APPARAT OG FREMGANGSMÅTE FOR UTFORMING AV ET VINDU ELLER ET OMRISS AV SAMME I ET UTFORET BOREHULLS FORINGSRØR
Denne oppfinnelse vedrører et apparat og en fremgangsmåte for forming av et vindu eller et omriss av et vindu i et utforet borehulls foringsrør.
Praksisen med å produsere olje fra flere radialt spredte re-servoarer gjennom ett enkelt primærborehull har økt dramatisk i de senere år. For å gjøre dette enklere er det blitt utvik-let "startpunkt"-teknologi. Denne teknologi tillater en ope-ratør å bore en generelt vertikal brønn og deretter bore ett eller flere awinklede eller horisontale huller ut fra den brønn ved valgt(e) dybde(r). Siden det innledende vertikale borehull ofte er utforet med en streng av rørformet foring, må det skjæres ut et "vindu" i foringsrøret før boring av "startpunktet". I visse fremgangsmåter ifølge eldre teknikk blir vinduer skåret ut ved bruk av forskjellige typer frese-innretninger i kombinasjon med en ledekile. I disse fremgangsmåter behøves én eller flere "turer" med borestrengen. Riggtid er meget kostbar, og flere turer tar tid og øker fa-ren for at det vil oppstå problemer.
Det er lagt ned betydelig innsats i å forsøke å redusere den totale tid det tar å utforme et vindu i foringsrøret, og den herværende oppfinnelse retter seg mot dette problem.
Fra de amerikanske publikasjoner US 2,587,244 og US 5,355,957 er det kjent anordninger for å utforme et vindu i et forings-rør. Apparatene omfatter en avlang, eksplosiv ladning som ved antennelse vil danne et hull i foringsrøret.
Ifølge et første aspekt ved den herværende oppfinnelse er det tilveiebrakt et apparat til utforming av et vindu eller et omriss av et vindu i foringsrøret i et utforet borehull, hvor nevnte apparat omfatter: termisk middel til utforming av et vindu eller et omriss av et vindu i nevnte foringsrør, hvor det termiske middel omfatter et oksidasjonskammer; og plasseringsmiddel til posisjonering av nevnte termiske middel i nevnte foringsrør, kjennetegnet ved at oksidasjonskammeret er forsynt med i det minste ett utløp, og er innrettet slik at reaksjonsmaterialer i oksidasjonskammeret reagerer for å fremstille tilstrekkelig varme til å bevirke at en varmestråle utgår gjennom det i det minste ene utløp, idet utløpet styrer nevnte varmestråle
Selv om den herværende oppfinnelse primært vedrører utfor-mingen av et vindu for awiksoperasjoner, ville vinduet kunne formes for andre formål.
Det skal bemerkes at den herværende oppfinnelse vedrører ut-formingen av et vindu i et foringsrør, og det skal konstrue-res i motsetning til eldre teknikks prosess med perforering av et foringsrør, hvor en mangfoldighet av tilfeldige små huller blir formet i et rør ved å detonere en sprengladning i foringsrøret.
Typisk vil et vindu ha et tverrsnittsområde på minst 75 cm<2>, fortrinnsvis minst 320 cm<2>, og vanligvis minst 635 cm<2>.
Ifølge et andre aspekt ved den herværende oppfinnelse er det tilveiebrakt en fremgangsmåte til utforming av et vindu eller omrisset av et vindu i foringsrøret i et utforet borehull, hvor fremgangsmåten omfatter: innføring av et oksidasjonskammer som har i det minste ett utløp, i det indre av foringsrø-ret; påvirkning av reaksjonsmaterialer til å reagere i oksidas jonskammeret , slik at de gjennomgår en kraftig oksidasjonsreaksjon som frembringer tilstrekkelig varme til at en varmestråle utgår fra oksidasjonskammeret gjennom utlø-pet; og retting av varmestrålen gjennom utløpet og mot foringsrøret.
Ytterligere trekk ved oppfinnelsen er angitt i de underordne-de krav.
For bedre forståelse av den herværende oppfinnelse vil det nå som eksempel bli vist til den medfølgende tegning, hvor: Fig. 1 er et sideoppriss av et system ifølge den herværende oppfinnelse til opprettelse av borehullsvindu. Fig. 1 viser et apparat 560 med en hul beholder 561 hvor det oppstår en relativt alvorlig oksideringsreaksjon i materialer 565 som avgir tilstrekkelig med varme, slik at en varmestråle564 går ut innenfra beholderen 561 til åpninger eller dyser 562 og deretter til et utløp (eller flere) 563 fra hvilket (hvilke) varmestrålen 564 rettes mot et rørelement som det skal utformes en åpning i. Dysene er valgfrie og blir benyt-tet til å øke utgangshastigheten på reaksjonsproduktet. Oksi-deringsreaksjonen kan, i visse utførelser, være hvilken som helst kjent termitt- eller pyranolreaksjon; også egnede driv-midler, f.eks. kompakte rakettdrivmidler, kan benyttes. Apparatet kan å bli brukt til å opprette en innledende åpning, innledende anslag, innledende vindu, eller ferdig vindu gjennom et rør. Apparatet kan brukes på, brukes med, er løs-bart forbundet med, eller festet nedenfor en fres eller fre-ser for å opprette åpningen. Apparatet kan også brukes på, brukes med, være løsbart forbundet med, eller festet til el ler ovenfor en ledekile, avleder eller vektelement. Systemet på fig. 1 kan beveges vekselvis opp og ned og/eller roteres eller svives fra side til side for å forme en åpning av en ønsket lengdeutstrekning, ønsket sideveis utstrekning og ønsket fasong.
