Description

Den foreliggende oppfinnelse vedrører en beholder for transport og lagring av olje-/gassprøver, etc, omfattende et beholderlegeme med endestykker og et innvendig anordnet, bevegbart stempel, ved hver ende av beholderen anordnede, gjengede boringer e.l. for tilkobling av slanger e.l. for tilførsel av henholdsvis motrykksvæske og olje/gass, samt en i tilknytning til hver av slangetilkoblingene anordnet ventil. The present invention relates to a container for the transport and storage of oil/gas samples, etc., comprising a container body with end pieces and an internally arranged, movable piston, at each end of the container arranged, threaded bores, etc. for connecting hoses etc. for the supply of back pressure liquid and oil/gas respectively, as well as a valve arranged in connection with each of the hose connections.

Ved boring etter olje og gass blir automatiske prøvetakere sendt ned i borehullet for henting av prøver. Prøvene blir overført til transportbeholdere som sendes til analyse-laboratoriet. Prøver fra olje/gass-separatorer overføres også til transportbeholdere for forsendelse til laboratoriet. Enkelte prøver vil oppbevares i en rekke år og det stilles derfor store krav til beholdernes diffusjonstetthet. When drilling for oil and gas, automatic samplers are sent down the borehole to collect samples. The samples are transferred to transport containers which are sent to the analysis laboratory. Samples from oil/gas separators are also transferred to transport containers for shipment to the laboratory. Certain samples will be stored for a number of years and therefore great demands are placed on the containers' diffusion density.

For å få representative prøver er det viktig at beholderne er rene, sterile og fri for luft. De beholdere som vanligvis brukes på dette området i dag er basert på bruk av kvikksølv til å fortrenge luften i beholderne. Ved påfylling av olje/gass vil kvikksølvet fortrenges og overføres til en ekstra beholder for oppsamling. Ved bruk av kvikksølv praktiseres det pr. i dag strenge sikkerhetstiltak. Det området der overføringen av olje/gass til transportbeholderne foregår, blir avsperret. Operatørene må bruke spesielle verneklær og gassmasker, og undergå legeundersøkelse In order to obtain representative samples, it is important that the containers are clean, sterile and free of air. The containers that are usually used in this area today are based on the use of mercury to displace the air in the containers. When filling up with oil/gas, the mercury will be displaced and transferred to an additional container for collection. When using mercury, it is practiced per today strict security measures. The area where the transfer of oil/gas to the transport containers takes place will be cordoned off. The operators must wear special protective clothing and gas masks, and undergo a medical examination

(urinprøve) både før og etter overføringene. Kvikksølv er giftig og representerer således et miljøproblem. (urine sample) both before and after the transfers. Mercury is toxic and thus represents an environmental problem.

En slik type beholder er tidligere beskrevet i norsk patent nr. 160164. Den består av et hult legeme med inn- og utløpsåpninger på hver side av beholderen. Beholderen er sammensatt av to halvdeler der en metallmembran deler det hule legemet i to kammer. Beholderen kan ha en indre foring hvor membranen er sveiset fast mellom de to foringshalv-delene. Inn-/utløpsåpningene er anordnet vinkelrett på membranen. Membranen bøyer seg i utgangspunktet mot den ene beholderhalvdelen. Under fylling av olje i beholderen vil membranen vrenges over til motsatt side. Such a type of container was previously described in Norwegian patent no. 160164. It consists of a hollow body with inlet and outlet openings on each side of the container. The container is composed of two halves where a metal membrane divides the hollow body into two chambers. The container can have an inner lining where the membrane is welded between the two lining halves. The inlet/outlet openings are arranged perpendicular to the membrane. The membrane initially bends towards one container half. When filling the container with oil, the membrane will be turned over to the opposite side.

En slik beholder må kunne brukes over et meget vidt trykk-område fra ca. 0.5 - 700 bar. Beholderne testes ved et trykk på over 1000 bar. Ved bruk av beholderen som beskrevet i norsk patent 160164 fikk man problemer med lekkasjer ved trykkprøving. Videre ble det funnet at valg av membran-materialer er svært viktig. Ved bruk av stålmembraner måtte membrantykkelsen reduseres så kraftig at vrengningsforløpet var umulig å styre. Selv med membrantykkelser under 5 mm var differansetrykket over membranen så høyt at den kun egner seg til bunnhullprøver. Such a container must be able to be used over a very wide pressure range from approx. 0.5 - 700 bar. The containers are tested at a pressure of over 1000 bar. When using the container as described in Norwegian patent 160164, there were problems with leaks during pressure testing. Furthermore, it was found that the choice of membrane materials is very important. When using steel membranes, the membrane thickness had to be reduced so much that the twisting process was impossible to control. Even with membrane thicknesses below 5 mm, the differential pressure across the membrane was so high that it is only suitable for bottom hole tests.

Fra søkerens egen norske patent nr. 165615 er det videre kjent en vesentlig forbedret løsning av ovennevnte type der beholderen består av to semisfæriske beholderdeler med en metallmembran festet mellom de to halvdelenes flensparti og hvor membranen ved sitt ytre parti også utgjør pakningen mellom de to beholderhalvdelene. From the applicant's own Norwegian patent no. 165615, a significantly improved solution of the above-mentioned type is also known where the container consists of two hemispherical container parts with a metal membrane attached between the flange part of the two halves and where the membrane at its outer part also forms the gasket between the two container halves.

Denne kjente løsningen har vunnet stort innpass i markedet og har i det vesentlige eliminert bruken av kvikksølvbeholdere. Det er imidlertid en ulempe med denne nye type membran-beholder at den er relativt tung og noe dyr å rengjøre og klargjøre for gjenbruk. This well-known solution has gained wide acceptance in the market and has essentially eliminated the use of mercury containers. However, a disadvantage of this new type of membrane container is that it is relatively heavy and somewhat expensive to clean and prepare for reuse.

Med foreliggende oppfinnelse er man kommet frem til en beholder som har stor styrke, men som er meget lettere og meget enklere å rengjøre enn de kjente løsningene. With the present invention, a container has been arrived at that has great strength, but is much lighter and much easier to clean than the known solutions.

Beholderen i henhold til oppfinnelsen baserer seg på en sylinder/stempel type løsning som angitt innledningsvis, og er kjennetegnet av en i beholderen konsentrisk anordnet stang hvortil endestykkene er festet, idet stempelet og eventuelt en blandering er glidbart anordnet på stangen. The container according to the invention is based on a cylinder/piston type solution as indicated at the outset, and is characterized by a concentrically arranged rod in the container to which the end pieces are attached, the piston and possibly a mixing ring being slidably arranged on the rod.

Det uselvstendige krav 2 angir fordelaktige trekk ved oppfinnelsen. The independent claim 2 indicates advantageous features of the invention.

Oppfinnelsen skal i det etterfølgende beskrives nærmere ved hjelp av eksempel og under henvisning til figurene hvor: Fig. 1 viser i tverrsnitt en beholder i henhold til oppfinnelsen. Fig. 2 viser i snitt selve beholderlegemet med en beholderstang, men uten endestykker. Fig. 3 viser i snitt en deleoppstilling av beholderens øvre endestykke med ventiler, samt stempel og håndtak. Fig. 4 viser i snitt det nedre endestykket med ventiler. In what follows, the invention will be described in more detail by means of an example and with reference to the figures where: Fig. 1 shows in cross-section a container according to the invention. Fig. 2 shows in section the container body itself with a container rod, but without end pieces. Fig. 3 shows in section a partial layout of the container's upper end piece with valves, as well as piston and handle. Fig. 4 shows in section the lower end piece with valves.

Som vist i Fig. 1 består beholderen i henhold til oppfinnelsen i grove trekk av et hovedsakelig sylindrisk beholderlegeme med et øvre og nedre endestykke 3,4 som hver er forbundet med en i beholderlegemet konsentrisk anordnet stang 2, samt et stempel 5 og en blandering 6 som er innrettet til å forskyves mellom øvre og nedre posisjoner i beholderen langs stangen 2. As shown in Fig. 1, the container according to the invention roughly consists of a mainly cylindrical container body with an upper and lower end piece 3,4, each of which is connected to a concentrically arranged rod 2 in the container body, as well as a piston 5 and a mixing ring 6 which is arranged to be displaced between upper and lower positions in the container along the rod 2.

Sylinderen 1 og stangen 2 er nærmere vist i Fig. 2. Som det fremgår, er stangen 2 ved endene forsynt med gjengede partier 7,8 for feste av endestykkene, jf. senere avsnitt. The cylinder 1 and the rod 2 are shown in more detail in Fig. 2. As can be seen, the rod 2 is provided at the ends with threaded parts 7,8 for attaching the end pieces, cf. later section.

Komponentene som inngår i øvre del av beholderen, som er vist i sammenstilling i Fig. 1, er nærmere vist i utstrukket form i Fig. 3. Som det kan ses av disse figurene, er stempelet forsynt med tetningsringer 9,10 mot henholdsvis beholderen 1 og stangen 2. Rommene som dannes over eller under stempelet 5 er således adskilt fra og fysisk tette i forhold til hver-andre under tømming og fylling av beholderen. Like over stempelet er det forskyvbart anordnet en blandering 6 som er innrettet til å forskyves fritt langs stangen 2 (se senere avsnitt). Denne blanderingen passer inn i et tilordnet rom mellom stempelet 5 og øvre endestykke 3 når stempelet er i øvre posisjon (se Fig. 1). The components that form part of the upper part of the container, which is shown assembled in Fig. 1, are shown in more detail in extended form in Fig. 3. As can be seen from these figures, the piston is provided with sealing rings 9,10 against the container 1 respectively and the rod 2. The rooms formed above or below the piston 5 are thus separated from and physically sealed in relation to each other during emptying and filling of the container. A mixing ring 6 is displaceably arranged just above the piston, which is designed to move freely along the rod 2 (see later section). This mixing ring fits into an assigned space between the piston 5 and upper end piece 3 when the piston is in the upper position (see Fig. 1).

Det øvre endestykket 3 utgjøres av et sirkulært skiveformet legeme med en diameter som passer inn i den innvendige diameteren i beholderlegemet 1, men med en flens 11 som er innrettet til å ligge an mot enden av beholderlegemet 1. Endestykket 3 er forsynt med spor for pakninger 12 som tetter mot beholderlegemet 1, og fastholdes i beholderlegemet 1 ved hjelp av en låseskrue 13 som strekker seg gjennom beholderlegemet ved dets ende. The upper end piece 3 consists of a circular disk-shaped body with a diameter that fits into the internal diameter of the container body 1, but with a flange 11 which is arranged to rest against the end of the container body 1. The end piece 3 is provided with grooves for gaskets 12 which seals against the container body 1, and is retained in the container body 1 by means of a locking screw 13 which extends through the container body at its end.

I endestykkets overside er det anordnet gjengede 16,17 boringer 14,15 for innskruing av henholdsvis et koblings-legeme 18 og et ventillegeme 19. In the upper side of the end piece there are arranged threaded 16,17 bores 14,15 for screwing in a coupling body 18 and a valve body 19, respectively.

Hver av legemene 18,19 er forsynte med spor for pakninger 20 respektive 21 og øvre gjengede partier 22 respektive 23 som er komplementære med gjengene 16,17 i boringene 14,15. Each of the bodies 18,19 is provided with grooves for gaskets 20 and 21, respectively, and upper threaded parts 22 and 23, respectively, which are complementary to the threads 16,17 in the bores 14,15.

Koblingslegemene 18 er forsynt med en boring 24 med innvendige gjenger 25 (se fig. 3) for tilkobling av en slange el.l. (ikke vist) ved avtapping av olje/gass fra beholderen, eller for innskruing av en propp 26 for avblinding av åpningen når beholderen er under lagring eller transport. The coupling bodies 18 are provided with a bore 24 with internal threads 25 (see fig. 3) for connecting a hose or the like. (not shown) when draining oil/gas from the container, or for screwing in a plug 26 to blind the opening when the container is being stored or transported.

Ventillegemet på sin side er forsynt med en boring 27 for en ventil 35 for stenging og åpning av forbindelsen mellom beholderens indre lagringsrom og tilkoblingsboringen 24. Ventilen består av en ventilnålskrue 29 som er innrettet til å ligge an mot et ventilsete 28 i boringen 27, en gjenget ventilskive 31 for ventilskruen 27, samt en låseskive 32 med utvendige gjenger 33 for innskruing i boringen 27 som har komplementære gjenger 34. The valve body, on the other hand, is provided with a bore 27 for a valve 35 for closing and opening the connection between the container's internal storage space and the connection bore 24. The valve consists of a valve needle screw 29 which is arranged to rest against a valve seat 28 in the bore 27, a threaded valve disc 31 for the valve screw 27, as well as a locking disc 32 with external threads 33 for screwing into the bore 27 which has complementary threads 34.

Mellom ventilen 35 og tilkoblingsboringen 24, er det kommunikasjon via boringer 36,37 og ringspor 38 i stangen 2. En ytterligere boring 39 strekker seg fra ventilen og munner ut i beholderens indre. Between the valve 35 and the connection bore 24, there is communication via bores 36,37 and annular groove 38 in the rod 2. A further bore 39 extends from the valve and opens into the interior of the container.

Det øvre endestykket fastholdes til stangen 2 ved hjelp av en hettemutter 4 0 med innvendige gjenger 41, idet endestykket 3 presses til anlegg mot et skulderparti 42 på stangen 2 (se også Fig. 2). Hettemutteren er ellers forsynt med en boring 4 3 for innføring av et håndtak i form av en fortrinnsvis langstrakt, sirkulær stang 44. The upper end piece is fixed to the rod 2 by means of a cap nut 40 with internal threads 41, the end piece 3 being pressed into contact with a shoulder part 42 on the rod 2 (see also Fig. 2). The cap nut is otherwise provided with a bore 4 3 for inserting a handle in the form of a preferably elongated, circular rod 44.

Det nedre endestykket 4 (se Fig. 1 og Fig. 4) består av et sirkulært skiveformet legeme som har spor for pakninger 4 6 og som er innrettet til å ligge tettende an mot innsiden av beholderen 1. Dette nedre endestykket har tilsvarende ventiler 35 og tilsvarende tilkoblingsboring 24 med innvendige gjenger 25 for tilkobling av en slange (ikke vist) eller propp 26, som omtalt i det foranstående når det gjelder det øvre endestykket. Kommunikasjonen mellom ventilen 35 og tilkoblingsboringen 24 er imidlertid litt forskjellig fra det øvre endelokket, idet det er anordnet boringer 47 respektive 4 8 som strekker seg radialt utad og som er forbundet med et ringspor 49 i endestykket 4. The lower end piece 4 (see Fig. 1 and Fig. 4) consists of a circular disk-shaped body which has grooves for gaskets 4 6 and which is arranged to lie tightly against the inside of the container 1. This lower end piece has corresponding valves 35 and corresponding connection bore 24 with internal threads 25 for connecting a hose (not shown) or plug 26, as discussed above in relation to the upper end piece. The communication between the valve 35 and the connection bore 24 is, however, slightly different from the upper end cap, in that bores 47 and 4 8 respectively are arranged which extend radially outwards and which are connected by an annular groove 49 in the end piece 4.

Det nedre endestykket er innrettet til å fastholdes til stangen 2 ved hjelp av en gjengeforbindelse 50,8 (se henholdsvis fig. 4 og 2) i respektive endestykket 4 og stangen 2, idet endestykket er innrettet til å presses i anlegg mot et skulderparti 51 på bolten. The lower end piece is designed to be fixed to the rod 2 by means of a threaded connection 50,8 (see Fig. 4 and 2 respectively) in the respective end piece 4 and the rod 2, the end piece being designed to be pressed into contact against a shoulder part 51 on the bolt.

Ved sammenstilling av beholderen i henhold til oppfinnelsen, tres først stempelet 5 og blanderingen 6 inn på stangen 2. Deretter festes endestykkene 3 og 4 til stangen som forklart i det foranstående. When assembling the container according to the invention, first the piston 5 and the mixing ring 6 are threaded onto the rod 2. Then the end pieces 3 and 4 are attached to the rod as explained above.

Ventilene 35 og proppene 26 kan være montert i endestykkene på forhånd eller etterpå. The valves 35 and the plugs 26 can be mounted in the end pieces beforehand or afterwards.

Stempel 5, blandering 6 og endestykkene 3 og 4 holdes nå sammen som en enhet av stangen 2 og føres inn i beholderen ovenfra (se Fig. 1) til flensen 11 ligger an mot beholderens øvre ende. Låseskruen 13 kan nå settes inn og dermed fast-holde den innsatte enheten i beholderen. The piston 5, mixing ring 6 and the end pieces 3 and 4 are now held together as a unit by the rod 2 and introduced into the container from above (see Fig. 1) until the flange 11 rests against the upper end of the container. The locking screw 13 can now be inserted and thus hold the inserted unit in the container.

Ved rengjøring tas låseskruen ut, og enheten med stempelet blanderingen og endestykkene kan tas ut og rengjøres på en enkel måte. Dette representerer en vesentlig fordel med oppfinnelsen. En annen fordel er at alle kreftene som påvirker endelokkene som følge av innvendig trykk i beholderen, opptas alene av stangen 2 og blir ikke overført til beholderlegemet 1. Videre blir de radielle kreftene overført og opptatt alene av beholderlegemet 1. When cleaning, the locking screw is removed, and the unit with the piston, the mixing ring and the end pieces can be removed and cleaned in a simple way. This represents a significant advantage of the invention. Another advantage is that all the forces that affect the end caps as a result of internal pressure in the container are absorbed by the rod 2 alone and are not transferred to the container body 1. Furthermore, the radial forces are transferred and absorbed by the container body 1 alone.

Oppfinnelsen virker ellers på følgende måte (se Fig. 1). The invention otherwise works in the following way (see Fig. 1).

En mottrykksvæske, for eksempel glykol, føres i utgangspunktet inn i beholderen 1 gjennom en ledning (ikke vist) via boringen 24 (proppen er tatt ut) i det nedre endestykket 4 gjennom kanalen 47, til ringrommet 49, videre til kanalen 48 og via ventilen 35 som er åpen. Stempelet 5 føres nå oppover av glykolen sammen med ringen 6 til det ligger an mot det øvre endestykket. A back pressure liquid, for example glycol, is initially fed into the container 1 through a line (not shown) via the bore 24 (the plug is removed) in the lower end piece 4 through the channel 47, to the annulus 49, on to the channel 48 and via the valve 35 which is open. The piston 5 is now guided upwards by the glycol together with the ring 6 until it rests against the upper end piece.

Beholderen er nå klar til å tilføres en prøve av olje eller gass. The container is now ready to add a sample of oil or gas.

En olje-/gasslange kobles til boringen 24 i det øvre endestykket 3. Ventilene 35 i begge endestykkene holdes i utgangspunktet stengt. Ventilen 35 i det øvre endestykket åpnes helt, mens tilsvarende ventil i det nedre endestykket åpnes litt for å slippes ut mottrykksvæske. Olje vil nå strømme inn i beholderen. Når all mottrykksvæsken er tappet ut, vil stempelet være i nedre posisjon og ligge an mot det nedre endestykket 4. An oil/gas hose is connected to the bore 24 in the upper end piece 3. The valves 35 in both end pieces are initially kept closed. The valve 35 in the upper end piece is opened completely, while the corresponding valve in the lower end piece is opened slightly to release back pressure liquid. Oil will now flow into the container. When all the back pressure liquid has been drained, the piston will be in the lower position and rest against the lower end piece 4.

Beholderen vil da være fylt med olje/gass og ventilen 35 kan stenges og proppene 26 kan skrues på plass. Ved uttak av olje/gass fra beholderen, vil det være hensiktsmessig først å snu beholderen opp/ned noen ganger. Derved vil blanderingen 6, ved hjelp av tyngdekraften, føres frem og tilbake langs stangen 2 slik at innholdet (oljen/gassen) i beholderen blandes godt. En tappeslange kobles til boringen 24 i det øvre endestykket 3 og ventilen 35 åpnes. En ytterligere slange for tilførsel av trykksatt mottrykksvæske kobles til boringen 2 6 i det nedre endestykket 4 og ventilen 35 åpnes etter behov slik at stempelet ved hjelp av mottrykksvæsken presses oppover og oljen/gassen presses ut av beholderen. Når beholderen er tømt, vil enheten med stangen 2 påmontert endestykkene 3,4, stempelet 5 og blanderingen 6 kunne tas ut av beholderlegemet 1 og rengjøres for gjenbruk som forklart i det foranstående. The container will then be filled with oil/gas and the valve 35 can be closed and the plugs 26 can be screwed into place. When extracting oil/gas from the container, it will be appropriate to first turn the container upside down/down a few times. Thereby, the mixing ring 6, with the help of gravity, will be moved back and forth along the rod 2 so that the contents (oil/gas) in the container are well mixed. A tap hose is connected to the bore 24 in the upper end piece 3 and the valve 35 is opened. A further hose for the supply of pressurized back pressure fluid is connected to the bore 2 6 in the lower end piece 4 and the valve 35 is opened as needed so that the piston is pushed upwards by means of the back pressure fluid and the oil/gas is pushed out of the container. When the container has been emptied, the unit with the rod 2 mounted on the end pieces 3,4, the piston 5 and the mixing ring 6 can be removed from the container body 1 and cleaned for reuse as explained in the foregoing.
