Description
METHOD pli iifim FOR CLSANIIS THE IpFiR LOFTT® OF A WELL
The invention relates to a method for cleaning the upperportion of a well::. More particularly it> relates to a methodfor removing scale from the upper portion of a well, whereina tool with rotatable cleaning head is coupled co a wirelineand is moved, into the -$@£11,* The rnvenfcion also comprises: adevice for carrying out the method.
Scale in pnhniars: and wells in connection with petroleumattraction may entail considerable obstacles related to production, and function,.
Scale has a tendency to form particularly at flowconstrictions and in the upper portion of a well. It is tr,usa problem that scale for instance in a downhole safety Valvemay prevent such a valve from being operated as -wanted.
It is hno«: to use rotating tools on ;a so-called wireline-tractor to loosen scale in tubulars and other equipment.
Equipment of this kind has the severe weakness that a part ofavailable electric power which can be supplied via arelatively long and thin:wire is used for driving thewireline-tractor. Thus there is relatively little power leftto drive- the rotatable cleaning head.
relates to a tæthed tier cleaning of a: tubularbody in the ground. More particularly, it concerns a method for cleaning a tubular body in the ground, wherein a cablemachine .located in the tubular body is provideo virith acleaning tool# the cable machine being connected to a cablecomprising an electric conductor# and ihe cable extendingbetween the cable machine and surfadd. The invention alsocomprises a .device for carrying out the method.
U320050217S67 relates to apparatus and metnods for removingsand and/or other fill material located in a wellbore aheadof a coiled tubing tractor and displacing the material behindthe tractor. More particularly, the apparatus and methods ofthe present invention allow a coiled tubing tractor to driveforward in a wellbore by the removal of fill material ih,front of the tractor thereby allowing the wheels or traction,pads of the tractor to remain in contact with the wellbore.
WOO131160 discloses a method of carrying out operationa; inunderground/subsea oil/gas wells# preferably by theutiMaatåbb: of' coiled tubing to carry the work tool. Morespecifically, this method is: meant to be used for advancing arotating downhole tool in an underwater' well, wherein saidtool is brought to rotate by means of a downhole motorcarried by the coiled tubing.
WG2G10123375 discloses a straker for use in a borehole in theground. The stroter comprises an actuator arranged for beingable to displace a tool in the longitudinal direction of theborehole, and grippers anumged to anchor the stroke® to thewall of the borehole, alternatively to a pipe wall.
The ihvéntidh has for its object to .remedy or reduce at leastone of the drawbacks of the prior art..
The object is achieved through features which are specifiedin the descriptio®: Éelow and in the claims that follow.
There £g provided a method for removing scale front the upperportion of a well, wherein a tool with, a rotatable cleaninghead is coupled to a wireline, and is moved into the well, andidildh method is char act e r i zed by comprising; — providing a roller anchor with a motor for driving therotatable cleaning head! ;* coupling the rotatable cleaning head to the motor; - letting ffe# tool· :he:· ;Obv©d infor the wll fey ifes: pwn: weight..
3y omitting the wiraline-tractor and relying on moving thetool into the -well by means of its own weight, nearly all thepower which can be supplied via the wireline may be used fcpiårlve the- rbtstahiei bleanlhf; ;liead...
Another advantage is that there is no need to consider awireline of the same length as: Wfeem relying on:tfeevusevoi awire line -1 r ac tor, A wireline with can thereby be used, which enables transmission of more electric power,,:; 'The method may comprise providing the roller :ahcfec«r with ahydraulic aggregate in order to be able to move the wheels ofthe roller anchor towards the well. A pump of the hydraulicaggregate may with aivantage be coupled feo: :¾¾ jBOtor in auoha way that the wheels of the roller anchor is forced towardsthe wall of the well when the motor is started for drivingthe rotatable teal.
Control from the surface Is thereby limited to simple startand stop of the tool, and feeding and extracting wireline inthe: well >
The jcthod may be carried out by means of a cleaningequipment for removing scale from the upper portion of aWeil, wherein a tool with, rotatable cleaning head is coupledto a Wireline: and is movable into the well, and wherein; the tool is formed by a roller anchor with driving motor for therotatable cleaning head and a hydraulic aggregate fdfactuating the wheels of the roller anchor cowards the well.
The wireline may be coupled to thee roller anchor· by; meads; ,oia cable head and a, swivel.
The hydraulic aggregate may be driven by the motor andprovided with an accumulator.
.The 'rotating tool -may: be formed, by a drill "bit,, wt has beenshown that a drill bit is considerably more efficient forremoving scale than traditional roller cones, -which arearranged to roll against the., Scale, 'This is particularly thecase when more electric power is available compared to whenmaCng wireline-tractors.
The method and the device addordihg to the invention enable aconsiderably more efficient scale-removal compared to priorart.
In what follows:, an example of a preferred method and,embodiment is described, which is visualized in theaccompanying drawing, in which; iFigure 1 illustrates a tool according to the invention.
In the drawing the reference numeral 1 designates a tool forthe removal of scale 2 from the upper portion, of a well i.
The tool 1 comprises a roller anchor 6 which is provided, witha motor 3 for driving a .rotatable cleaning head IS,preferably formed by a drill bit. The rotatable cleaning head10 is supported in a bearing unit 12.
The roller anchor € is coupled to a wireline lå by means of a©able head IS and swivel 18 of a type known per se.
“IfM ;;r<a|ier anchor 6 is further provided with' a hydraulic 20 which is arranged bo ida able to move the wheeii22 of the roller anchor 6 out. towards the well 4. The, notillustrated, pump of the hydraulic aggregate 20 is driven bythe motor s >:
The tool 1 is moved into the well by means of its own weightby paying out wireline 14. When the cleaning operation Isabout; to start, voltage is coupled to the wireline 14,whereby the motor 8 starts and the rotatable cleaning head IDis: caused to pivot relative to the roller anchor 5.
the same time the motor s drives the ndt illustr&tei tp^$iof the hydraulic aggregate 2C; causing the wheels 22 to bemoved towards the: pell 4 and preventing the rqller anchor €from pivoting in the well 4.
A roller anchor 6 of this kind is able to take up aconsiderable torque, while at the same time it can easily berolled bach and forth in the: well 4. Thus, it is possible tocontrol the feeding rate relative to the measured powerconsumption, which is mainly used for driving the rotatablecleaning heed 10. There is thereby achieved an efficientcleaning at the same time as the risk for getting stuck isconsiderably reduced.
