Description

PATENTKRAV 1. Brøndboringspakningselement, kendetegnet ved et ekspanderbart pakningselement (17) til tætning af et ringvolumen, en aktuator (16) til at ekspandere pakningselementet til funktionsmæssigt indgreb på tværs af ringvolumenet og et elektrisk styrbart fluidum til at styre funktionen af aktuatoren. 2. Brøndboringspakningselement ifølge krav 1, hvori det elektrisk styrbare fluidum aktiveres af et magnetisk felt til at ekspandere pakningselementet. 3. Brøndboringspakningselement ifølge krav 2, hvori det styrbare fluidum er indesluttet i et ekspanderbart kammer (30). 4. Brøndboringspakningselement ifølge krav 3, hvori det ekspanderbare kammer et elastomert blæreelement, 5. Fluidumstrømningsventil, kendetegnet ved et hængslet klapelement (56) til selektivt at forhindre fluidumstrømning igennem en strømningskanal i et ventillegeme (50), et stempelelement (60) til at dreje klappen i en første retning omkring en hængslings-akse under forspændingen af et eftergiveligt element (64), hvilket stempel fungerer i et kammer 62, som er fyldt med et styrbart fluidum, en elektromagnetisk vikling (68) i nærheden af kammeret og et elektrisk kredsløb til selektivt at aktivere den elektromagnetiske vikling for at modificere viskositeten for det styrbare fluidum for at give plads til forskydning af stemplet imod det nævnte fluidum under forspændingen af det eftergivelige element. 6. Fluidumstrømningsventil, kendetegnet ved et hængslet klapelement (72) til retningsmæssig styring af fluidumstrømning igennem en strømningskanal i et ventillegeme (76) ved drejning imellem en første og en anden strømningsstyreposition, et selektivt indgribende blokeringselement (70) til at forhindre rotationsbevægelse af klapelementet (72) fra en første position, hvilket blokeringselement (70) omfatter en eftergivelig forspænding (89) derpå i retning imod frigørelse af klapelementet og en styrbar fluidumblok (90), som modvirker den eftergivelige forspænding. 7. Rørpropkonstruktion, kendetegnet ved en propfastholdelseskanal, som i det væsentlige omslutter en fluidumstrømningsboring (101), en elektromagnetisk vikling (103) i nærheden af fastholdelseskanalen og et strømningsboringspropelement (104), som er i indgreb med fastholdelseskanalen, hvilket propelement omfatter en mængde styrbart fluidum indkapslet af en fleksibel membran (106). 8. I hullet placeret brøndboringsværktøj, kendetegnet ved et stopkileindgrebsstempel (16) aktiveringselement, som er placeret til positionsmæssig forskydning fra én af modstående trykzoner, idet den ene trykzone omfatter en selektivt indkoblet elektromagnetisk feltkilde (20) og indeslutter et fluidum, som har elektroaktive rheologiske egenskaber, hvorved aktivering af feltkilden forhindrer forskydning af det nævnte stopkileindgrebsstempelaktiveringselement. 9. I hullet placeret brøndboringsværktøj, kendetegnet ved et elastomert blæreaktiveringselement, som er placeret til en positionsmæssigt forskydning fra en af modstående trykzoner, idet den ene trykzone omfatter en selektivt aktiveret elektromagnetisk feltkilde (20) og omslutter et fluidum, som har elektroaktive rheologiske egenskaber, hvorved aktivering af feltkilden begrænser forskydning af det nævnte elastomere blæreaktiveringselement, 10. I hullet placeret brøndboringsværktøj, kendetegnet ved et pakningselement-ekspansionsstempel-aktiverende element, som er placeret til positionsmæssig forskydning fra én af modstående trykzoner, idet den ene trykzone omfatter en selektivt aktiveret elektromagnetisk feltkilde (20) og omslutter et fluidum, som har elektroaktive rheologiske egenskaber, hvorved aktivering af feltkilden begrænser forskydning af det nævnte pakningselementekspansionsstempel-aktiveringselement. 11.

I hullet placeret brøndboringsværktøj, ifølge krav 11, hvori ventilaktiveringselementet er et klapelement (56). 13. I hullet placeret brøndboringsværktøj, kendetegnet ved et aktiveringselement, som er placeret til positionsmæssig forskydning fra én af modstående trykzoner, idet den ene trykzone omfatter en selektivt aktiveret elektromagnetisk feltkilde (80) og omslutter et fluidum, som har elektroaktive rheologiske egenskaber, hvorved aktivering af feltkilden begrænser forskydningen af aktiveringselementet og hvorved en anden af de modstående trykzoner er forspændt af på stedet foreliggende brøndboringstryk. 14. I hullet placeret brøndboringsværktøj, kendetegnet ved et aktiveringselement, som er placeret til positionsmæssig forskydning fra en af modstående trykzoner, idet den ene trykzone omfatter en selektivt aktiveret elektromagnetisk feltkilde (80) og omslutter et fluidum, som har elektroaktive rheologiske egenskaber, hvorved aktivering af feltkilden begrænser forskydning af aktiveringselementet og hvori aktiveringselementet forhindrer funktionen af et ventilelement. 15.
