Description
Inngreps gjenge lås for borestreng Engaging thread lock for drill string
Flere tradisjonelle service gjenger og låse metoder holder ikke styrken til nyere lisensierte gjenger i borestrenger som resulterer i svake punkter i borestrengen ved vridnings moment og fare for gjengene løsner ved vibrasjoner, slag og høye temperaturer nedihull. Several traditional service threads and locking methods do not hold the strength of newer licensed threads in drill strings, which results in weak points in the drill string during twisting torque and the risk of the threads loosening due to vibrations, impacts and high temperatures downhole.
Alternative gjenge låse metoder er tiltreknings moment, utsatt for løsning ved slag og vibrasjonener. Alternative thread locking methods are tightening torques, subject to loosening by impact and vibrations.
Tiltreknings moment og kjemisk låsing, utsatt for løsning ved høye temperaturer. Tiltreknings moment og sett skruer fra utsiden med kjemisk låsing av sett skruer utsatt for utvendig slitasje, temperatur, slag og vibrasjoner. Tightening torque and chemical locking, subject to dissolution at high temperatures. Tightening torque and set screws from the outside with chemical locking of set screws exposed to external wear, temperature, impact and vibrations.
Dokument: US2005/279513 A1 anses å være nærmestliggende kjente teknikk til søknadsgjenstanden ifølge krav 1. Fra patentlitteratur vises til US 2005/279513 A1 vedrørende et låssystem for borestreng omfattende en øvre rørseksjon med fabrikkerte utvendig langsgående spor; en nedrerørseksjon med fabrikkerte utvendig langsgående spor og koblingsanordninger i ytterside rundt rørene. Document: US2005/279513 A1 is considered to be the closest prior art to the subject of application according to claim 1. From patent literature, reference is made to US 2005/279513 A1 concerning a locking system for a drill string comprising an upper pipe section with fabricated external longitudinal grooves; a lower pipe section with fabricated external longitudinal grooves and coupling devices on the outside around the pipes.
Dokument: US 2017/101829 A1 oppviser en Koplingsanordning (1) og framgangsmåte for å forbinde to borerørseksjoner i en streng (100) av borerørseksjoner sammenføyd av rørkoplinger. Document: US 2017/101829 A1 shows a Coupling device (1) and method for connecting two drill pipe sections in a string (100) of drill pipe sections joined by pipe couplings.
Dokument: WO 2007/010513 A1 oppviser et låssystem for kobling av borkrone med borestreng der systemet omfatter et nedre objekt (3) med utvendig langs gående spor er plassert innvending i øvre objekt (4) med samme antall motgående innvendige langs gående spor. Document: WO 2007/010513 A1 shows a locking system for connecting a drill bit with a drill string, where the system comprises a lower object (3) with an external longitudinal groove is placed inside an upper object (4) with the same number of opposing internal longitudinal grooves.
Ved Inngreps gjenge lås for borestreng brukes ikke tiltrekningsmoment og kan derfor monteres enkelt uten bruk av maskiner bare håndkraft og håndverktøy, tåler høyt vridnings moment og er ikke påvirket av vibrasjoner, slag, temperaturer og utvendig slitasje. With Engreps thread lock for drill string, tightening torque is not used and can therefore be installed easily without the use of machines, only hand power and hand tools, withstands high twisting torque and is not affected by vibrations, impacts, temperatures and external wear.
Dette oppnås i følge oppfinnelsen ved at et bevegelig objekt (2) med fabrikkerte utvendig langs gående spor blir plassert innvending i det øvre objektet (1) med innvendige gjenger hvor motgående innvendinge langs gående spor (4) er fabrikkert med minemal toleranse på sideveis bevegelse og ekstra lengde på innvending spor (4) iforhold til utvendig spor (5) på det bevegelig objektet (2), slik at det kan presses innover i lengde rettingen til endes i det innvendige sporet (4) og ikke komme i konflikt med det nedre objektet (3) med utvenndige gjenger og fabrikkerte motgående tannkrans (6), som skrus med klokken inn i øvre objektet (1) til utvendige gjenge skuldrer møtes, nedre objektet (3) roteres så mot klokken slik at tannkransen (6) i nedre objekt (3) og øvre objektet (1) linjes opp og det bevegelige objektet (2) betjenes via øvre del av øvre objektet (1) og forskyves i lengde rettningen og inn i inngrep med nedre objekt (2) og skaper en sterk vridnings moment overføring. This is achieved according to the invention by a movable object (2) with fabricated external longitudinal tracks being placed facing into the upper object (1) with internal threads, where the counter-aligned objects along the longitudinal tracks (4) are fabricated with minute tolerances on lateral movement and extra length on the inside track (4) in relation to the outside track (5) on the movable object (2), so that it can be pushed inwards in the lengthwise direction until it ends in the inside track (4) and not come into conflict with the lower object (3) with external threads and fabricated opposing ring gear (6), which is screwed clockwise into the upper object (1) until the external thread shoulders meet, the lower object (3) is then rotated counterclockwise so that the ring gear (6) in the lower object ( 3) and the upper object (1) are aligned and the movable object (2) is operated via the upper part of the upper object (1) and is displaced in the length direction and into engagement with the lower object (2) and creates a strong torque transfer.
Kan brukes i borestreng verktøy hvor det er behov for større innvending diameter en standard gjenger i borestrengen har og andre komponenter må plasseres innvendig. Can be used in drill string tools where there is a need for a larger inside diameter than a standard thread in the drill string has and other components must be placed inside.
Låssystemet ifølge oppfinningen er vist på tegninger, der figur 1 er et tverrsnitt av rørdelene separert, figur 2 viser bevegelige objektet (2) montert i øvre objektet (1), figur 3 viser nedre objektet skrudd inn i øvre objektet (1), figur 4 viser bevegelige objektet flyttet inn i inngrep med nedre objektet (3), figur 5 viser sideriss av objektene (1,2,3) fokusert på innvending spor (4), utvendig spor (5) og tannkrans (6). The locking system according to the invention is shown in drawings, where Figure 1 is a cross-section of the pipe parts separated, Figure 2 shows the movable object (2) mounted in the upper object (1), Figure 3 shows the lower object screwed into the upper object (1), Figure 4 shows the moving object moved into engagement with the lower object (3), Figure 5 shows a side view of the objects (1,2,3) focused on the inside track (4), outside track (5) and gear ring (6).
