ROTATIONSINDRETNING TIL MEKANISK ROTATIONSORIENTERING AF EN WIRELINETRAKTORROTATION FOR MECHANICAL ROTATION ORIENTATION OF A WIRELINET TRACTOR
Opfindelsen angår en indretning med en wirelinetraktor og en 5 rotationsindretning til mekanisk rotationsorientering af en wirelinetraktor i forhold til en sidelomme i et rør. Wirelinetraktoren, som er forsynet med hjul, som er forspændt mod rørets væg, og er forsynet med en finger, som under forspænding hviler mod rørets væg, og er bevægelig ind i en sidelomme, og er indrettet til under bevægelsen af wirelinetraktoren at følge 10 kantpartiet af sidelommen hvorved wirelinetraktorens hjul roteres til en rotationsstilling, i hvilken wirelinetraktorens hjul rotationsmæssigt befinder sig på siden af sidelommen.The invention relates to a device with a wireline tractor and a rotation device for mechanical rotation orientation of a wireline tractor relative to a side pocket of a pipe. The wireline tractor, which is provided with wheels which are biased against the wall of the pipe, and is provided with a finger which, under bias, rests against the wall of the pipe, and is movable into a side pocket, and is adapted to follow the edge portion during the movement of the wireline tractor. of the side pocket, whereby the wheels of the wireline tractor are rotated to a rotational position in which the wheels of the wireline tractor are rotationally on the side of the side pocket.
US 4640350 A beskriver et kendt værktøj af denne art til brug i et brøndrør, 15 hvor værktøjet skal orienteres i forhold til en lomme i brønden. Værktøjet styres på plads ved hjælp af en finger, der styres på plads i en rille i brøndrøret, hvorved værktøjet indtager en korrekt vinkelposition.US 4640350 A discloses a known tool of this kind for use in a well pipe, wherein the tool is to be oriented relative to a pocket in the well. The tool is controlled in place by means of a finger which is guided in place in a groove in the well pipe, whereby the tool occupies a correct angular position.
I forbindelse med installations- og vedligeholdelsesarbejde i et rør, typisk i 20 et rør i tilknytning til udvinding af jordolie, hvor der anvendes en såkaldt wirelinetraktor, er det velkendt, at wirelinetraktoren kan sætte sig fast i såkaldte sidelommer i røret.In connection with installation and maintenance work in a pipe, typically in a pipe in connection with the extraction of petroleum, using a so-called wireline tractor, it is well known that the wireline tractor can get stuck in so-called side pockets in the pipe.
Sidelommer af denne art kan være anordnet for at rumme for eksempel 25 måleudstyr, ventiler eller andet hjælpeudstyr, som letter driften af installationen.Side pockets of this kind may be provided to accommodate, for example, 25 measuring equipment, valves or other auxiliary equipment which facilitates the operation of the installation.
Når et af hjulene på wirelinetraktoren, som er forspændt mod rørvæggen, ruller ind i en sidelomme, hænder det forholdsvis ofte, at wirelinetraktoren 30 ikke kommer længere ind i røret ved sin egen kraft. Det er således ofte nødvendigt at trække wirelinetraktoren et stykke tilbage ved hjælp af for 2 DK 177384 B1 eksempel et kabel til jordoverfladen for at få det løs igen.When one of the wheels of the wireline tractor, which is biased against the pipe wall, rolls into a side pocket, it relatively often happens that the wireline tractor 30 no longer enters the pipe by its own power. Thus, it is often necessary to retract the wireline tractor some distance by means of, for example, a cable to the ground surface to get it loose again.
Derefter skal der gøres et nyt forsøg på køre wirelinetraktoren forbi sidelommen. Det er normalt, at dette kun lykkes efter adskillige forsøg, eftersom 5 kendte wirelinetraktorer ikke er forsynet med organer til at styre fri af sidelommer.Then try again to run the wireline tractor past the side pocket. It is normal for this to succeed only after several attempts, since 5 known wireline tractors are not provided with means to steer clear of side pockets.
Opfindelsen har som formål at afhjælpe eller reducere i det mindste en af ulemperne ved den kendte teknik.The invention has for its object to alleviate or reduce at least one of the disadvantages of the prior art.
1010
Formålet opnås ifølge opfindelsen ved de træk, der er angivet i den følgende beskrivelse og i kravene, der følger.According to the invention, the object is achieved by the features set forth in the following description and in the claims which follow.
Ifølge opfindelsen udføres den mekaniske rotationsorientering af en 15 wirelinetraktor i forhold til en sidelomme i et rør, med en indretning med en wirelinetraktor og en rotationsindretningen ifølge krav 1, som er kendetegnet ved, at fingeren er forbundet med et legeme, som med en løsbar forbindelse mellem legemet og rotationsindretningens dorne som tillader at legemet er roterbart omkring længdeaksen af wirelinetraktoren, 20 når den løsbare forbindelse er løsnet, for indstilling af en ønsket vinkel imellem fingeren og wirelinetraktorens hjul. Herved opnås, at wirelinetraktoren kan trækkes bagud inde i røret, hvis et hjul ruller ind i en sidelomme, idet en finger, som er forbundet med wirelinetraktoren, og som under forspænding hviler mod rørets væg, bringes til at trænge ind i 25 sidelommen, idet fingeren under fortsat tilbagetrækning af wirelinetraktoren følger sidelommens kantparti, hvorved wirelinetraktorens hjul roteres omkring wirelinetraktorens længdeakse, indtil wirelinetraktorens hjul rotationsmæssigt befinder sig på siden af sidelommen.According to the invention, the mechanical rotation orientation of a wireline tractor relative to a side pocket of a tube is carried out, with a device with a wireline tractor and the rotation device according to claim 1, characterized in that the finger is connected to a body which has a detachable connection. between the body and the mandrel of the rotary device which allows the body to be rotatable about the longitudinal axis of the wireline tractor, when the detachable connection is loosened, to adjust a desired angle between the finger and the wheels of the wireline tractor. Hereby, the wireline tractor can be pulled backwards within the tube if a wheel rolls into a side pocket, a finger connected to the wireline tractor resting on the wall of the tube under bias causing it to penetrate the side pocket, the finger during continued retraction of the wireline tractor follows the edge portion of the side pocket, whereby the wheels of the wireline tractor are rotated about the longitudinal axis of the wireline tractor until the wheels of the wireline tractor are rotationally on the side of the side pocket.
30 Wirelinetraktoren kan derpå køres længere ind i røret, eller den kan trækkes tilbage, indtil trækkraften overvinder kraften fra en støttefjeder, hvorved 3 DK 177384 B1 fingeren glider ud af sidelommen.The wireline tractor can then be driven further into the pipe, or it can be withdrawn until the traction overcomes the force of a support spring, whereby the finger slides out of the side pocket.
Fingeren, der under forspænding hviler mod sidevæggen og er bevægelig ind i en sidelomme, ertypisk drejeligt forbundet med wirelinetraktoren. Efter 5 at fingeren er drejet ind i sidelommen, vil den komme til at hvile på kantpartiet af sidelommen og blive bevæget langs dette under den yderligere bevægelse af wirelinetraktoren i røret. Ved at fingeren følger kantpartiet af sidelommen, roteres wirelinetraktoren eller nærmere bestemt wirelinetrakto-rens hjul omkring længdeaksen af wirelinetraktoren.The finger, which under bias, rests against the side wall and is movable into a side pocket, typically pivotally connected to the wireline tractor. After the finger is rotated into the side pocket, it will rest on the edge portion of the side pocket and be moved along it during the further movement of the wireline tractor in the tube. As the finger follows the edge portion of the side pocket, the wireline tractor or more specifically the wheels of the wireline tractor are rotated about the longitudinal axis of the wireline tractor.
1010
Sidelommer af denne art er ofte aflange i retning af røret og tilvejebringer derfor en passende indstyring af fingeren mod et centreret punkt, der, når rotationen er afsluttet, er centreret mellem hjulene.Side pockets of this kind are often elongated in the direction of the tube and therefore provide an appropriate guide of the finger towards a centered point which, when the rotation is completed, is centered between the wheels.
15 Fingeren er drejelig mellem en inddrejet inaktiv stilling og en uddrejet aktiv stilling og er forspændt mod rørets væg med en forholdsvis lille kraft.The finger is rotatable between a retracted inactive position and a extended active position and is biased against the tube wall with a relatively small force.
Endvidere er fingeren forspændt med en forholdsvis stor kraft i en hovedsagelig aksial bagudgående retning. Fingerens støtte er givet en udform-20 ning, der bevirker, at fingeren, hvis denne forspændingskraft overvindes, bevæges til en inddrejet inaktiv stilling.Furthermore, the finger is biased with a relatively large force in a substantially axial backward direction. The finger support is provided with a design which causes the finger, if this biasing force is overcome, to move to a retracted idle position.
For at indstille fingerens position i forhold til wirelinetraktorens hjul er fingeren forbundet med et legeme, der er rotationsmæssigt justerbart i forhold til 25 wirelinetraktorens længdeakse. Fingerens vinkel i forhold til hjulene kan derved justeres til opnåelse af den tilsigtede virkning.To adjust the position of the finger relative to the wheels of the wireline tractor, the finger is connected to a body which is rotationally adjustable relative to the longitudinal axis of the wireline tractor. The angle of the finger relative to the wheels can thereby be adjusted to achieve the intended effect.
Rotationsindretningen ifølge opfindelsen giver ved deres enkle konstruktion og virkemåde en betydeligt forbedret rotationsstyring af en wirelinetraktor, 30 hvilket i betydelig grad vil kunne effektivisere arbejde af denne art.The rotary device according to the invention gives, by their simple construction and operation, a significantly improved rotary control of a wireline tractor, which can considerably improve efficiency of this kind of work.
4 DK 177384 B1 I det følgende beskrives der et ikke-begrænsende eksempel på en foretrukket udførelsesform, som er anskueliggjort på de medfølgende tegninger, hvor: 5 Figur 1 viser et længdesnit gennem et rør og en rotationsindretning; figur 2 viser et snit la-la af figur 1; figur 3 viser en afbildning Ib-lb af figur 1; 10 figur 4 viser det samme som figur 1, men efter at fingeren er blevet bevæget ind i sidelommen; og figur 5 viser det samme som figur 4, men her er fingeren ved at blive be-15 væget til sin inaktive inddrejede stilling.4 DK 177384 B1 The following describes a non-limiting example of a preferred embodiment, which is illustrated in the accompanying drawings, in which: Figure 1 shows a longitudinal section through a pipe and a rotary device; Figure 2 shows a section la-la of Figure 1; Figure 3 shows a view Ib-1b of Figure 1; Figure 4 shows the same as Figure 1, but after the finger has been moved into the side pocket; and Figure 5 shows the same as Figure 4, but here the finger is being moved to its inactive retracted position.
På tegningerne angiver henvisningstallet 1 en rotationsindretning, der er forbundet med forpartiet af en wirelinetraktor 2. Foran rotationsindretningen kan der være anbragt et værktøj 5. Et aggregat af wirelinetraktoren 2 og 20 rotationsindretningen 1 er bevægeligt i et rør 4.In the drawings, reference numeral 1 indicates a rotation device connected to the front portion of a wireline tractor 2. A tool 5 may be arranged in front of the rotation device. An assembly of the wireline tractor 2 and 20 the rotation device 1 is movable in a pipe 4.
1 røret 5 er der anordnet en sidelomme 6, der på tegningerne er illustreret som en gennemgående åbning i væggen af røret 4. Sidelommen 6 er normalt udformet som en noget langstrakt åbning, der fortrinsvis går over i et 25 slidsformet parti 8 ved sin del, der vender mod jordoverfladen.In the tube 5 there is provided a side pocket 6, which is illustrated in the drawings as a through opening in the wall of the tube 4. The side pocket 6 is usually formed as a somewhat elongated opening, which preferably extends into a slotted portion 8 at its part, facing the soil surface.
En wirelinetraktor 2 indbefatter hjul 10, se figur 2, der er fordelt om wirelinetraktoren på en i og for sig kendt måde. I det mindste nogle af hjulene 10 er drevet, og alle er forspændt ud mod den indre væg af røret 4 for ved 30 hjælp af friktion at køre wirelinetraktoren 2 langs røret 4. En wirelinetraktor 2 kendes af en fagmand på området og beskrives derfor ikke nærmere.A wireline tractor 2 includes wheels 10, see Figure 2, which is distributed about the wireline tractor in a manner known per se. At least some of the wheels 10 are driven and all are biased against the inner wall of the tube 4 for frictionally driving the wireline tractor 2 along the tube 4. A wireline tractor 2 is known to one of ordinary skill in the art and is therefore not further described. .
5 DK 177384 B15 DK 177384 B1
Rotationsindretningen 1 indbefatter en første centerdorn 12 og en anden centerdorn 14, der er forbundet med den første centerdorn 12. Centerdornene 12 og 14 er forsynet med en centerboring 16, der strækker sig der-5 igennem, og er udformet med endeflanger 18, der komplementært passer med wirelinetraktoren 2.The rotary device 1 includes a first center mandrel 12 and a second center mandrel 14 connected to the first center mandrel 12. The center mandrels 12 and 14 are provided with a center bore 16 extending therethrough and are provided with end flanges 18 which complement fits with the wireline tractor 2.
Et legeme 20 i form af et fingerhus omgiver rotationsmæssigt centerdornene 12 og 14, idet den relative stilling af fingerhuset 20 i forhold til centerdornen 12, 14 kan fikseres ved hjælp af låseskruer 22.A body 20 in the form of a finger housing rotates circumferentially around the center mandrels 12 and 14, the relative position of the finger housing 20 relative to the center mandrel 12, 14 being fixed by locking screws 22.

Fingerhuset 20 er forsynet med mindst en udsparing 24, i hvilken en forholdsvis langstrakt finger 26 er støttet i en aflang slids 28 om en aksel 30. Akslen 30, der er vinkelret på længdeaksen af rotationsindretningen 1, ligger inde i udsparingen 24. Fingeren 26 er derved både rotationsmæssigt og 15 aksialt bevægelig omkring akslen 30.The finger housing 20 is provided with at least one recess 24 in which a relatively elongated finger 26 is supported in an elongate slot 28 about a shaft 30. The shaft 30 perpendicular to the longitudinal axis of the rotary device 1 lies within the recess 24. The finger 26 is thereby both rotationally and axially movable about the shaft 30.
I sin foretrukne udførelsesform er fingeren 26 forskudt udad mod røret 4 ved hjælp af en bladfjeder 32. Andre løsninger, såsom magnetiske eller elektrisk styrede, ikke viste aktuatorer, kan også være relevante til eventu-20 elt at bevæge fingeren 26 mod røret 4.In its preferred embodiment, the finger 26 is displaced outwardly against the tube 4 by a leaf spring 32. Other solutions, such as magnetic or electrically controlled actuators not shown, may also be relevant for possibly moving the finger 26 towards the tube 4.
Når fingeren 26 er i sin uddrejede aktive stilling, se figur 4, hviler den på et dæksel 34.When the finger 26 is in its extended active position, see Figure 4, it rests on a cover 34.
25 En trykfjeder 36 er anbragt forspændt i en boring 38 i dækslet 34 og spænder mellem udsparingen 24 af fingerhuset 20 og endepartiet af fingeren 26, der strækker sig indad, hvor trykfjederen 36 er ført over et styr 40.A compression spring 36 is biased into a bore 38 in the cover 34 and spans between the recess 24 of the finger housing 20 and the end portion of the finger 26 extending inwardly, the compression spring 36 being passed over a guide 40.
Hvis fingeren 26 bevæges i retning af trykfjederen 36 langs slidsen 28, 30 kommer en affasning 42 til at hvile på dækslet 34, se figur 5, hvorved fingeren 26 drejes til sin inddrejede inaktive stilling.If the finger 26 is moved in the direction of the compression spring 36 along the slot 28, 30, a bevel 42 will rest on the cover 34, see Figure 5, whereby the finger 26 is rotated to its retracted inactive position.
6 DK 177384 B1 Når wirelinetraktoren 2 sammen med rotationsindretningen 1 bevæges ind langs røret 4, kan fingeren 26 dreje ind i en sidelomme 6, mens den passerer sidelommen 6, se figur 4. På grund af en forholdsvis lille kraft fra blad-5 fjederen 32 vil fingeren 26 imidlertid dreje ud af sidelommen 6 ved passage af denne.6 DK 177384 B1 When the wireline tractor 2, together with the rotating device 1, moves along the pipe 4, the finger 26 can rotate into a side pocket 6 while passing the side pocket 6, see Figure 4. Due to a relatively small force from the leaf spring 32 however, the finger 26 will rotate out of the side pocket 6 upon passing it.
Skulle et af hjulene 10 af wirelinetraktoren rulle ind i sidelommen 6 og wirelinetraktoren 2 derved blive forhindret i at bevæge sig videre i røret 4, kan wirelinetraktoren 2 under sin egen kraft eller ved hjælp af anden kraft, for 10 eksempel via et ikke vist kabel til overfladen, blive bevæget bagud i røret 4.If one of the wheels 10 of the wireline tractor rolls into the side pocket 6 and the wireline tractor 2 is thereby prevented from moving further in the tube 4, the wireline tractor 2 can under its own power or by other force, for example via a cable not shown. the surface, being moved backwards in the tube 4.
Fingeren 26 vil dreje ind i sidelommen 6, når fingerens stilling er sammenfaldende med sidelommen 6. Under den videre bevægelse af wirelinetraktoren 2 i røret 4 vil fingeren 26 komme til at hvile på kantpartiet af sidelom-15 men 6 og følge det ind mod det slidsformede parti 8. Fingeren 26 roterer herved wirelinetraktoren 2 til en rotationsstilling, i hvilken hjulene 10 ikke svarer til stillingen af sidelommen 6.The finger 26 will rotate into the side pocket 6 when the position of the finger coincides with the side pocket 6. During the further movement of the wireline tractor 2 in the tube 4, the finger 26 will rest on the edge portion of the side pocket 6 and follow it towards the slit-shaped portion 8. The finger 26 hereby rotates the wireline tractor 2 to a rotational position in which the wheels 10 do not correspond to the position of the side pocket 6.
Hvis wirelinetraktoren 2 bevæges yderligere tilbage, kommer fingeren 26 til 20 at hvile på enden af det slidsformede parti 8, se figur 5. Når kraften fra trykfjederen 36 er overvundet, bevæges fingeren 26 langs slidsen 28 på akslen 30. Affasningen 42 kommer til at hvile på dækslet 34, hvorved fingeren 26 drejes til dens inddrejede inaktive stilling. Derved kan wirelinetraktoren 2 frit bevæges yderligere tilbage i røret 4. Alternativt kan wirelinetraktoren 2 be-25 væges yderligere ind i røret 4, idet hjulene 10 nu er i en stilling, i hvilken de kan passere sidelommen 6 uden at rulle ind i den.If the wireline tractor 2 is moved further back, the finger 26 to 20 will rest on the end of the slotted portion 8, see Figure 5. When the force of the compression spring 36 is overcome, the finger 26 moves along the slot 28 on the shaft 30. The bevel 42 will rest on the cover 34, thereby turning the finger 26 to its retracted inactive position. Thereby, the wireline tractor 2 can be freely moved further back into the tube 4. Alternatively, the wireline tractor 2 can be moved further into the tube 4, the wheels 10 being now in a position in which they can pass the side pocket 6 without rolling into it.
