Description
Patentbeskrivelse: Patent description:
System for håndtering av brønnintervensjonsutstyr i tilknytning til brønn. System for handling well intervention equipment in connection with a well.
Denne oppfinnelse vedrører et system for sikker håndtering av brønnintervensjonsutstyr som rigges på toppen av brønn innenfor petroleumsvirksomhet. This invention relates to a system for the safe handling of well intervention equipment that is rigged on top of a well within petroleum operations.
Brønnintervensjonsoperasjoner har vært vanlig i flere år, og det har i den senere tid blitt økt fokus på sikre og effektive løsninger. Ved brønnintervensjonsoperasjoner er det vanlig å kjøre verktøy ned i trykksatte brønner for å måle eller pleie brønnen. Eksempler på pleie, kan være utvasking av sedimenter, oppsplitting av formasjon og syrevasking av avleiringer. Alt dette for å øke produksjonsrate og få økt utvinningsgrad fra brønnen. Well intervention operations have been common for several years, and there has recently been an increased focus on safe and effective solutions. During well intervention operations, it is common to drive tools down into pressurized wells to measure or maintain the well. Examples of care can be washing out sediments, splitting up formations and acid washing of deposits. All this to increase the production rate and increase the recovery rate from the well.
I hovedsak er det to metoder for brønnintervensjon, kabeloperasjoner og kveilerør. Kabeloperasjoner går i hovedsak ut på å fire ned et nedihulls-verktøy med en ståltråd, vaier eller komposittstang, mens kveilerøroperasjoner gir mulighet til å pumpe væske. Kveilerørsoperasjoner krever en mateinretning (1) for å overvinne kreftene som oppstår som følge av trykkdifferansen. Operasjonene utføres ved at flere nedihullsverktøy kjøres inn og ut av brønn, og det er derfor behov for å frakoble en øvre del av trykk-kontrollsutstyret samt mateinreting, løfte det av og sideforskyve for å komme til ved verktøyhåndtering til/fra brønn. Ettersom nevnte brønnkontrollsutstyr varierer i størrelser og oppriggingshøyder, er det ønskelig med et system som gir fleksibilitet og mulighet til å justere arbeidsnivå i forhold til opprigging i tillegg til håndtering av brønnkontrollsutstyr og mateutstyr. There are essentially two methods of well intervention, cable operations and coiled tubing. Cable operations essentially consist of drilling down a downhole tool with a steel wire, cable or composite rod, while coiled tubing operations provide the opportunity to pump fluid. Coiled tube operations require a feed device (1) to overcome the forces arising from the pressure differential. The operations are carried out by driving several downhole tools into and out of the well, and there is therefore a need to disconnect an upper part of the pressure control equipment as well as the feed device, lift it off and move it sideways to get to it when handling tools to/from the well. As the aforementioned well control equipment varies in size and rigging heights, it is desirable to have a system that provides flexibility and the opportunity to adjust the work level in relation to rigging in addition to handling well control equipment and feeding equipment.
Det finnes allerede utstyr som kan løfte av og kjøre til siden, men med begrenset fleksibilitet med tanke på tilpassing av høyder på arbeidsdekk i forhold til oppriggingen. Løsningen beskrevet i patent NO 314361 er et eksempel på dette. Utstyret beskrevet i NO 314361 er i hovedsak tilrettelagt for å kunne håndtere kveilerørsmater (1) med tilhørende trykk-kontrollutstyr tilsvarende, men har ikke den samme fleksibilitet for varierende opprigginger. Dette som følge at løsningen beskrevet i patent NO 314361 har roterende skruer. Patent NO 314361 beskriver heller ikke de tilleggsfunksjoner for håndtering av nedihullsverktøy og inntrekking av kveilerør fra kveilerørstrommel. There is already equipment that can lift off and drive to the side, but with limited flexibility in terms of adjusting the height of the working deck in relation to the rigging. The solution described in patent NO 314361 is an example of this. The equipment described in NO 314361 is mainly designed to be able to handle coiled pipe feeders (1) with corresponding pressure control equipment, but does not have the same flexibility for varying set-ups. This is because the solution described in patent NO 314361 has rotating screws. Patent NO 314361 also does not describe the additional functions for handling downhole tools and retracting the coiled pipe from the coiled pipe drum.
Oppfinnelsen har til formål å optimalisere arbeidsforhold, og samtidig sørge for sikker håndtering ved de beskrevne brønnkontroll og mateinnretninger. The purpose of the invention is to optimize working conditions, and at the same time ensure safe handling of the well control and feeding devices described.
Formålet oppnås i henhold til oppfinnelsen ved de trekk som er angitt i nedenstående beskrivelse og i de etterfølgende patentkrav. The purpose is achieved according to the invention by the features indicated in the description below and in the subsequent patent claims.
En stasjonær bunnramme (2) med en eller flere føringssøyler (3) og en eller flere hev- og senkbare rammer eller plattformer (4). Rammen for løft av brønnkontroll- og mate- utstyr (5), er og forsynt med et horisontalt forskyvbart bord (6), som også kan dreies og har system for heving og senkning av to eller flere hjørner (7). Med dette oppnås muligheten for følgende bevegelser under håndtering av nevnte brønnkontrollutstyr og mateinnretning: løft, horisontal forskyving, dreiing og vipping om to akser. Øvrige rammer og plattformer er normalt bare hev- senkbare, men kan ha annen funksjonalitet i tillegg som for eksempel sideforskyving. A stationary bottom frame (2) with one or more guide columns (3) and one or more raiseable and lowerable frames or platforms (4). The frame for lifting well control and feeding equipment (5) is also equipped with a horizontally movable table (6), which can also be rotated and has a system for raising and lowering two or more corners (7). With this, the possibility of the following movements is achieved during handling of the aforementioned well control equipment and feeding device: lifting, horizontal displacement, turning and tilting about two axes. Other frames and platforms are normally only adjustable, but may have other functionality in addition, such as lateral displacement.
Hev- senke bevegelsen kan kjøres individuelt for de forskjellige rammene/plattformene (4), da hver ramme/plattform er utstyrt med synkronisert jekkesystem som hver for seg opererer på stillestående skruer. Til drift kan en enkelt eller flere synkroniserte motorer benyttes. Synkronisering kan være mekanisk eller i form av måling og styring. Forskyving i horisontalplan og vipping kan arrangeres på flere måter, som for eksempel ved hjelp av hydrauliske sylindere eller skrusystem. Rotasjon kan være manuell ved hjelp av temporært tilknyttet talje, eller ved permanent mekanisk drivsystem. Alle funksjoner kan være hydraulisk eller elektrisk opererte. The lifting-lowering movement can be driven individually for the different frames/platforms (4), as each frame/platform is equipped with a synchronized jacking system that operates separately on stationary screws. For operation, a single or several synchronized motors can be used. Synchronization can be mechanical or in the form of measurement and control. Displacement in the horizontal plane and tilting can be arranged in several ways, such as using hydraulic cylinders or a screw system. Rotation can be manual using a temporarily connected hoist, or by a permanent mechanical drive system. All functions can be hydraulically or electrically operated.
For å forenkle håndtering, og kunne håndtere lengst mulig nedihullsverktøy segmenter, er rammen som håndterer brønnkontrolls- og mate- utstyret er åpen i brønnenden (10), dvs. motsatt ende av der brønnkontrolls- og mate- utstyr (1) plasseres for bytte av nedihullsverktøy. Også plattformene (4) kan ha åpninger, eventuelt med segmenter som temporært kan fjernes. To simplify handling, and to be able to handle the longest possible downhole tool segments, the frame that handles the well control and feeding equipment is open at the well end (10), i.e. the opposite end of where the well control and feeding equipment (1) is placed for replacement downhole tool. The platforms (4) can also have openings, possibly with segments that can be temporarily removed.
Systemet kan videre utrustes med et kransystem (8) i form av en svingbar kran-arm eller en sammenleggbar løfteramme, som forenkler inn og utlasting av nedihullsverktøy komponenter. The system can also be equipped with a crane system (8) in the form of a swiveling crane arm or a collapsible lifting frame, which simplifies loading and unloading of downhole tool components.
For å forenkle håndteringen, spesielt når kveilerørstreng skal trekkes fra trommel til mateutstyr, kan rammen utrustet med en vinsj med kobling til kveilerør (9). Denne vinsjen har ikke brems og er arrangert slik at den mater ut når kraften overstiger en forhåndsdefinert verdi. To simplify handling, especially when the coiled pipe string is to be pulled from the drum to the feeding equipment, the frame can be equipped with a winch with a connection to the coiled pipe (9). This winch does not have a brake and is arranged so that it feeds out when the force exceeds a predefined value.
Styringen kan være direkte styrt, vha for eksempel hydrauliske ventiler eller strøm brytere, eller ved hjelp av et elektronisk kontroll system. Et elektronisk kontroll system kan ha radio forbindelse til brukerens kontroll panel. The control can be directly controlled, using, for example, hydraulic valves or power switches, or using an electronic control system. An electronic control system can have a radio connection to the user's control panel.
