Claims (9)
1. Perforator (1) omfattende hulladninger (2) og en holdeindretning (3) med huller (4), hvori hulladningerne er indsat og fastholdt, hvor hver individuel hulladning (2) er indkapslet hydraulisk forseglet, holdeindretningen (3) omfatter i det mindste ét rør (6) med en rundtgående overflade (7) med huller (4) anbragt langs i det mindste én skruelinie (5), hvor det i det mindste ene rør (6) har en vægtykkelse imellem 2 og 8 mm, hvor det i det mindste ene rør (6) omfatter adskillige rør (6), som er indbyrdes forbundet ved deres endeflader (8) via forbindelseselementer, hvor det i det mindste ene rør (6) er konfigureret til at bære mere end 1,5 tons trækbelastning eller mere end 2,5 tons trykbelastning i den langsgående retning for røret (6), og og perforatoren (1) er konfigureret til at blive indsat i et borehul eller rørsystemet i et borehul, idet borehullet eller rørsystemet i borehullet har en indvendig diameter på højst to gange en udvendig diameter på perforatoren (1), hvor den udvendige diameter inkluderer hulladningerne (2); og perforatoren (1) har en længde før detonering, og hvor, efter-detonering af hulladningerne (2), perforatoren (1) indsat i borehullet nedbrydes i fragmenter, som danner en udfældning i borehullet, hvis totale højde kun udgør omkring 10%-20% af længden før detonering, idet perforatoren (1) er uden et udvendigt hus.
2. Perforatorsystem ifølge krav 1, kendetegnet ved, at det i det mindste ene rør (6) omfatter adskillige rør (6), som er indbyrdes forbundet ved deres endefladeer (8) via forbindelseselementer, og længden af alle rør (6), som er indbyrdes forbundet, fortrinsvis er imellem 15 og 100 m, mere foretrukkent imellem 30 og 80 m, mest foretrukkent 50 m.
3. Perforatorsystem ifølge krav 1 eller 2, kendetegnet ved, at hullerne (4) er anbragt på 3 til 6, fortrinsvis 3 til 4 parallelt forløbende skruelinier (5).

7. Perforatorsystem ifølge ethvert af kravene 2 til 6, kendetegnet ved, at hvert rør (6) har en længde imellem 1 m og 6 m.
8. Perforatorsystem ifølge ethvert af kravene 1 til 7, kendetegnet ved, at centrere for alle hullerne (4) er anbragt i planer (E1, E2, E3), som er vinkelret på den langsgående akse L for det i det mindste ene rør (6), og strækker sig indbyrdes parallelt, og hvert af de to tilstødende planer er anbragt med den samme indbyrdes afstand L1, og det samme antal huller (4) eller disses centre er anbragt på alle planer, og centrene for hullerne i ét plan E1 er forskudt fra centrene for hullerne i de tilstødende planer E2 og E3, med henblik på at forøge antallet af hulladninger (2) eller ladningstætheden.
9. Perforatorsystem ifølge ethvert af kravene 1 til 8, kendetegnet ved, at materialet af det i det mindste ene rør (6) består af rustfrit stål, aluminium, støbejern eller plast omfattende epoxyharpiks.
