Bakgrunnen for oppfinnelsen The background of the invention
Oppfinnelsen dreier seg om en fremgangsmåte for å kjøle en flerfase-brønnstrøm. The invention relates to a method for cooling a multiphase well flow.
En slik fremgangsmåte er kjent fra OTC-artikkel 17399 «Subsea Gas Compression - Challenges and Solutions» presentert av R.Fantoft ved konferansen om oljeutvinning til havs som ble holdt i Houston, USA den 2.-5. mai 2005, og fra de internasjonale patentsøknadene WO30/033870, WO03/035335 og WO2005/026497. Such a procedure is known from OTC article 17399 "Subsea Gas Compression - Challenges and Solutions" presented by R.Fantoft at the conference on offshore oil extraction held in Houston, USA on 2-5 May 2005, and from the international patent applications WO30/033870, WO03/035335 and WO2005/026497.
Fremgangsmåten som er kjent fra WO2005/026497 innbefatter å: The method known from WO2005/026497 includes:
- overføre fierfasebrønnstrømmen gjennom et røropplegg for flerfase-brønnstrøm til en gass/væske-separator der den flerfasede brønnstrøm-blandingen separeres til en stort sett gassformig og en stort sett væskeformig - transfer the four-phase well flow through a pipeline for multi-phase well flow to a gas/liquid separator where the multi-phase well flow mixture is separated into a mostly gaseous and a mostly liquid

Det er ønskelig å kjøle gassen før komprimering for høyest mulig ytelse ved en gitt installert komprimeringskraft. It is desirable to cool the gas before compression for the highest possible performance at a given installed compression force.
Fra norsk patentsøknad NO 1997 4447 fremgår det en fremgangsmåte ved produksjon av en brønn hvor en brønnstrøm føres gjennom en kritisk varme-utsatt presskomponent og et anlegg for produksjon av en brønn. En sirkula-sjonspumpe benyttes for å ivareta sirkulasjon. En masse som er kaldere enn brønnstrømmen blandes inn i brønnstrømmen oppstrøms for den varmeutsatte presskomponenten. Norwegian patent application NO 1997 4447 discloses a method for the production of a well where a well flow is passed through a critical heat-exposed pressure component and a plant for the production of a well. A circulation pump is used to ensure circulation. A mass that is colder than the well stream is mixed into the well stream upstream of the heat-exposed pressure component.
Det er et mål med den foreliggende oppfinnelsen å tilby en forbedret fremgangsmåte for å kjøle en flerfaset brønnstrømblanding. It is an object of the present invention to provide an improved method for cooling a multiphase well stream mixture.
Sammendrag av oppfinnelsen Summary of the invention
Den foreliggende oppfinnelsen vedrører således et selvregulerende, undersjøisk system for kjøling av en flerfaset brønnstrøm fra en undersjøisk produksjonsbrønn. En flerfaseleder føres inn i en separator for separasjon av gass og væske. En væskesirkulasjonssleder forløper fra separatoren. Systemet omfatter videre en sjøvannskjølt varmeveksler. Væske sirkulasjonslederen forløper direkte inn i varmeveksleren og videre direkte inn i flerfaselederen oppstrøms for separatoren, slik at systemet utelukkende består av statisk utstyr. The present invention thus relates to a self-regulating, subsea system for cooling a multiphase well flow from a subsea production well. A multiphase conductor is fed into a separator for the separation of gas and liquid. A liquid circulation sled extends from the separator. The system also includes a seawater-cooled heat exchanger. The liquid circulation conductor runs directly into the heat exchanger and further directly into the multiphase conductor upstream of the separator, so that the system consists exclusively of static equipment.
I henhold til oppfinnelsen tilbys det videre en fremgangsmåte for å kjøle en flerfase-brønnstrøm, hvor fremgangsmåten innbefatter å kjøle en flerfase-brønnstrøm. Fremgangsmåten innbefatter å separere fierfasebrønnstrømmen i gassanrikede og væskeanrikede fraksjoner i en gass/væske-separator. Den væskeanrikede fraksjon føres direkte til en varmeveksler. Fremgangsmåten omfatter videre å: According to the invention, a method for cooling a multiphase well stream is also offered, where the method includes cooling a multiphase well stream. The method involves separating the four-phase well stream into gas-enriched and liquid-enriched fractions in a gas/liquid separator. The liquid-enriched fraction is fed directly to a heat exchanger. The procedure also includes:
kjøle den væskeanrikede fraksjonen i varmeveksleren, cool the liquid-enriched fraction in the heat exchanger,
føre den væskeanrikede fraksjon fra varmeveksleren direkte inn i flerfase feed the liquid-enriched fraction from the heat exchanger directly into the multiphase
brønnstrømmen, og the well stream, and
sprøyte den avkjølte væskeanrikede fraksjonen inn i brønnstrømmen igjen inject the cooled liquid-enriched fraction back into the well stream
oppstrøms for gass/væske-separatoren. upstream of the gas/liquid separator.
Gass/væske-separatoren og varmeveksleren kan være nedsenket i (sjø-)vann og varmeveksleren kan kjøles av sjøvannet i omgivelsene. The gas/liquid separator and the heat exchanger can be immersed in (sea) water and the heat exchanger can be cooled by the seawater in the surroundings.
Den drivende kraften for væskesirkulasjonen kan fås fra den statiske fallhøyden mellom væskenivået i separatoren og injeksjonspunktet. Spesielle fordeler med fremgangsmåten i henhold til oppfinnelsen er at eventuell gas som føres med væskestrømmen og væske som føres med gasstrømmen er neglisjerbar, noe som eliminerer behovet for nivåkontroll. Systemet kan derfor bestå utelukkende av statisk utstyr (dvs. at det ikke trenger pumpe, ingen strømtilførsel, ingen instrumentering og ingen kontroller) og derfor er ekstremt robust, tørrstoff-tolerant og har lavt utgiftsnivå. The driving force for the liquid circulation can be obtained from the static head between the liquid level in the separator and the injection point. Special advantages of the method according to the invention are that any gas carried with the liquid flow and liquid carried with the gas flow are negligible, which eliminates the need for level control. The system can therefore consist exclusively of static equipment (ie it does not need a pump, no power supply, no instrumentation and no controls) and is therefore extremely robust, solids-tolerant and has a low level of expenditure.
Eventuelt kan flerfastbrønnstrømmen transporteres fra en eller flere gass-og/eller råoljeproduksjonsbrønner til gass/væske-separatoren gjennom en flerfaseleder for brønnstrømtransport og den avkjølte væskeanrikede fraksjonen kan sprøytes inn i flerfaselederen for brønnstrømtransport igjen ved hjelp av en strålepumpe, der flerfasestrømmen vil være det drivende fluidet. Dette vil forårsake et mindre trykkfall i flerfasestrømmen. Optionally, the multi-solid well stream can be transported from one or more gas and/or crude oil production wells to the gas/liquid separator through a multi-phase well stream transport conductor and the cooled liquid-enriched fraction can be injected into the well stream transport multi-phase conductor again by means of a jet pump, where the multi-phase stream will be the driving force the fluid. This will cause a minor pressure drop in the multiphase flow.
Gass/væske-separatoren kan være en hybrid syklon- og gravitasjonsseparator som innbefatter et stort sett loddrett orientert rørformet separasjonskar med væskeutløp nær bunnen av karet og gassutløp nær toppen av karet og et stort sett tangentielt innløp for flerfasefluid som er koblet til flerfaselederen for brønnstrømtransport. The gas/liquid separator may be a hybrid cyclone and gravity separator that includes a generally vertically oriented tubular separation vessel with a liquid outlet near the bottom of the vessel and a gas outlet near the top of the vessel and a generally tangential inlet for multiphase fluid that is connected to the multiphase conduit for well stream transport.

Detaljert beskrivelse av foretrukne realiseringer av oppfinnelsen Detailed description of preferred embodiments of the invention
FIG.1 viser en undersjøisk produksjonsbrønn 1 for naturgass og/eller råoljesom den produserte fierfasebrønnstrømmen G+L transporteres fra til en gass/- væske-separator 2 gjennom et røropplegg for transport av flerfase-brønnstrøm 3, som kan befinne seg nær havbunnen 4. FIG.1 shows an undersea production well 1 for natural gas and/or crude oil from which the produced four-phase well flow G+L is transported to a gas/liquid separator 2 through a pipeline for transporting multi-phase well flow 3, which can be located near the seabed 4.
Gass/væske-separatoren 2 innbefatter et separasjonskar av gravitasjonstypen der en væskefraksjon L samler seg i bunnen av karet og slippes ut i en væske-resirkulasjons-leder 5 der det er plassert en varmeveksler 6 hvor den resirkulerte væsken kjøles, slik at denne resirkuleringslederen slipper resirkulert kald væske Lkaid inn i flerfaselederen for transport av brønnstrøm 3, og den resirkulerte kalde væsken Uaid kjøler hele fierfasebrønnstrømmen, også gassfraksjonen, og dermed danner en avkjølt flerfasebrønnstrøm (G+L)kj0it som gjennom et øvre utløp 7 slippes ut til gass/væske-separatoren 2. The gas/liquid separator 2 includes a separation vessel of the gravity type where a liquid fraction L collects at the bottom of the vessel and is released into a liquid recirculation conductor 5 where a heat exchanger 6 is placed where the recycled liquid is cooled, so that this recirculation conductor releases recycled cold liquid Lkaid into the multi-phase conductor for transporting well stream 3, and the recycled cold liquid Uaid cools the entire four-phase well stream, including the gas fraction, and thus forms a cooled multi-phase well stream (G+L) mass which is discharged through an upper outlet 7 to gas/liquid - the separator 2.
FIG. 2 viser en foretrukket realisering av en gass/væske-separator til bruk i fremgangsmåten i henhold til oppfinnelsen, der separatoren innbefatter et stort sett loddrett orientert kar 22 som tilføres en flerfaseblanding av brønnstrøm G+L gjennom en tangentiell innløpsleder 20 fra en flerfaseleder 23 for transport av brønnstrøm, som er koblet til en undersjøisk produksjonsbrønn 21 for gass-og/eller råolje. Den tangentielle innløpslederen 20 sikrer at gass og væske separeres i bulk. FIG. 2 shows a preferred realization of a gas/liquid separator for use in the method according to the invention, where the separator includes a largely vertically oriented vessel 22 which is supplied with a multiphase mixture of well stream G+L through a tangential inlet conductor 20 from a multiphase conductor 23 for transport of well flow, which is connected to an underwater production well 21 for gas and/or crude oil. The tangential inlet conductor 20 ensures that gas and liquid are separated in bulk.
I separasjonskaret 22 samler det seg en væskefraksjon L i bunnen av karet som slippes ut i en væskeresirkuleringsleder 25 der det er plassert en varmeveksler 26 hvor den resirkulerte væsken kjøles slik at resirkuleringslederen slipper resirkulert kald væske Lkaid ut i flerfaselederen 23 for transport av brønnstrøm, slik at den resirkulerte kalde væsken Lkaid kjøler hele fierfase-brønnstrømmen, også gassfraksjonen, og det dannes en avkjølt flerfase-brønnstrøm (G+L)kjøit som gjennom et øvre utløp 27 slippes ut til gass/væske-separatoren 22. In the separation vessel 22, a liquid fraction L collects at the bottom of the vessel which is released into a liquid recycling conductor 25 where a heat exchanger 26 is placed where the recycled liquid is cooled so that the recycling conductor releases recycled cold liquid Lkaid into the multiphase conductor 23 for transporting well flow, as that the recycled cold liquid Lkaid cools the entire four-phase well flow, including the gas fraction, and a cooled multi-phase well flow (G+L) is formed which is discharged through an upper outlet 27 to the gas/liquid separator 22.
Den kalde resirkulerte væsken Lkaid sprøytes inn i lederen 23 gjennom en strålepumpe 28, som gjør at fierfasebrønnstrømmen G+L suger den resirkulerte kalde væsken Lkaid inn i ledning 23, uten at det trengs noen resirkuleringspumpe og slik at den resirkulerte kalde væsken Lkaid blandes godt med fierfase-brønnstrømmen G+L og effektivt kjøler denne strømmen. The cold recycled liquid Lkaid is injected into the conductor 23 through a jet pump 28, which causes the four-phase well flow G+L to suck the recycled cold liquid Lkaid into line 23, without the need for any recycling pump and so that the recycled cold liquid Lkaid mixes well with the four-phase well stream G+L and effectively cools this stream.
En fordel med å resirkulere kald væske inn i lederen 23 i stedet for å plassere en sjøvannskjølt varmeveksler i lederen 23 selv, er at varmeveksleren 6, 26 i væske-resirkuleringslederen er en væske/væske-varmeveksler, som kan være omtrent en tidel så stor som den gass/væske-varmeveksleren man ville trengt for å kjøle den potensielt hovedsakelig gassformige brønnstrømmen G+L som strømmer gjennom transport-lederen for brønnstrøm 3, 23. En annen fordel er at fierfasebrønnstrømmen kan inneholde tørrstoff som kan medføre risiko for vesentlig erosjon på varmeveksleren over tid hvis den var plassert i lederen 23. Denne risikoen er betydelig redusert siden hastigheten i kjøleren 26 er forholds-vis lav og det kan ordnes slik at det meste av tørrstoffet direkte forlater separatoren 20 gjennom lederen 27 i stedet for at de resirkuleres til lederen 25. Det kan være ønskelig å kjøle fierfasebrønnstrømmen hvis strømmen separeres og/eller komprimeres nedstrøms for varmeveksleren 2, 22. Strømningskapasiteten for en gitt komprimeringsinnsugning og utslippstrykk er lavere. Derfor er fremgangsmåten i henhold til oppfinnelsen egnet for kjøling av en flerfasebrønnstrøm effektivt på et undersjøisk sted, med en kompakt væske/væske-varmeveksler 6, 26 og uten at det kreves ytterligere undersjøiske pumpeorgan og/eller strømningsregulerende organ. An advantage of recirculating cold liquid into the conduit 23 instead of placing a seawater cooled heat exchanger in the conduit 23 itself is that the heat exchanger 6, 26 in the liquid recirculation conduit is a liquid/liquid heat exchanger, which can be about one-tenth the size as the gas/liquid heat exchanger one would need to cool the potentially mainly gaseous well flow G+L that flows through the transport conductor for well flow 3, 23. Another advantage is that the four-phase well flow can contain dry matter which can entail a risk of significant erosion on the heat exchanger over time if it was located in the conductor 23. This risk is significantly reduced since the speed in the cooler 26 is relatively low and it can be arranged so that most of the dry matter directly leaves the separator 20 through the conductor 27 instead of being recycled to the conductor 25. It may be desirable to cool the four-phase well flow if the flow is separated and/or compressed downstream of the heat exchanger 2, 22. Flow capacity the site for a given compression intake and discharge pressure is lower. Therefore, the method according to the invention is suitable for cooling a multiphase well flow efficiently in a subsea location, with a compact liquid/liquid heat exchanger 6, 26 and without requiring additional subsea pumping means and/or flow regulating means.
