Abstract

Trykkcmformer for montering ovenfor borkronen ved den nedre ende av et iborerør for dypboring, særlig etter oj le og gass, og for frembringelse av et forhøyet væsketrykk under utnyttelse av energi i en boreslarostram ned gjennom borerøret, med sikte pi en forsterket borevirkning, fortrinnsvis ved hjelp av en eller flere høytrykkstråler egnet til å ha skjærevirkning i er. omgivende bergart. Et drivorgan (2) er innrettet til å drives av boreslamstrømmen og til å bevege et ventilorgan (4) som styrer et stempelorgan (6) til resiproserende bevegelse med et trykkslag og et returslag. Stempelorgan har på den ene side en forholdsvis stor stempelflate (11) innrettet til under trykkslaget å påvirkes av boreslamtrykket i borerøret, og har på den andre siden en første, motsatt stempelflate (13) som både under trykkslaget og returslaget påvirkes av returtrykket i boreslamstrømmen oppad" utenfor borerøret, og er. annen, motsatt og forholdsvis liten stempelflate (12) som under trykkslaget er innrettet til å frembringe et forhøyet trykk i en mindre del av boreslamstrømmen, idet en enveis ventil (15) tillater avgivelse av denne mindre del av strømmen til en samlekanal (16) som leder frem mot borkronen, mens den store stempelflate (11) under returslaget er innrettet til å utsettes for returtrykket utenfor borerøret og den lille stempelflats (12) for trykket i borerøret.
