APPARAT FOR Å STIMULERE EN PETROLEUMSBRØNN OG FRAMGANGSMÅTE FOR Å STIMULERE BRØNNEN APPARATUS FOR STIMULATING A PETROLEUM WELL AND METHOD FOR STIMULATING THE WELL

Oppfinnelsen vedrører et apparat for å stimulere en petroleumsbrønn og framgangsmåte for å stimulere brønnen. The invention relates to an apparatus for stimulating a petroleum well and a method for stimulating the well.

I det etterfølgende beskrives et eksempel på en foretrukket utførelsesform som er anskueliggjort på medfølgende tegninger, hvor: In what follows, an example of a preferred embodiment is described which is illustrated in the accompanying drawings, where:

Fig. 1 viser et skjema av apparatet ifølge oppfinnelsen; og Fig. 1 shows a diagram of the device according to the invention; and

Fig. 2 viser bruk av apparatet ifølge oppfinnelsen i fremgangsmåten ifølge oppfinnelsen. Fig. 2 shows use of the device according to the invention in the method according to the invention.

BESKRIVELSE AV APPARATET IFØLGE OPPFINNELSEN (se Fig. 1): DESCRIPTION OF THE APPARATUS ACCORDING TO THE INVENTION (see Fig. 1):

Apparatet ifølge oppfinnelsen omfatter en væskeringspumpe (4) og en multifasepumpe (5) i serie samt et eget kontrollsystem (2) for disse. Væsketilførsel fra reservoar (1) via fødepumper (3) sør-ger for at pumpene (4) og (5) opererer optimalt. Grunnen for væsketilførsel er at pumpen ikke kan håndtere ren gass. Sammensetningen vil kunne brukes til å dra ned trykk helt ned til vakuum og trykkoppbygning. The apparatus according to the invention comprises a liquid ring pump (4) and a multiphase pump (5) in series as well as a separate control system (2) for these. Liquid supply from reservoir (1) via feed pumps (3) ensures that pumps (4) and (5) operate optimally. The reason for liquid supply is that the pump cannot handle pure gas. The composition can be used to reduce pressure all the way down to vacuum and pressure build-up.

Apparatet er konfigurert for å dra ned trykk, vakuum og trykkoppbygning på flerfasestrømning. The device is configured to reduce pressure, vacuum and pressure build-up on multiphase flow.

Apparatet kan ta trykket helt ned til 0,2 bar absolutt trykk (-0,8 bar) og bygge det opp igjen til øns-ket trykk inn til produksjonsheader (se Fig. 2). The device can take the pressure all the way down to 0.2 bar absolute pressure (-0.8 bar) and build it up again to the desired pressure into the production header (see Fig. 2).

BESKRIVELSE AV FREMGANGSMÅTEN IFØLGE OPPFINNELSEN (se Fig. 2): DESCRIPTION OF THE PROCEDURE ACCORDING TO THE INVENTION (see Fig. 2):

Fremgangsmåten er for å starte opp en brønn som har blitt stengt og skal startes igjen. The procedure is to start up a well that has been shut down and is to be started up again.

Apparatet (3) reduserer trykket nedstrøms (1) av brønnen, som ikke klarer å levere inn til produksjonsheader (P2) grunnet for lavt trykk (P1) i brønn. The device (3) reduces the pressure downstream (1) of the well, which fails to deliver to the production header (P2) due to low pressure (P1) in the well.

Apparatet vil hjelpe brønnen i gang og drifte den frem til den er «varm nok» til å selv pro-dusere. The device will help start the well and operate it until it is "hot enough" to produce itself.

Apparatet vil typisk bli brukt i en oppstartsfase etter en brønn har blitt stengt og skal startes igjen. The device will typically be used in a start-up phase after a well has been shut down and is to be started again.

Økt produksjon for brønner som trenger mindre mottrykk Increased production for wells that need less back pressure

Det bør bemerkes at alle de ovennevnte utførelsesformer illustrerer oppfinnelsen, men begrenser den ikke, og fagpersoner på området vil kunne utforme mange alternative utførelsesformer uten å avvike fra omfanget av de vedlagte kravene. I kravene skal referansenumre i parentes ikke sees som begrensende. Bruken av verbet "å omfatte" og dets ulike former, ekskluderer ikke tilstedeværelsen av elementer eller trinn som ikke er nevnt i kravene. De ubestemte artiklene "en", "ei" eller "et" foran et element ekskluderer ikke tilstedeværelsen av flere slike elementer. Det faktum at en-kelte trekk er anført i innbyrdes forskjellige avhengige krav, indikerer ikke at en kombinasjon av disse trekk ikke med fordel kan brukes. I apparatkrav som nevner flere midler, kan flere av disse midlene være omfattet i ett og samme element av maskinvaren. It should be noted that all of the above embodiments illustrate the invention, but do not limit it, and those skilled in the art will be able to devise many alternative embodiments without departing from the scope of the appended claims. In the requirements, reference numbers in brackets should not be seen as limiting. The use of the verb "to comprise" and its various forms does not exclude the presence of elements or steps not mentioned in the claims. The indefinite articles "an", "ei" or "et" before an element do not exclude the presence of several such elements. The fact that certain features are listed in mutually different dependent claims does not indicate that a combination of these features cannot be advantageously used. In device claims that mention several means, several of these means may be included in one and the same element of the hardware.
