Description
Foreliggende oppfinnelse angår stabile, ikke-vandige oppslemminger av vannoppløselige polymerer samt anvendelse derav. Mer spesielt er oppslemmingene kjennetegnet ved at de som medium har polyetylenglykol med lav molekylvekt, og som stabilisator et aminfosfatestersalt. The present invention relates to stable, non-aqueous slurries of water-soluble polymers and their use. More specifically, the slurries are characterized by the fact that they have low molecular weight polyethylene glycol as medium, and an amine phosphate ester salt as stabilizer.
Hydrofile polymerer eller harpikser finner vid anvendelse i industrien. De anvendes for å fortykke, suspendere eller stabilisere vandige systemer. Disse harpikser kan produsere geler eller virke som emulsjonsstabilisatorer, flokkule-ringsmidler, bindemidler, filmdannere, smøremidler eller midler for redusering av friksjon. Ved hver av disse anvendelser anvendes polymerene for å justere og kontrollere de reologiske egenskaper for det vandige system til hvilket de tilsettes. Hydrophilic polymers or resins are widely used in industry. They are used to thicken, suspend or stabilize aqueous systems. These resins can produce gels or act as emulsion stabilizers, flocculants, binders, film formers, lubricants or friction reducers. In each of these applications, the polymers are used to adjust and control the rheological properties of the aqueous system to which they are added.
For kommersielle og industrielle anvendelser er hurtig tilsetning av disse harpikser til vann i høy grad ønskelig. Når dette gjøres, resulterer det er imidlertid ofte i dannelse av klumper av uhydratisert polymer. Disse klumper er gel-lignende substanser, våte på yttersiden og tørre inne i, og de dannes som et resultat av at polymeren begynner å hydratisere før polymermolekylene er dispergert. Straks det ytre lag av polymeren er hydratisert, kan ikke klumpen eller fiskeøyet disper-geres selv ved kraftig blanding. Fjerning av disse klumper resulterer i betydelige tap av tid, materialer og polymereffektivitet. For commercial and industrial applications, rapid addition of these resins to water is highly desirable. When this is done, however, it often results in the formation of lumps of unhydrated polymer. These lumps are gel-like substances, wet on the outside and dry on the inside, and they form as a result of the polymer starting to hydrate before the polymer molecules are dispersed. As soon as the outer layer of the polymer is hydrated, the lump or fish eye cannot be dispersed even with vigorous mixing. Removal of these clumps results in significant losses of time, materials and polymer efficiency.
Disse klumper er spesielt problematiske i olje- og gassindustrien hvor vannoppløselige polymerer anvendes nede i hullet under borings-, brønnover-halings-, kompletterings-, stimulerings- og reservaroversvømmings-operasjoner. Disse ikke-hydratiserte klumper som er inerte mot enzymer, kjemiske nedbrytere og syrer, forårsaker forskjellige problemer inkludert gjenpluggig av brønnen og permeabilitetsforringelse i de oljebærende lag. These clumps are particularly problematic in the oil and gas industry where water-soluble polymers are used downhole during drilling, well overhaul, completion, stimulation and reservoir flooding operations. These non-hydrated lumps, which are inert to enzymes, chemical degraders and acids, cause various problems including plugging of the well and permeability degradation in the oil-bearing formations.
I tillegg - dersom polymerer anvendes - tilsettes de typisk til vann i en for-tynnet løsning. Under denne operasjon genereres ofte flyktig støv. Dette støv har mange skadelige virkninger. Støvet kan inhaleres av arbeidere som tilbereder løs-ningen. Noen av polymerene som kan suspenderes i et ikke-toksisk løsemiddel utvikler støv når de håndteres i pulverisert form, og dette kan føre til allergisk reaksjon og/eller irritasjon hos noen individer. Støv kan også bli ført til områder der det ikke er ment å være. In addition - if polymers are used - they are typically added to water in a diluted solution. During this operation, volatile dust is often generated. This dust has many harmful effects. The dust can be inhaled by workers preparing the solution. Some of the polymers that can be suspended in a non-toxic solvent develop dust when handled in powdered form, and this may cause an allergic reaction and/or irritation in some individuals. Dust can also be carried to areas where it is not meant to be.
For å unngå dannelse av klumper og støv og de problemer som følger med dette kan polymerene settes til det vandige system som flytende oppslemminger. Flere metoder for å gjennomføre dette, samt blandingene som derved fremstilles, er beskrevet i den kjente teknikk. Til forskjell fra foreliggende oppfinnelse anvendes det ofte oljebærere (f.eks. mineral- eller dieselolje) for å suspendere og levere polymerene til de vandige systemer. I tillegg til olje-bærerfluidet inneholder disse oppslemminger ofte leire eller leirlignende partikler som bidrar til å øke viskositeten og til å stabilisere den ikke-vandige suspensjon. Ulempene med disse bærersystemer er at forsøk på å eliminere oljen, som ofte er en uønsket komponent, resulterer i substitusjon av oljen med toksisk glykoleter. Leir-komponenten er som sådan også ofte en uønsket bestanddel. Dette er spesielt tilfelle ved anvendelser på olje- og gassfelt hvor inkorporering av leiren i oppslemmingene, noe som er nødvendig for å holde polymeren i løsning, for-ringer permeabiliteteten i de olje- og gassholdige sedimentlag. Dette er problemet som forårsakes av dannelse av fiskeøyne som oljeoppslemmingen forutsettes å skulle eliminere. To avoid the formation of lumps and dust and the problems that come with this, the polymers can be added to the aqueous system as liquid slurries. Several methods for carrying this out, as well as the mixtures produced thereby, are described in the known technique. In contrast to the present invention, oil carriers (eg mineral or diesel oil) are often used to suspend and deliver the polymers to the aqueous systems. In addition to the oil carrier fluid, these slurries often contain clay or clay-like particles which help to increase the viscosity and to stabilize the non-aqueous suspension. The disadvantages of these carrier systems are that attempts to eliminate the oil, which is often an undesirable component, result in the substitution of the oil with toxic glycol ether. As such, the clay component is also often an undesirable component. This is particularly the case in applications on oil and gas fields where incorporation of the clay in the slurries, which is necessary to keep the polymer in solution, reduces the permeability in the oil and gas containing sediment layers. This is the problem caused by the formation of fish eyes that the oil slurry is supposed to eliminate.

Denne komponent er reaksjonsproduktet av et amin med en fosfatester som har én eller flere hydrofobe grupper. Eksempler på fosfatestere som kan vel-ges som utgangsmaterialer inkluderer fosfatestere av alkoksylerte lineære alkoholer {etoksylerte og/eller propoksylerte) og fosfatestere av alkylfenoler. En spesielt foretrukket kommersielt tilgjengelig fosfatester omfatter poly(oksy-1,2-etandiyl),a-9-oktadecenyl-©-hydroksy-(Z)-fosfat. This component is the reaction product of an amine with a phosphate ester having one or more hydrophobic groups.

A particularly preferred commercially available phosphate ester comprises poly(oxy-1,2-ethanediyl),α-9-octadecenyl β-hydroxy-(Z)-phosphate.
Aminet som kan anvendes er hvilket som helst amin som er i stand til å reagere med fosfatesteren for å gi et aminsalt av esteren. Eksempler på slike aminer inkluderer 2-amino-2-metyl-1-propanol, trietanolamin, dietanolamin og andre mono-, di- og trialkylaminer eller aminalkoholer, idet 2-amino-2-metyl-1-propanol er spesielt foretrukket. The amine which can be used is any amine capable of reacting with the phosphate ester to give an amine salt of the ester. Examples of such amines include 2-amino-2-methyl-1-propanol, triethanolamine, diethanolamine and other mono-, di- and trialkylamines or amine alcohols, 2-amino-2-methyl-1-propanol being particularly preferred.
Aminfosfatestersaltet fremstilles ved å anbringe fosfatesteren i en beholder som inneholder et løsemiddel, fortrinnsvis polyalkylenglykolen som anvendes for å danne oppslemmingen ifølge foreliggende oppfinnelse. Deretter settes aminet til beholderen, fortrinnsvis ved omgivelsestemperatur eller ved en temperatur som ikke er høyere enn ca. 90°C, og innholdet blandes under agitering inntil det oppnås en ensartet flytende blanding. Den resulterende blanding kan lagres i flytende form ved omgivelsesbetingelser. The amine phosphate ester salt is prepared by placing the phosphate ester in a container containing a solvent, preferably the polyalkylene glycol used to form the slurry according to the present invention. The amine is then added to the container, preferably at ambient temperature or at a temperature not higher than approx. 90°C, and the contents are mixed with agitation until a uniform liquid mixture is obtained. The resulting mixture can be stored in liquid form at ambient conditions.
I tillegg til de tre komponenter kan oppslemmingene i henhold til foreliggende oppfinnelse omfatte de følgende valgfrie additivmaterialer: Proppemidler, antiskummidler, overflateaktive midler, korrosjonsinhibitorer, baktericider og lignende. In addition to the three components, the slurries according to the present invention can include the following optional additive materials: Stoppers, antifoam agents, surfactants, corrosion inhibitors, bactericides and the like.
For å produsere oppslemmingen ifølge foreliggende oppfinnelse blandes de tre kritiske komponenter og eventuelle additiver ganske enkelt sammen. I en foretrukket synteseprosedyre fremstilles først det stabiliserende aminfosfatestersalt, fortrinnsvis i et polyalkylenglykol-løsemiddel. Dersom aminfosfatestersaltet fremstilles i et løsemiddel annet enn en polyalkylenglykol, isoleres det ved hjelp av metoder som er kjent innenfor fagområdet (f.eks. filtrering, krystallisering, etc.) og blandes deretter inn i polyalkylenglykolen. To produce the slurry according to the present invention, the three critical components and any additives are simply mixed together. In a preferred synthesis procedure, the stabilizing amine phosphate ester salt is first prepared, preferably in a polyalkylene glycol solvent. If the amine phosphate ester salt is prepared in a solvent other than a polyalkylene glycol, it is isolated using methods known in the art (e.g. filtration, crystallization, etc.) and then mixed into the polyalkylene glycol.
Deretter settes den vannoppløselige polymer og eventuelle additiver til polyalkylenglykol-løsemidlet som inneholder aminfosfatestersalt-stabilisator og blandingen agiteres en stund med en agiteringsgrad som er nødvendig for å frem-stille en ensartet suspensjon. Slike betingelser bør være tilstrekkelige til å skape og opprettholde en virvel i reaksjonsbeholderen ved temperaturer lavere enn 90°C, fortrinnsvis ved omgivelsestemperaturer (dvs. 20 - 40°C). Den resulterende suspensjon kan pakkes og lagres ved omgivelsesbetingelser. The water-soluble polymer and any additives are then added to the polyalkylene glycol solvent containing the amine phosphate ester salt stabilizer and the mixture is agitated for a while with a degree of agitation necessary to produce a uniform suspension. Such conditions should be sufficient to create and maintain a vortex in the reaction vessel at temperatures lower than 90°C, preferably at ambient temperatures (ie 20 - 40°C). The resulting suspension can be packaged and stored at ambient conditions.
Oppslemmingene ifølge foreliggende oppfinnelse er ekstremt stabile, og de beholder sin stabilitet ved omgivelses-lagringsbetingelser - uten dannelse av klumper fra den vannoppløselige polymer - i mer enn tre måneder, mer fore trukket mer enn seks måneder og mest foretrukket mer enn tolv måneder. I tillegg kan oppslemmingene anvendes over et vidt temperaturområde, idet anvendelsesområder fra ca. -20°C til ca. 50°C anses å være innenfor rammen av foreliggende oppfinnelse. Videre anses oppslemmingene å være miljøvennlige, og de er biolo-gisk nedbrytbare. The slurries according to the present invention are extremely stable, and they retain their stability at ambient storage conditions - without formation of lumps from the water-soluble polymer - for more than three months, more preferably more than six months and most preferably more than twelve months. In addition, the slurries can be used over a wide temperature range, as application areas from approx. -20°C to approx. 50°C is considered to be within the scope of the present invention. Furthermore, the slurries are considered to be environmentally friendly, and they are biologically degradable.
Oppslemmingene ifølge foreliggende oppfinnelse kan anvendes for hvilket som helst kommersielt formål hvor tørre vannoppløselige polymerer tidligere er blitt anvendt, samt for formål hvor tørre vannoppløselige polymerer ikke har vært godt egnet på grunn av deres langsomme oppløsningshastigheter. Oppslemmingene er spesielt nyttige for anvendelser som involverer dispergering av de vann-oppløselige polymerer i vandige løsninger. Inkludert blant slike anvendelser er de følgende: Miljøformål (f.eks. avhjelpende tiltak), papiranvendelser, jordbruksan-vendelser, tekstilanvendelser og oljefelt-anvendelser. The slurries according to the present invention can be used for any commercial purpose where dry water-soluble polymers have previously been used, as well as for purposes where dry water-soluble polymers have not been well suited due to their slow dissolution rates. The slurries are particularly useful for applications involving the dispersion of the water-soluble polymers in aqueous solutions. Included among such applications are the following: Environmental purposes (eg remedial measures), paper applications, agricultural applications, textile applications and oil field applications.
Spesifikke anvendelser for oppslemmingene ifølge foreliggende oppfinnelse er som følger: I papirindustrien kan oppslemmingene anvendes som drene-rings- og retensjonshjelpemidler, ved klaring av bakvann, som våt- og tørrstyrke-harpikser og som slippmidler. Specific applications for the slurries according to the present invention are as follows: In the paper industry, the slurries can be used as drainage and retention aids, when clarifying backwater, as wet and dry strength resins and as release agents.
I tekstilindustrien kan oppslemmingene anvendes for trykking på og farging av tepper hvor det er tvingende nødvendig at den vannoppløselige polymer ikke inneholder klumper når den belegges på stoffer ettersom slike klumper kan redu-sere verdien av teppet fra førsteklasses til annenklasses. Oppslemmingene kan også anvendes som stabilisatorer for skummende baksider av teppene. In the textile industry, the slurries can be used for printing on and dyeing carpets where it is absolutely necessary that the water-soluble polymer does not contain lumps when it is coated on fabrics, as such lumps can reduce the value of the carpet from first-class to second-class. The slurries can also be used as stabilizers for foaming backs of the carpets.
I petroleumsindustrien kan de vannoppløselige polymerer i henhold til foreliggende oppfinnelsen anvendes for å senke pumpefriksjonen, for å heve den lave skjærkraftviskositeten slik at fluidtapet til de omgivende lag reguleres, og for å skyve oljen til pumpebrønnen. Polymerene anvendes også i boreslam, kompletterings- og overhalingsfluider, surgjørings- og fraktureringsfluider, i barrierefluider for å regulere vann/olje-forholdet og i polymer-overfyllingsoperasjoner. Anvendelsen av disse polymerer i overfyllingsoperasjoner blir viktigere etterhvert som pri-sen på råolje fortsetter å stige og tilgjengeligheten fortsetter å synke. Anvendelsen av disse polymerer bak et micelle-fluid gjør at oljeprodusenten kan oppnå en tredje utvinning av olje fra disse feltene. In the petroleum industry, the water-soluble polymers according to the present invention can be used to lower the pump friction, to raise the low shear viscosity so that the fluid loss to the surrounding layers is regulated, and to push the oil to the pump well. The polymers are also used in drilling mud, completion and overhaul fluids, acidizing and fracturing fluids, in barrier fluids to regulate the water/oil ratio and in polymer overflow operations. The use of these polymers in overfilling operations becomes more important as the price of crude oil continues to rise and availability continues to decrease. The use of these polymers behind a micelle fluid enables the oil producer to achieve a third extraction of oil from these fields.

Oppfinnelsen beskrives mer detaljert ved hjelp av de følgende ikke-begren-sende eksempler. The invention is described in more detail by means of the following non-limiting examples.
Eksempel 1 Example 1
(1) Fremstilling av stabilisator (1) Preparation of stabilizer
Til 100 deler polyetylenglykoi (molekylvekt = 200) tilsettes det ved 25-50°C 6,82 deler poly(oksy-1-2-etandiyl),a-9-oktadecenyl-<a-hydroksy-(Z)-fosfat. Reaksjonsbeholderen agiteres ved 200 omdr./min. ved en temperatur på 25-50°C i 15 minutter. 0,91 deler 2-amino-2-metyl-1-propanol tilsettes, og innholdet i beholderen blandes ved 200 omdr./min. ved en temperatur på 25-50°C i 15 minutter, for å få en jevn blanding. Den resulterende blanding inneholder ca. 7,73 vektprosent av blandingen av 2-amino-2-metyl-1-propanolsaltet av poly(oksy-1,2-etandiyl),a-9-oktadecenyl-co-hydroksy-(Z)-fosfat. To 100 parts of polyethylene glycol (molecular weight = 200), 6.82 parts of poly(oxy-1-2-ethanediyl),α-9-octadecenyl-<α-hydroxy-(Z)-phosphate are added at 25-50°C. The reaction container is agitated at 200 rpm. at a temperature of 25-50°C for 15 minutes. 0.91 parts of 2-amino-2-methyl-1-propanol are added, and the contents of the container are mixed at 200 rpm. at a temperature of 25-50°C for 15 minutes, to obtain a uniform mixture. The resulting mixture contains approx. 7.73% by weight of the mixture of the 2-amino-2-methyl-1-propanol salt of poly(oxy-1,2-ethanediyl),α-9-octadecenyl-co-hydroxy-(Z)-phosphate.
(2) Fremstilling av oppslemning (2) Preparation of slurry
71,9 deler xantanharpiks settes til blandingen som omfatter 7,73 deler stabilisator og 100 deler polyetylenglykoi (molekylvekt = 200). Reaksjonsbeholderen agiteres ved 650 omdr./min. ved en temperatur på 25°C i 60 minutter inntil det oppnås en jevn suspensjon. Den resulterende blanding inneholder ca. 45,0 vektprosent av xantanharpiks-suspensjonen. Viskositeten for væsken er 8000 eps som målt ved hjelp av et Brookfield RVF-viskosimeter, spindel nr. 4, 20 omdr./min. Oppslemmingen vedblir å være en stabil væske ved lagrings-temperaturer helt ned til -20°C og helt opp til 50°C og i lagringsperioder som overstiger ett år. 71.9 parts xanthan resin is added to the mixture comprising 7.73 parts stabilizer and 100 parts polyethylene glycol (molecular weight = 200). The reaction container is agitated at 650 rpm. at a temperature of 25°C for 60 minutes until a uniform suspension is obtained. The resulting mixture contains approx. 45.0% by weight of the xanthan resin suspension. The viscosity of the liquid is 8000 eps as measured using a Brookfield RVF viscometer, #4 spindle, 20 rpm. The slurry remains a stable liquid at storage temperatures as low as -20°C and as high as 50°C and for storage periods exceeding one year.
Oppslemmingen kan anvendes på områder som drøftet tidligere i denne søknad og mer spesielt ved fordeling i vandig miljø. Xantanharpiksen gjennom-fordeles i det vandige miljø på en kontinuerlig måte uten dannelse av klumper. Dersom xantanpulver sammenligningsvis tilsettes alene til et vandig miljø i fast form, vil det danne seg mange klumper og den resulterende suspensjon vil ikke være kontinuerlig. Anvendelsen av den flytende ikke-vandige oppslemming i henhold til oppfinnelsen kan følgelig være gunstigere for fordelingen av xantan i vandig miljø enn en metode som fordeler xantanharpiksen i fast, pulverisert form. The slurry can be used in areas discussed earlier in this application and more particularly when distributed in an aqueous environment. The xanthan resin is distributed throughout the aqueous environment in a continuous manner without the formation of lumps. If, by comparison, xanthan powder is added alone to an aqueous environment in solid form, many lumps will form and the resulting suspension will not be continuous. The use of the liquid non-aqueous slurry according to the invention may consequently be more favorable for the distribution of xanthan in an aqueous environment than a method that distributes the xanthan resin in solid, powdered form.
Etter å ha gitt en detaljert beskrivelse av oppfinnelsen og med referanse til de foretrukne utførelser derav, vil det være klart at modifikasjoner og variasjoner er mulige uten å komme bort fra rammen av de vedlagte krav. Having given a detailed description of the invention and with reference to the preferred embodiments thereof, it will be clear that modifications and variations are possible without departing from the scope of the appended claims.
