Description

Rørledningsanordning for borehull.Pipeline device for boreholes.

Foreliggende oppfinnelse angår en rørledningsanordning for borehull, særlig for et stigerør eller forbindelsesrør til bruk ved kontinentalsokkel-boring, med rørdeler av fiberforsterket plast. The present invention relates to a pipeline device for boreholes, in particular for a riser or connecting pipe for use in continental shelf drilling, with pipe parts made of fibre-reinforced plastic.

Ved kontinentalsokkel-boring er rørledningen, på grunn av posisjonsforandring for boreskipet, og på grunn av bølge-bevegelser, utsatt for bøyepåkjenninger, hvilket kan føre til brudd i rørledningen. When drilling on the continental shelf, the pipeline is exposed to bending stresses, due to a change in position for the drilling vessel, and due to wave movements, which can lead to a break in the pipeline.

Av denne grunn er det .kjent å anordne leddforbindelser mellom de enkelte rør, i stedet for stive forbindelser. • På denne måte oppnås en sterk reduksjon av bøyemomentet, fordi leddene ikke overfører noe moment. Det er også tidligere kjent å minske bøyemomentene i en rørledning ved å fremstille denne av fiberforsterket plast, slik at bøyemomentene minskes på grunn av elastisiteten. For this reason, it is known to arrange joint connections between the individual pipes, instead of rigid connections. • In this way, a strong reduction of the bending moment is achieved, because the joints do not transmit any moment. It is also previously known to reduce the bending moments in a pipeline by making it of fibre-reinforced plastic, so that the bending moments are reduced due to elasticity.

Formålet med foreliggende oppfinnelse er å komme frem til en enkel forbindelse, som om nødvendig kan frigjøres hurtig, mellom rørdelene av fiberforsterket plast og de øvrige rørdeler. The purpose of the present invention is to arrive at a simple connection, which can be quickly released if necessary, between the pipe parts of fibre-reinforced plastic and the other pipe parts.

I henhold til oppfinnelsen oppnås dette ved at det i over-gangen mellom plastrørene og de øvrige rørdeler er anordnet et mellomrør, på hvilket enden av et fiberforsterket plastrør er anbragt, og at enden av plastrøret er utstyrt med en festeinn-retning. According to the invention, this is achieved by arranging an intermediate pipe in the transition between the plastic pipes and the other pipe parts, on which the end of a fibre-reinforced plastic pipe is placed, and that the end of the plastic pipe is equipped with a fastening device.

Fiberforsterkede rørdeler av plast egner seg for å opptaFiber-reinforced plastic pipe parts are suitable for absorbing

store strekkrefter, og har lav vekt sammenlignet med stålrør. large tensile forces, and has a low weight compared to steel pipes.

Anvendelsen av et mellomrør som rager inn i det fiberforsterkede plastrør medfører en enkel'forbindelse. Ved at plastrøret samtidig trykkes sammen av festeinnretningen, oppnås også tetning i forbindelsesstedet. Derved trengs det ikke noen sær-skilt tetning. The use of an intermediate pipe that protrudes into the fibre-reinforced plastic pipe results in a simple connection. By the fact that the plastic pipe is simultaneously pressed together by the fastening device, a seal is also achieved at the connection point. Thereby, no separate seal is needed.

En særlig fordelaktig utførelsesform består i at mellomrøretA particularly advantageous embodiment consists in the intermediate pipe

er forbundet med den neste rørdel via en bærering. Kraftover-føringen skjer på en enkel måte via bæreringen mellom plast-røret og den neste rørdel. is connected to the next pipe section via a carrier ring. The power transfer takes place in a simple way via the support ring between the plastic pipe and the next pipe part.

I henhold til en utførelsesform oppviser festeinnretningen en ring laget av to eller flere deler, samt en klemring som er ført inn på ringen. According to one embodiment, the fastening device has a ring made of two or more parts, as well as a clamping ring which is inserted onto the ring.

I henhold til oppfinnelsen oppnås en bedre forbindelse og en sikker kraftoverføring ved at, i henhold til en utførelsesform, mellomrøret oppviser en overflate med sagtannprofil i det området det fiberforsterkede plastrør er anbragt rundt. According to the invention, a better connection and a safe power transmission is achieved by, according to one embodiment, the intermediate pipe having a surface with a sawtooth profile in the area around which the fibre-reinforced plastic pipe is placed.

Det er også fordelaktig at enden av det fiberforsterkede rørIt is also advantageous that the end of the fibre-reinforced tube

er avstivet ved hjelp av en eller flere metallringer innleiret i rørveggen. is braced using one or more metal rings embedded in the pipe wall.

I henhold til oppfinnelsen kan videre bæreringen være anordnetAccording to the invention, the support ring can also be arranged

i et rundtgående spor i mellomrøret og den tilhørende rørdel, hvorved skruer festet i rørdelen trykker bæreringen inn i sporet i mellomrøret., in a circumferential groove in the intermediate pipe and the associated pipe part, whereby screws fixed in the pipe part press the bearing ring into the groove in the intermediate pipe.,

Denne anordning av bæreringen gir god kraftoverføring mellom plastrøret og rørdelen. This arrangement of the support ring provides good power transmission between the plastic pipe and the pipe part.

For å lette demontering er det fordelaktig av bæreringen laget av to eller flere deler er utstyrt med gjengede hull i omkretsen. To facilitate disassembly, it is advantageous for the support ring made of two or more parts to be equipped with threaded holes in the circumference.

For demontering trengs derved bare å skrus en skrue et stykke inn i de gjengede hull. De enkelte deler av bæreringen kan derved trekkes ut av det rundtgående spor på mellomrøret og inn i sporet i rørdelen, hvorved forbindelsen med dette opp-heves. For disassembly, it is therefore only necessary to screw a screw a bit into the threaded holes. The individual parts of the support ring can thereby be pulled out of the circumferential groove on the intermediate pipe and into the groove in the pipe part, whereby the connection with this is lifted.

Det er videre fordelaktig at det fiberforsterkede plastrør på inner- og yttersiden er påført et beskyttende lag av myk plast. It is also advantageous that the fibre-reinforced plastic tube is coated with a protective layer of soft plastic on the inside and outside.

Vanligvis vil det for plastrørene anvendes en glassfiberforsterket plast. Denne er imidlertid noe sprø, slik at det ved føring av borestrengen inn og ut kan oppstå riss eller rifter på grunn av de skarpe kanter på borkronen. Av denne grunn beskyttes plastrøret av et lag av mykere plast, med bedre egen-skaper med hensyn til å tåle slike påkjenninger, slik at det ikke oppstår noen svekkelse av røret. Usually, a glass fiber reinforced plastic will be used for the plastic pipes. However, this is somewhat brittle, so that when the drill string is guided in and out, cracks or tears may occur due to the sharp edges of the drill bit. For this reason, the plastic pipe is protected by a layer of softer plastic, with better properties with regard to withstanding such stresses, so that no weakening of the pipe occurs.

I det følgende skal oppfinnelsen beskrives nærmere ved hjelp av et utførelseseksempel, under henvisning til den vedføyde tegning. In what follows, the invention will be described in more detail by means of an embodiment, with reference to the attached drawing.

Røret 1 av fiberforsterket plast oppviser på sin ende 2. en for-tykning. Røret 1 består av glassfiberforsterket plast, og er med sin ende 2 anbragt rundt et mellomrør 3. For å bedre forbindelsen oppviser mellomrøret 3 en overflate 4 med sagtannprofil. For forsterkning, er det i fortykningen 2 innleiret en eller flere koniske metallringer 17. Over enden 2 av røret 1 er en av monteringstekniske grunner todelt ring 5 anbragt. Den todelte ring 5 holdes ved hjelp av en nese 16 i et konisk spor i røret 9, og strammes ved hjelp av en klemring 6 med en likeså todelt trykkring 7 og skruer 8. På denne måte unngås at plast-materialet kan unnvike. Dessuten dannes det derved også en . tetning for forbindelsen. The tube 1 of fibre-reinforced plastic exhibits a thickening at its end 2. The pipe 1 consists of glass fiber reinforced plastic, and its end 2 is placed around an intermediate pipe 3. To improve the connection, the intermediate pipe 3 has a surface 4 with a sawtooth profile. For reinforcement, one or more conical metal rings 17 are embedded in the thickening 2. Above the end 2 of the pipe 1, a two-part ring 5 is arranged for assembly technical reasons. The two-part ring 5 is held by means of a nose 16 in a conical groove in the tube 9, and is tightened by means of a clamping ring 6 with an equally two-part pressure ring 7 and screws 8. In this way, it is avoided that the plastic material can escape. In addition, a . seal for the connection.

Mellom røret 9,.som skal forbindes med plastrøret 1, og mellom-røret 3 er anordnet en bærering 10. Bæreringen 10, som av monteringstekniske grunner er todelt eller delt i flere deler, ligger med en halvdel i et spor 11 i omkretsen av mellomrøret 3 og med den annen halvdel i et spor 12 i røret 9. Skruer 13 som er fordelt rundt omkretsen av røret 9 trykker bæreringen 10 inn i sporet 11 på mellomrøret 3, og det dannes således en kraftoverførende forbindelse mellom røret 9 og plastrøret 1. Between the pipe 9, which is to be connected to the plastic pipe 1, and the intermediate pipe 3, a support ring 10 is arranged. The support ring 10, which for assembly technical reasons is divided into two parts or divided into several parts, lies with one half in a groove 11 in the circumference of the intermediate pipe 3 and with the other half in a groove 12 in the tube 9. Screws 13 which are distributed around the circumference of the tube 9 press the carrier ring 10 into the groove 11 on the intermediate tube 3, and a power-transmitting connection is thus formed between the tube 9 and the plastic tube 1.

Dersom forbindelsen skal løses, er det bare nødvendig å fjerne skruene 13 og skru skruer med mindre diameter inn i de gjengede hull 14 i bæreringen, slik at delene av bæreringen kan trekkes helt inn i sporet 12 i røret 9. På denne måte løses forbindelsen mellom plastrøret 1 og røret 9. If the connection is to be released, it is only necessary to remove the screws 13 and screw screws of smaller diameter into the threaded holes 14 in the support ring, so that the parts of the support ring can be pulled completely into the groove 12 in the pipe 9. In this way, the connection between plastic pipe 1 and pipe 9.

Plastrøret 1 er på inner- og yttersiden påført et beskyttende lag 15 av myk plast. Til dette kan anvendes polyetylen. The plastic pipe 1 has a protective layer 15 of soft plastic applied to the inside and outside. Polyethylene can be used for this.
