Claims (16)

  1. PAT E N T K RAV
    1. Borehulsværktøj (10), som kan forbindes med en borestreng, hvilken borestreng er indrettet til fremføring af borevæske igennem dennes indre til en borebit ved dennes nedre ende, hvilket borehulsværktøj omfatter: et hus (19; 34) med en langsgående boring; og et omrørerarrangement (14; 30) placeret i den langsgående boring i huset (34), hvor omrørerarrangementet omfatter en drivsektion (18) med en rotor (22; 36) og et ventilarrangement (20), som er forbundet med rotoren, hvor, under brug, ventilarrangementet selektivt åbnes ved rotation af rotoren for derved at tillade borevæske at strømme fra det indre af borestrengen ved én ende af huset (34) igennem omrørerarrangementet til det indre af borestrengen ved den anden ende af huset, hvorved trykimpulser genereres i borevæsken indeholdt i det indre af borestrengen; kendetegnet ved en bortfjernelig komponent (14, 18, 20; 30, 50) placeret i og blokerende den langsgående boring, hvor under brug den bortfjernelige komponent kan bortfjernes for i det mindste delvis at åbne den langsgående boring for at tillade en operation under boreværktøjet (10) igennem boringen.
  2. 2. Borehulsværktøj ifølge krav 1, hvor den bortfjernelige komponent er en del af omrørerarrangementet (14; 30).
  3. 3. Borehulsværktøj ifølge krav 1, hvor omrørerarrangementet (30) yderligere omfatter en ringformet kanal dannet imellem rotoren (36) og huset (34), og ventilarrangementet (20) omfatter et fluid indløb (56, 58), som tilvejebringer selektiv fluid strømning fra ringkanalen ind i rotoren (36).
  4. 4. Borehulsværktøj ifølge krav 1, hvor den bortfjernelige komponent er placeret indvendigt i rotoren (22; 36).
  5. 5. Borehulsværktøj ifølge krav 1, hvor rotoren (22; 36) er den bortfjernelige komponent.
  6. 6. Borehulsværktøj ifølge krav 1, som yderligere omfatter et stopelement (40), som aksialt begrænser rotoren (36) i forhold til huset (34). 1
  7. 7. Borehulsværktøj ifølge krav 6, hvor stopelementet (40) omfatter en strømningsåbning (42), som tilvejebringer fluid forbindelse imellem huset (34) og omrørerarrangementet (30).
  8. 8. Borehulsværktøj ifølge krav 1, hvor rotoren (36) har et indløb (56) placeret på et excentrisk fremspring (62), og huset (34) har et tætningselement (60), som under brug begrænser en strømning af fluid igennem indløbet (56), når rotoren (36) roterer.
  9. 9. Borehulsværktøj ifølge krav 1, hvor drivsektionen (18) også omfatter en stator (24).
  10. 10. Borehulsværktøj ifølge krav 9, hvor statoren (24) er forbundet med huset (19).
  11. 11. Borehulsværktøj ifølge krav 1, hvor drivsektionen omfatter en eller flere vinger (140) forbundet med rotoren (138).
  12. 12. Borehulsværktøj ifølge krav 1, hvor den bortfjernelige komponent omfatter ventilarrangementet (20).
  13. 13. Borehulsværktøj ifølge krav 1, hvor ventilarrangementet (20) er en radialstrømningsventil, som omfatter et eller flere udløb forbundet med rotoren, som, under brug, periodisk oprettes med en eller flere strømningsåbninger igennem et stationært udvendigt legeme.
  14. 14. Borehulsværktøj ifølge krav 13, hvor den bortfjernelige komponent omfatter rotoren (22; 36), og det udvendige legeme er konfigureret til at tillade operationer igennem boringen derigennem.
  15. 15. Borehulsværktøj ifølge krav 1, hvor ventilarrangementet er en aksialstrømningsventil (135), som omfatter en roterende strømningsplade (136) forbundet med rotoren og en stationær strømningsplade (134) forbundet med huset (142).
  16. 16. Borehulsværktøj ifølge krav 15, hvor den bortfjernelige komponent omfatter både den roterende strømningsplade (136) og den stationære strømningsplade (134). 2
