle 34 which consists of a plurality of lines connected to the apparatus 30 for operating the apparatus 30.
The apparatus 30 includes a body 36 and preferably suitable anchoring means in the body 36which is actuated by one or more ofthe control lines inthe multiple line bundle 34. For example, slips 38 are provided on the body 36. The slips 38 coactwith a taperedsurface 40 on the body 36 and a tapered surface42on apiston member44.When hydraulic fluid is applied to one ofthe lines, such as46 which supplies pressure to a port 48, the piston member44 movestowards the slips 38 cammingthem out into engagement with the interior ofthe conduit 18 for releasably holding the body 36to the well conduit 18.
The slips may be released by releasing the pressure in line 46 and applying pressure to line 50 and fo a port 52 acting on a piston 54 which is connected to the piston member44. The application of hydraulic pressure againstthe piston 54 moves the piston member 44 downwardly retracting the slips 38. While the anchoring means disclosed have been shown as slips, other types of anchoring or holding means such as dogs or keys engageable in a recess in the conduit 18 may be utilized for the purpose of anchoring the operating tool 30 to the wall ofthe conduit 18 for performing subsurface operations.
In someoperations, it is desirable to packoff or seal the bore of the conduitwith a suitable sealing element.
Therefore,the tool 30 includes a packing element 56 mounted on the body 36 and abutting a fixed shoulder 58 at one end and a movable shoulder 60 at a second end. One ofthe control lines is provided in communication againsta piston 62 which isconnectedto the movable shoulder 60 for compressing the sealing element 56 outwardly into a sealing contact with the interior ofthewall ofthe conduit 18. A releasing control line 64 is connected through a port 66to the
second side of the piston 62 forthe purpose of
retracting the movable shoulder 60 and releasing the
setforce on the seal element 56.
Manytypes of operations in a subsurface well
require a longitudinal work movement. Therefore, a tool attachment such as an axially extending mandrel
70 may be provided in the body 36 four longitudinal
movement downwardly and upwardly and is con
nected to a piston 72. One side of the piston is
connected to a port 74 and the second side of the
piston is connected to a port76, each ofwhich are connected to one ofthe control lines in the bundle 34 for longitudinally moving a mandrel or tool attachment70 upwardlyand downwardly. Asshown in Fig.
3B, a tool 78 such as a paraffin cutter is shown, for cutting paraffin outofthewell conduit 18 as it is longitudinally reciprocated. While the particular tool illustrated is a paraffin simper, othertypes oftools may be used for performiregi longitudinal operations such as shifting a sleeve, baiflng sand, changing out gas lift valves, locking out saefy valves, pulling or running locks, plugs and chokes.In addil-ron,thereane many othertypes of operations that maybe performed in a subsurface well relying on a work performing apparatus providing longitudinal motion In the event that rotational movement is required for performing some operative work, rotatiogrofthetadi holder70 may be provided by a rntativemotorsuch as a vane motor 80 having a first side 82 in communication with one ofthe control lines and a second side 84 in communication with a second control line in the bundle 34.Therefore, the work performing apparatus can generally be used to perform any subsurface work now performed with pumpdown, slick line, plus many additional operations due to theflexiblity of its up, down and rotational operation, without requiring the assistance of some type of surface mechanism. In essence, the workover and completion operations can be performed while downhole.
The present apparatus 30 may also be used to perform stimulation work while preventing highly toxic and corrosive fluids from coming in contact at undesired locations with the well conduit That is, fluids such as hydrofluoricor hydrochloric acid can be pumped down one of the control linesthrough the apparatus 30 and intothe formation 20 and prevented from flowing up the conduit 18 bythe sealing element 56 when actuated.
While the present invention has been described in connection with the control I i lines and multiple line bundle 34 as being hydraulic lines, these lines could instead be electrical lines operating electrical components to provide the desired work performing functions in a subsurface well.
White various kinds of propulsion units 32 may be usecifor moving the control line bundle 34 and the workproducing apparatus 30 along the inside of well conduits, one type of unit 32 is best seen inuFig.2. The.
unit 32 includes a body 90 supportingfirst!B2 and second 94 slip means which coactwfth piston actuated wedge members 96 and 98, nespectiveiì First 100 and second 102 springs acttaforce'tltesps 92 and 94 onto the wedge surfaces memhers 96 and 98, respectively. Actuation of piston members 96 and 98 is provided by hydraulic control lines 104 and 106, respectively. Thus, kydrauliefluid from line 104will move piston member96 forwardly and the spring 106 willfollowwiththe slip 92. Release of the fluid pressure in 104 andthe application of hydraulic pressure in 106 will acton the second end of the piston 96 to hold it in place while pressure is applied to the
piston member98to move is forward and allowthe spring 102to move the slips 94 onto the wedge
surface ofthe member 98 carrying the body 90 forwardly. Fluid pressure is then released in line 106 and again applied to line 104 to continue the movement. To reverse the direction ofthe propulsion unit 32 requires a duplicate mechanism operating in the opposite direction. The described propulsion unit 32 will move in steps and will have a positive gripping action and will be able to move large loads. However, othertypesof propulsion units such as hydraulically operated wheels or pumpdown may be used.
