Abstract
For testing av en brønnstrøm blir en delmengde av brønnstrømmen avdelt, testet og ført tilbake til brønnstrømmen. Den avdelte delmengde separeres i en testseparator (13) hvis gassrom (14) er tilknyttet et gassrom (8) i en brønnstrømseparator (1), mens vaskerommet (16) er strømningstilknyttet væskerommet (9) i brønnstrømseparatoren, på en slik måte at nivået i teststrømseparatoren (16) i hovedsaken følger nivået i brønnstrømseparatoren. Testingen foretas ved at man tester de respektive gass/væskestrømmer fra test-separatoren (13) til brønnstrømseparatoren (1).For testing a well stream, a subset of the well stream is divided, tested and returned to the well stream. The divided subset is separated in a test separator (13) whose gas space (14) is connected to a gas space (8) in a well flow separator (1), while the washing space (16) is flow-connected to the liquid space (9) in the well flow separator, in such a way that the level in the test current separator (16) essentially follows the level in the well current separator. The testing is performed by testing the respective gas / liquid flows from the test separator (13) to the well flow separator (1).
Description
Oppfinnelsen vedrører et anlegg for testing av en brønn-strøm, særlig på havbunnen, innbefattende en brønnstrøm-ledning, en med brønnstrømledningen parallellkoplet test-strømledningskrets, en teststrømseparator i teststrøm-ledningskretsen, med en væskedel og en gassdel, og testutstyr for testing av de med teststrømseparatoren i den parallellkoplede teststrømledningskrets separerte gass- og væske-strømmer. The invention relates to a facility for testing a well current, particularly on the seabed, including a well current line, a test current line circuit connected in parallel with the well current line, a test current separator in the test current line circuit, with a liquid part and a gas part, and test equipment for testing the with the test current separator in the parallel-connected test current line circuit separated gas and liquid streams.
Når undervanns-produksjon foregår fra flere hydrokarbon-brønner, er det av stor interesse å kunne faststlå trykk, temperatur, gass- og væskeproduksjon og olje/vann-forhold fra hver brønn separat. When underwater production takes place from several hydrocarbon wells, it is of great interest to be able to determine pressure, temperature, gas and liquid production and oil/water ratio from each well separately.
For et felt der brønntrykket er tilstrekkelig, kan undervanns-systemet bygges slik at man kan føre strømmen fra en brønn gjennom et "test-manifold" og en egen rørledning opp til overflaten, mens resten av produksjonen føres gjennom hoved-manifolden og hoved-rørledningen. For a field where the well pressure is sufficient, the underwater system can be built so that the flow from a well can be led through a "test manifold" and a separate pipeline up to the surface, while the rest of the production is led through the main manifold and the main pipeline .
I noen felt vil brønntrykket ikke være tilstrekkelig til å drive produksjonen til overflaten med det trykk mottager-stasjonen forlanger. Det vil da være aktuelt å benytte en undervannsstasjon som innbefatter en undervanns-separator for brønnstrømmen, en pumpe og eventuelt en kompressor. In some fields, the well pressure will not be sufficient to drive production to the surface with the pressure receiver station demands. It will then be relevant to use an underwater station which includes an underwater separator for the well flow, a pump and possibly a compressor.
For å kunne teste en brønn i et felt med en slik undervannsstasjon, foreligger det i utgangspunktet to muligheter. In order to be able to test a well in a field with such an underwater station, there are basically two possibilities.
Man kan føre testproduksjonen til overflaten for måling. Siden trykket forutsettes å være utilstrekkelig betinger dette at det installeres et eget hjelpeanlegg dimensjonert for produksjonen fra en brønn. Dette hjelpeanlegg må innbefatte en separator og en pumpe, og ofte også en kompressor. The test production can be brought to the surface for measurement. Since the pressure is assumed to be insufficient, this requires the installation of a separate auxiliary plant dimensioned for production from a well. This auxiliary system must include a separator and a pump, and often also a compressor.
Den andre muligheten er å utføre målingene på havbunnen. Det finnes tilgjengelig instrumenter som kan måle de ønskede størrelsene etter at gass og væske er separert. The other possibility is to carry out the measurements on the seabed. There are instruments available that can measure the desired sizes after gas and liquid have been separated.
Foreliggende oppfinnelse vedrører et anlegg som muliggjør slik testing eller måling på havbunnen. The present invention relates to a facility which enables such testing or measurement on the seabed.
Fra et foredrag på Offshore Technology Conference 1990 i Houston, Texas, offentliggjort i trykt versjon som OTC 6426 med tittelen A New Microwave Based Water-cut Monitor Technology, av G.J. Hatton, D.A. HeLms, J.D. Marrelli og M.G. Durrett, Texaco Inc., er det kjent å teste eller måle en fra en brønnstrøm i en parallellkoplet teststrømledningskrets avdelt teststrøm. Man beskriver imidlertid bare måling av væskeandelen, og det beskrevne utstyr er slik at man bare kan foreta en avgrening fra et respektivt brønnstrømrør. From a talk at the 1990 Offshore Technology Conference in Houston, Texas, published in print as OTC 6426 entitled A New Microwave Based Water-cut Monitor Technology, by G.J. Hatton, D.A. Helms, J.D. Marrelli and M.G. Durrett, Texaco Inc., it is known to test or measure a from a well current in a parallel connected test current line circuit divided test current. However, only measurement of the liquid portion is described, and the equipment described is such that a branch can only be made from a respective well flow pipe.
Fra US-PS 4.951.700 er det kjent en fremgangsmåte og utstyr for å måle mengden av olje i brønner. En delmengde tas ut fra brønnstrømmen, testes og føres tilbake til brønnstrømmen. I testprosessen inngår det bruk av separator som deler strømmen opp i en blanding av gass og væske. From US-PS 4,951,700 a method and equipment for measuring the amount of oil in wells is known. A partial quantity is taken out of the well stream, tested and returned to the well stream. The test process includes the use of a separator that divides the flow into a mixture of gas and liquid.
Den spesielle hensikt med foreliggende oppfinnelse er å kunne muliggjøre en avgrening og testing av såvel væske- som gass-fasen fra en brønnstrømledning valgt blant flere brønnstrøm-ledninger. The particular purpose of the present invention is to be able to branch off and test both the liquid and gas phases from a well flow line selected from among several well flow lines.
En særlig hensikt med oppfinnelsen er også å muliggjøre testing av en brønnstrøm i et undervannsanlegg av den type som er vist og beskrevet i NO-søknad P890057 (US-Serial no. 07/460 398 filed 01/03/90). A particular purpose of the invention is also to enable testing of a well flow in an underwater installation of the type shown and described in NO application P890057 (US-Serial no. 07/460 398 filed 01/03/90).
Et slik undervannsanlegg innbefatter en brønnstrømseparator, hvor brønnstrømmen separeres i væske og gass, en pumpe for energitilførsel til den utseparerte væske og en kompressor for energitilførsel til den utseparerte gass. Such an underwater facility includes a well stream separator, where the well stream is separated into liquid and gas, a pump for supplying energy to the separated liquid and a compressor for supplying energy to the separated gas.
Ifølge oppfinnelsen foreslås det et anlegg for testing av en brønnstrøm særlig på havbunnen, innbefattende en brønnstrøm-ledning, en med brønnstrømledningen parallellkoplet test-strømledningskrets, en teststrømseparator i teststrømled-ningskretsen, med en væskedel og en gassdel, og testutstyr for testing av de med teststrømseparatoren i den parallellkoplede teststrømledningskrets separerte gass- og væske-strømmer, kjennetegnet ved at en brønnstrømseparator, som har en væskedel og en gassdel, er tilknyttet flere brønnstrømled-ninger som har avgreningsledninger som går til teststrøm-separatoren, at en væskeledning går fra teststrømseparatorens væskedel til brønnstrømseparatorens væskedel, og at en gassledning går fra teststrømseparatorens gassdel til brønn-strømgeneratorens gassdel, idet arrangementet er slik at nivået i teststrømseparatoren i hovedsaken følger nivået i brønnstrømseparatoren. According to the invention, a facility is proposed for testing a well stream, particularly on the seabed, including a well stream line, a test power line circuit connected in parallel with the well stream line, a test stream separator in the test stream line circuit, with a liquid part and a gas part, and test equipment for testing those with the test flow separator in the parallel-connected test flow line circuit separates gas and liquid streams, characterized in that a well flow separator, which has a liquid part and a gas part, is connected to several well flow lines that have branch lines that go to the test flow separator, that a liquid line runs from the liquid part of the test flow separator to the liquid part of the well flow separator, and that a gas line runs from the gas part of the test flow separator to the gas part of the well flow generator, the arrangement being such that the level in the test flow separator mainly follows the level in the well flow separator.
Ifølge oppfinnelsen foreslås det også at teststrømseparatoren kan være anordnet inne i brønnstrømseparatoren. According to the invention, it is also proposed that the test stream separator can be arranged inside the well stream separator.
Med oppfinnelsen bibeholder man de fordeler som ligger i å arbeide på havbunnen, idet man unngår en testledning til overflaten, en testpumpe og en eventuell testkompressor. Anlegget kan enkelt knyttes til flere brønnstrømmer, dvs. til et manifold hvor flere brønnstrømledninger er tilkoplet, for samlet videreføring til brønnstrømseparatoren. En vesentlig fordel oppnås som følge av at nivået i teststrømseparatoren følger nivået i brønnstrømseparatoren, fordi man derved sparer en egen nivåregulering (måleinstrument, kontrollsløyfe og reguleringsventil) for teststrømseparatoren. The invention maintains the advantages of working on the seabed, avoiding a test line to the surface, a test pump and any test compressor. The plant can easily be connected to several well streams, i.e. to a manifold where several well stream lines are connected, for collective continuation to the well stream separator. A significant advantage is achieved as a result of the level in the test flow separator following the level in the well flow separator, because a separate level regulation (measuring instrument, control loop and control valve) is thereby saved for the test flow separator.
Ifølge oppfinnelsen kan fordelaktig teststrømseparatoren være anbragt inne i brønnstrømseparatoren. Derved sparer man både plass og stålvekt. Teststrømseparatoren kan da også bygges lett, siden den ikke blir utsatt for nevneverdig trykkforskjell . According to the invention, the test stream separator can advantageously be placed inside the well stream separator. This saves both space and steel weight. The test flow separator can then also be built easily, since it is not exposed to significant pressure differences.
Oppfinnelsen skal forklares nærmere under henvisning til tegningene, hvor: Fig. 1 rent skjematisk viser et anlegg ifølge The invention shall be explained in more detail with reference to the drawings, where: Fig. 1 schematically shows a plant according to
oppfinnelsen, og the invention, and
fig. 2 rent skjematisk viser en annen utførelses-form av et anlegg ifølge oppfinnelsen. fig. 2 purely schematically shows another embodiment of a plant according to the invention.
I fig. 1 er en brønnstrømseparator betegnet med 1. Denne separator 1 befinner seg i en undervannsstasjon. Et antall brønnstrømledninger 2,3,4 og 5 kommer fra ikke viste oljebrønner på havbunnen og samles i et manifold 6. Derfra går det en brønnstrømledning eller hovedledning 7 til separatoren 1. Brønnstrømledningen 7 munner i separatoren 1 på i og for seg kjent måte i separatorens gassdel 8. Separatorens væskedel er betegnet med 9. In fig. 1 is a well stream separator denoted by 1. This separator 1 is located in an underwater station. A number of well flow lines 2,3,4 and 5 come from not shown oil wells on the seabed and are collected in a manifold 6. From there a well flow line or main line 7 goes to the separator 1. The well flow line 7 opens into the separator 1 in a manner known per se in the gas part of the separator 8. The liquid part of the separator is denoted by 9.
Separatorens væskedel 9 er tilknyttet en pumpe 10. Separatorens gassdel 8 er tilknyttet en kompressor 11. The liquid part 9 of the separator is connected to a pump 10. The gas part 8 of the separator is connected to a compressor 11.
Fra manifoldet 6 går det en teststrømledning 12 til en teststrømseparator 13. Teststrømledningen 12 munner i teststrømseparatoren 13 i dens gassdel 14. Fra teststrøm-separatorens 13 gassrom 14 går det en strømningsledning 15 til brønnstrømseparatorens 1 gassrom 8. Fra teststrøm-separatorens væskedel 16 går det en strømningsforbindelse 17 til brønnstrømseparatorens 1 væskedel 9. Av arrangementet i fig. 1 går det frem at væskenivået i teststrømseparatoren 13 vil være svært nær væskenivået i brønnstrømseparatoren 1, forutsatt at rørføringen er slik at strømningsmotstanden er liten, og at det ikke gis mulighet for væske- eller gass-låser. From the manifold 6, a test flow line 12 goes to a test flow separator 13. The test flow line 12 opens into the test flow separator 13 in its gas part 14. From the test flow separator 13's gas space 14, a flow line 15 goes to the well flow separator 1 gas space 8. From the test flow separator's liquid part 16 a flow connection 17 to the liquid part 9 of the well stream separator 1. Of the arrangement in fig. 1, it appears that the liquid level in the test flow separator 13 will be very close to the liquid level in the well flow separator 1, provided that the piping is such that the flow resistance is small, and that there is no possibility of liquid or gas locks.
I den gassførende ledning 15 er det innlagt egnet måleutstyr 18. I den vaeskeførende ledning 17 er det på tilsvarende måte innlagt egnet måleutstyr 19 for væskeandelen. In the gas-carrying line 15, suitable measuring equipment 18 is installed. In the liquid-carrying line 17, suitable measuring equipment 19 for the liquid portion is installed in a similar way.
I en praktisk utførelsesform vil volumet som kreves i teststrømseparatoren 13 for å sikre tilstrekkelig separasjon tilsvare 10 min. testproduksjons-volumstrøm. Dette er såpass lite at man kan anta at strømmen ut av teststrømseparatoren til en hver tid er lik strømmen inn til teststrømseparatoren, noe som er en forutsetning for å kunne måle teststrømmen med god nøyaktighet på enkel måte. In a practical embodiment, the volume required in the test stream separator 13 to ensure sufficient separation will correspond to 10 min. test production volume flow. This is so small that it can be assumed that the current out of the test current separator at all times is equal to the current into the test current separator, which is a prerequisite for being able to measure the test current with good accuracy in a simple way.
Det i fig. 2 skisserte anlegg virker på samme måte som anlegget i fig. 1, og det er derfor benyttet de samme henvisningstall for tilsvarende komponenter. Ånleggsmessig har man den forskjellen at teststrømseparatoren 13 er lagt inne i brønnstrømseparatoren 1. Derved sparer man plass og stålvekt. Innsparingen kan illustreres av følgende talleksempel : Nødvendig diameter for brønnstrømseparatoren 1 = 2,6 m Nødvendig diameter for teststrømseparatoren 13 = 1,0 m That in fig. 2 sketched plant works in the same way as the plant in fig. 1, and the same reference numbers have therefore been used for corresponding components. In terms of construction, the difference is that the test flow separator 13 is placed inside the well flow separator 1. This saves space and steel weight. The savings can be illustrated by the following numerical example: Required diameter for the well flow separator 1 = 2.6 m Required diameter for the test flow separator 13 = 1.0 m
For å beholde samme overflateareal i brønnseparatoren 1 med teststrømseparatoren montert inne i brønnstrømseparatoren, må brønnstrømseparatorens diameter i dette talleksempel økes til 2,78 m. Teststrømseparatoren kan dessuten bygges lett, siden den ikke blir utsatt for nevneverdig trykkforskjell. In order to keep the same surface area in the well separator 1 with the test stream separator mounted inside the well stream separator, the diameter of the well stream separator in this numerical example must be increased to 2.78 m. The test stream separator can also be built easily, since it is not exposed to significant pressure differences.
