Description

Denne oppfinnelse angår et telemetrisystem og særlig et telemetrisystem som er egnet for bruk ved overføring av data i et borehull.
Det er ønskelig, ved boring av et undergrunnsborehull i en formasjon, å kunne overføre data langs borehullet. For eksempel der et styrbart boresystem benyttes og nedihullssensorer er anordnet og innrettet til å avgi signaler som er representative f.eks. for boreretningen, er det ønskelige å kunne overføre sig-naldata som er representative for boreretningen, i sanntid, til en operatør som befinner seg ved overflaten.
Det er kjent et antall telemetrisystemer som kan tilveiebringe slik dataover-føring. Slike systemer har imidlertid lett for å bli temmelig kompliserte og dyre, og vil muligens ikke kunne overføre data i sanntid. Der er situasjoner hvor mengden av data som skal overføres er forholdsvis liten og tilveiebringelse av et slikt telemetrisystem kan ikke rettferdiggjøres eller, om det tilveiebringes, blir ikke brukt fullt ut. Det er et formål med oppfinnelsen å tilveiebringe et telemetrisystem av forholdsvis enkel og hensiktsmessig form, egnet for bruk ved slike anvendelser.
US 5182731 A beskriver en hydromekanisk signalsenderfor å generere trykkpulser i et borefluid for å overføre telemetriinformasjon i en brønnloggings-operasjon.
Den foreliggende oppfinnelse vedrører et telemetrisystem for bruk i et boresystem, idet telemetrisystemet omfatter en rotasjonsventil som styrer tilførselen av borefluid eller -slam til et spennpute-stempelarrangement til et brønnverktøy, hvor rotasjonsventilen har et rotasjonsventillegeme og et utløpslegeme, hvor rotasjonsventillegemet innbefatter en åpning som selektivt kommuniserer med en serie åpninger i utløpslegemet for å muliggjøre styring over strømningen av borefluid eller -slam til brønnverktøyet, hvor systemet videre omfatter det å motta data som skal overføres, omkode dataene som en varighet, og styre rotasjonsventilens rotasjon slik at rotasjonsventillegemet til rotasjonsventilen roteres med hensyn til utløpslegemet for nevnte varighet med en forutbestemt rotasjonshastighet for å bevirke dannelse av trykksvingninger eller - bølger i borefluidet eller -slammet for å danne telemetrisignaler, og hvor boresystemet innbefatter minst én nedihullssensor, hvis output omfatter dataene som skal overføres.
Ytterligere utførelsesformer av telemetrisystemet i henhold til oppfinnelsen fremgår av de uselvstendige patentkrav.
Det beskrives et telemetrisystem for bruk i et boresystem innbefattende en dreie- eller rotasjonsventil som styrer tilførselen av borefluid eller slam til et brønnverktøy, hvor systemet omfatter det å motta data som skal overføres, dekode dataene som en varighet, og styre rotasjonsventilens rotasjon slik at rotasjonsventilen roteres for den samme varighet med en forutbestemt rotasjonshastighet for å bevirke dannelse av trykksvingninger eller -bølger i borefluidet eller -slammet.
En har funnet at rotasjon av en rotasjonsventil frembringer trykksvingninger eller -bølger i borefluidet eller slammet som føres til, og gjennom, rotasjonsventilen, ved bruk, og disse svingninger eller bølger kan avføles, f.eks. ved overflaten. Ved riktig styring av rotasjonsventilen, kan disse trykksvingninger eller -bølger brukes til å overføre signaler, uten behov for ytterligere, kompliserte brønnverktøy. Følgelig kan data overføres i sanntid til en operatør ved overflaten.
Systemet innbefatter hensiktsmessig minst én nedihullssensor, hvis output omfatter de data som skal overføres.
Med sikte på å øke mengden av data som kan overføres ved bruk av systemet, kan det velges to eller flere forut bestemte rotasjonshastigheter som hver indikerer outputen fra en respektiv sensor. Alternativt kan dataene omkodes ved bruk av en oppslagstabell, idet et første signal som overføres ved å rotere ventilen i en første varighet med en første rotasjonshastighet brukes til å overføre informasjon relatert til en koordinat i oppslagstabellen, idet et andre signal som overføres ved å rotere ventilen i en andre varighet med en andre, forutbestemt hastighet brukes til å overføre informasjon relatert til en annen koordinat i oppslagstabellen.
Signalet som overføres ved bruk av systemet kan dekodes av operatøren ganske enkelt ved å overvåke for hvor lenge trykksvingningene eller -bølgene ved de forutbestemte frekvenser mottas. Dette kan oppnås manuelt eller automatisk ved bruk av en hensiktsmessig styrt anordning.
Signalene som overføres på dette vis blir lettest identifiserbare når borerøret er stasjonært. Systemet blir derfor hensiktsmessig brukt til å overføre data like etter at brønnverktøyet har fullført sin oppstartingssekvens når pumpene tilfører borefluid eller slam eller er slått på. Imidlertid kan det være mulig å bruke systemet for å overføre data til overflaten på andre tider.
Oppfinnelsen skal ytterligere beskrives, ved hjelp av eksempel, i tilknytning til de medfølgende tegninger, hvor: Fig. 1 er et skjematisk riss som viser en del av en bunnhullsstreng innbefattende et brønnverktøy som styres ved bruk av en rotasjonsventil;
Fig. 2 er et skjematisk riss som viser rotasjonsventilen; og
Fig. 3a og 3b er tabeller som viser to mulige omkodingsteknikker.
Idet det først vises til fig. 1, er det skjematisk vist en del av en bunnhulls-sammenstilling 10 for bruk ved utforming av et borehull 14 i en undergrunnsforma-sjon 12. Sammenstillingen 10 omfatteren borkrone 16 som bæres av en spennenhet 20. En styreenhet 18 kan betjenes for styring av spennenhetens 20 funksjon.
Spennenheten 20 omfatter et hus 22 som er innrettet til å bære en rekke spennputer 24. Hver spennpute 24 kan beveges mellom en inntrukket stilling og en utskjøvet stilling, idet stempelanordninger 26 er innrettet til å skyve hver pute 24 fra dens inntrukne stilling til dens utskjøvne stilling. Stempelarrangementene 26 kan betjenes uavhengig av hverandre, idet tilførsel av fluid under trykk til stempelarrangementene 26 styres ved hjelp av en rotasjons-styreventil 28 i styreenheten 18.
Ved bruk, blir huset 22 båret eller utgjør en del av et borerør eller en borestreng som roteres, f.eks. fra overflaten eller ved hjelp av en brønnmotor nede i borehullet. Hvis stempelanordningene 26 tilføres trykkfluid etter tur, synkront med husets 22 rotasjon, vil det forstås at spennputene 24, etter tur, beveges til sine utskjøvne stillinger. I deres utskjøvne stillinger, hviler putene 24 mot borehullets 14 vegg, og huset 22 påføres en siderettet reaksjonskraft. Ved å styre stempelanordningene 26 på en synkronisert måte med husets 22 rotasjon, vil det forstås at reaksjonskraften virker i en hovedsakelig konsistent retning. Da borkronen 16 er festet til huset 22, vil det forstås at virkemåten til spennenheten på denne måte også resulterer i påføring av en siderettet kraft på borkronen 16, slik at borkronen tvinges til å danne en kurve eller et borehullskne i borehullet 14.
Rotasjons-styreventilen 28 omfatter en "face"-tetningsventil av den type som er skjematisk vist i fig. 2. Ventilen omfatter et skiveformet rotasjonsventillegeme 30 anordnet i et kammer 32 som tilføres borefluid eller -slam, ved bruk, under trykk gjennom borerøret gjennom et innløp 34. I kammeret 32 er det også et utløpslegeme 36, også skiveformet, idet en overflate på ventillegemet 30 ligger an mot en overflate på utløpslegemet 36. Utløpslegemet 36 er utformet med en rekke åpninger 38 som strekker seg fra overflaten som ventillegemet 30 ligger an mot til den motsatte overflate, idet hver åpning kommuniserer med et respektivt utløp 40. Utløpene 40 kommuniserer, ved bruk, med hver sin av stempelanordningene 26. Åpningene 38 i utløpslegemet 36 ligger ved en felles radial posisjon.
Ventillegemet 30 er utformet med en bueformet åpning 42 som strekker seg fra ventillegemets overflate som ligger an mot utløpslegemet 36 til den motsatte overflate av dette og som er anordnet ved den samme radiale posisjon som åpningene 38.
En styreaksel 44 strekker seg inn i kammeret 32 og er forbundet med ventillegemet 30 for å bevirke rotasjonsbevegelse av elementet 30.
Det skal forstås at, ved bruk, vil fluid som strømmer inn i kammeret 32 passere gjennom den bueformede åpning 42 og inn i den av åpningene 38 som korresponderer med denne, idet fluidet strømmer gjennom det respektive utløp 40 til den tilhørende stempelanordning 26. Valget av hvilken, og noen, av utløpene 40 som fluid tilføres ved hjelp av ventilen 28, avhenger av ventillegemets 30 vinkelposisjon som, i sin tur, avhenger av styreakselens 44 vinkelposisjon.
Styreakselen 44 kan roteres ved hjelp av en rekke anordninger. For eksempel kan en hensiktsmessig styrt, elektrisk drevet motor brukes til å drive akselen 44 og derved styre operasjonen av ventilen 28. Alternativt kan styreakselen 44 være forbundet med en hensiktsmessig styrt, rullestabilisert plattform. I begge tilfeller kan akselens 44 bevegelse styres som reaksjon på utgangssignaler fra én eller flere nedihullssensorer 46, f.eks. innrettet til å avføle husets 22 inklinasjon.
Systemer av denne typer er velkjent og deres virkemåte vil derfor ikke bli nærmere beskrevet.
Så lenge styreakselen 44 roteres, dannes trykksvingninger eller -bølger i borefluidet eller -slammet i borerøret når kommunikasjon begynner, og deretter brytes, mellom den bueformede åpning 42 og åpningene 38, etter tur. De trykksvingninger eller -bølger som derved dannes kan avføles ved overflaten eller ved andre steder i avstand fra ventilen 28, særlig på tidspunkter når borerøret ikke roteres.
I samsvar med oppfinnelsen, er disse trykksvingninger eller -bølger utstyrt for å muliggjøre dataoverføring fra bunnhullssammenstillingen, f.eks. til overflaten. For eksempel der sensoren 46 er innrettet til å avgi et signal som er representativt for inklinasjonen til spennenhetshuset 22, blir utgangssignalet fra sensoren 46 omkodet, f.eks. ved bruk av tabellen vist i fig. 3a for å utlede en varighet som er representativ for den avfølte inklinasjon. Rotasjonsventilen 28 blir så satt i rotasjon med en forutbestemt rotasjonshastighet for den utledede varighet, hvorved det overføres en rekke trykksvingninger eller -bølger gjennom borefluidet eller -slammet med en frekvens som er relatert til rotasjonshastigheten til rotasjonsventilen for den utledede varighet. Utstyr plassert på overflaten som er sensitivt for trykksvingningene eller -bølgene i fluidet kan brukes til å sette en operatør i stand til å måle hvor lenge trykkfluktasjonene eller -bølgene ble overført ved den forutbestemte frekvens. Varigheten kan så dekodes for å forsyne operatøren med sanntids-informasjon representativt for husets 22 inklinasjon.
For eksempel hvis utgangssignalet fra sensoren 46 indikerer at huset 22 heller med en vinkel på 2,5 grader, ved bruk av den ovenfor beskrevne teknikk med henvisning til fig. 3a, roteres rotasjonsventilen 28 i et tidsrom på 30 sekunder med den forutbestemte rotasjonshastighet, f.eks. en hastighet som virker til å overføre trykksvingninger eller -bølger ved en frekvens på 6 Hz. Operatøren kan, etter å ha målt at et 6 Hz signal er blitt mottatt i 30 sekunder, sikre, i sanntid, at husets 22 helling er i området 2-3 grader. Det skal forstås at andre rotasjonshastigheter for ventilen 28 kan brukes til å overføre signaler, og at varigheten og området av inklinasjonsvinkler, og forholdet mellom disse, kan velges for å til-passes den anvendelse ved hvilken oppfinnelsen anvendes.
Der to eller flere sensorer er anordnet, kan data, representative for sen-sorenes utgangssignaler overføres, etter tur, f.eks. ved rotasjonsventilen rotert ved ulike rotasjonshastigheter, for derved å fremskaffe en indikasjon på for hvilke para-metere data overføres.
Fig. 3b viser en alternativ omkodingsteknikk som kan brukes til å overføre større datamengder ved bruk av systemet ifølge oppfinnelsen. I dette arrange-ment, omkodes utgangssignalene fra sensorene ved bruk av en oppslagstabell.
Hvis det f.eks. bestemmes at verktøyets arbeidsflatevinkel er 90 grader og avviket er 60%, så vil en ved å bruke oppslagstabellen, vist i fig. 3b, kunne se at denne kombinasjon av parameterverdier skjer i kolonne 3, rad 7 i oppslagstabellen. I dette eksempel overføres kolonnedataene ved å rotere ventilen 28 med en rotasjonshastighet for å generere trykksvingninger eller -bølger ved en frekvens på 4 Hz, og rådata overføres ved å rotere ventilen 28 for å bevirke trykksvingninger eller -bølger ved en frekvens på 6 Hz. For å overføre dataene blir således ventilen rotert for å bevirke overføring av et 4 Hz-signal for 3 tidsenheter, f.eks. 30 sekunder, idet ventilen deretter roteres for å overføre et 6 Hz-signal i syv tidsenheter, f.eks. 70 sekunder. Ved mottak av disse signaler, kan operatøren dekode signalene ved bruk av den samme oppslagstabell for å oppnå, i sanntid, verktøy-arbeidsflate- og awiksdata.
Om ønskelig, kan oppslagstabellen brukes til å overføre verktøystatuskoder eller -ord til operatøren.
Som ovenfor nevnt, blir denne informasjon best overført når borestrengen ikke roteres, og kan hensiktsmessig overføres like etter at brønnverktøyet har fullført sin oppstartingsprosedyre når borefluidpumpene aktiveres etter resirkulering. Det kan imidlertid være mulig å foreta vellykket overføring og mottak av data ved bruk av systemer til andre tider.
Signalet som mottas ved overflaten kan måles ganske enkelt ved at operatøren bestemmer hvor lenge et signal med en forutbestemt frekvens er blitt overført, som han så dekoder. Alternativt kan overflateplassert utstyr brukes til å avføle signaloverføringen ved den forutbestemte frekvens eller de forutbestemte frekvenser, for å måle hvor lenge signalene er overført, for å dekode signalene og for å frembringe et korrekt output for å operatøren.
Evnen til å overføre data i sanntid i samsvar med denne oppfinnelsen, er fordelaktig ved at, sammenliknet med konvensjonelle arrangementer, kan data overføres på en forholdsvis enkel, hurtig og bekvem måte. Data kan således over-føres oftere og mer kostnadseffektivt enn hva som er mulig med konvensjonelle arrangementer. Sanntids-dataoverføringen setter også en operatør i stand til å sikre at nedihullsutstyret arbeider korrekt, at kommunikasjonslenker med nedihullsutstyret funksjonerer, og kan tillate bedre styring over nedihullsutstyr som, f.eks., at avvik fra ønsket bane kan avføles og korrigeres hurtigere. Systemet krever ikke anskaffing av ytterligere nedihullsverktøy eller -utstyr, men kan isteden impliseres ganske enkelt ved hensiktsmessig modifikasjon av styresystemet for et standard brønnverktøy.
Det skal forstås at et område av modifikasjoner og endringer kan utføres ved den ovenfor beskrevne oppfinnelse uten å avvike fra oppfinnelsens ramme.
