Description
Foreliggende oppfinnelse vedrører vandige oppløsninger og/eller dispersjoner av polymerer som er stabilisert med spesielle produkter, fremstilling derav ved blanding av polymerer, vann og eventuelt ytterligere tilsatsstoffer som f.eks. beskrevet i G.R. Gray, "Composition of Drilling Fluids", fjerde utgave 1980, side 526-586, med det spesielle produktet, samt anvendelse derav ved utvinning av jordolje. The present invention relates to aqueous solutions and/or dispersions of polymers that have been stabilized with special products, production thereof by mixing polymers, water and possibly further additives such as e.g. described in G.R. Gray, "Composition of Drilling Fluids", fourth edition 1980, pages 526-586, with the particular product, as well as its application in the extraction of petroleum.
Et anvendelsesområde for vandige oppløsninger og/eller dispersjoner av polymerer ved utvinningen av jordolje er tilveiebringelse og behandling av borehull. Eventuelt kan man tilføre slike oppløsninger og/eller dispersjoner bestemte egenskaper ved tilsats av additiver, f.eks. når det gjelder deres rheologiske oppførsel, deres viskositet, gelstyrke, suspen-sjonsevne for faste tilsatser og reduksjon av vanntapet ved filtrering i porøse formasjoner. Tilsvarende innstilte oppløsninger og/eller dispersjoner kan eksempelvis anvendes som spylevæske, spesielt som vannbasisk dypborespylevæske, "Frac"-væske eller overhalingsvæske. An area of application for aqueous solutions and/or dispersions of polymers in the extraction of petroleum is the provision and treatment of boreholes. Optionally, such solutions and/or dispersions can be given specific properties by adding additives, e.g. in terms of their rheological behaviour, their viscosity, gel strength, suspension capacity for solid additives and reduction of water loss by filtration in porous formations. Correspondingly adjusted solutions and/or dispersions can, for example, be used as flushing fluid, especially as water-based deep drilling flushing fluid, "Frac" fluid or overhaul fluid.
Som polymerer anvendes generelt cellulosederivater, polysakkarider og/eller guargummi. Disse utsettes imidlertid ved de anvendelses-betingelsene som finnes i borehullene lett for en termisk nedbrytning som påvirker egenskapene for oppløsningene og/eller dispersjonene i negativ retning. Slike egenskapsendringer, f.eks. viskositetsreduksjoner, opptrer ved spylevæsker som inneholder hydroksyetylcellulose allerede ved temperaturer fra ca. 80 "C, ved spylevæsker som inneholder karboksymetylcellulose eller xanthan ved temperaturer fra ca. 100 °C. Ved slike væsker er det derfor påkrevet løpende å etterdosere polymerer for å opprettholde egenskapsbildet for oppløsningen og/eller dispersjonen over lengere tid. As polymers, cellulose derivatives, polysaccharides and/or guar gum are generally used. However, under the conditions of use found in the boreholes, these are easily exposed to a thermal breakdown which affects the properties of the solutions and/or dispersions in a negative direction. Such property changes, e.g. viscosity reductions, occur with flushing fluids containing hydroxyethyl cellulose already at temperatures from approx. 80 "C, for flushing liquids containing carboxymethyl cellulose or xanthan at temperatures from about 100 °C. With such liquids, it is therefore required to continually add polymers to maintain the properties of the solution and/or dispersion over a longer period of time.
Det har allerede vært foreslått å forbedre temperaturbestandigheten for vandige polysakkarid-oppløsninger ved hjelp av bestemte tilsatser. It has already been proposed to improve the temperature resistance of aqueous polysaccharide solutions by means of certain additives.
Ifølge DE-OS 2 715 026 skal en tilsats bestående av en kombinasjon av en svovelholdig anti-oksydant og en lett oksyderbar alkohol være virksom. Forsøkene ble gjennomført ved 97° C. For høyere temepraturer og alkaliske omgivelser, slik de forekommer ved dypboring, er slike stabili satorer imidlertid ikke brukbare idet svovelforbindelsene nedbrytes og alkoholene langsomt frigjøres. According to DE-OS 2 715 026, an additive consisting of a combination of a sulfur-containing antioxidant and an easily oxidizable alcohol should be effective. The experiments were carried out at 97° C. However, for higher temperatures and alkaline environments, such as occur in deep drilling, such stabilizers are not usable as the sulfur compounds break down and the alcohols are slowly released.
I US-PS 3 953 335 foreslås magnesiumoksyd som tilsats til borevæsker som ikke inneholder leire. Ved siden av denne begrensede anvende-ligheten for magnesiumoksyd-tilsatsen oppnås også her bare en begrenset temepraturstabilitet. In US-PS 3,953,335, magnesium oxide is proposed as an additive to drilling fluids that do not contain clay. In addition to this limited applicability of the magnesium oxide additive, only a limited temperature stability is achieved here as well.
I SU-PS'ene 402 633, 730 786 og 1 039 949 foreslås mono-, di- og trietanolamin, samt komplekse blandinger som enten inneholder etanol, amin og urinstoff, eller fenol, urinstoff og leire, eller boraks, etanolamin, urinstoff og etanol, eller talloljedestillater og komplekse trietanolamin-etere som stabilisatorer. Den stabiliserende virkningen av disse addi-tivene er imidlertid liten (se eksempel 8). I tillegg er de anvendte tilsatsene relativt dyre og, når det gjelder komplekse blandinger, omstendelige og uøkonomiske på grunn av kompliserte og tallrike doseringer. In the SU-PSs 402 633, 730 786 and 1 039 949, mono-, di- and triethanolamine are proposed, as well as complex mixtures that either contain ethanol, amine and urea, or phenol, urea and clay, or borax, ethanolamine, urea and ethanol, or tall oil distillates and complex triethanolamine ethers as stabilizers. However, the stabilizing effect of these additives is small (see example 8). In addition, the additives used are relatively expensive and, in the case of complex mixtures, cumbersome and uneconomical due to complicated and numerous dosages.
Det består følgelig fremdeles et behov for en enkel, billig og likevel godt virksom stabilisator for vandige polymeroppløsninger og/eller-dispe r sjoner. Consequently, there is still a need for a simple, cheap and yet effective stabilizer for aqueous polymer solutions and/or dispersions.
Det er nå funnet stabiliserte vandige polymeroppløsninger og/eller-dispersjoner som er kjennetegnet ved at de inneholder et produkt som kan oppnås ved at man på i og for seg kjent måte omsetter alkanolaminer med ammoniakk i nærvær av hydrogen og katalysatorer til diaminer, og deretter fra reaksjonsblandingen fradestillerer ikke omsatte utgangsmaterialer, vann og det dannede diaminet. Stabilized aqueous polymer solutions and/or dispersions have now been found which are characterized by the fact that they contain a product which can be obtained by reacting alkanolamines with ammonia in the presence of hydrogen and catalysts to diamines in a manner known per se, and then from the reaction mixture does not distill off reacted starting materials, water and the diamine formed.
Fremstillingen av diaminer fra alkanolaminer med ammoniakk i nærvær av hydrogen og katalysatorer er kjent (se f.eks. Ullmann's "Enzyklopådie der technischen Chemie", 4. opplag, bind VII, side 380-383 (1974), DE-AS 1 172 268 og US-PS 2 861 995). The preparation of diamines from alkanolamines with ammonia in the presence of hydrogen and catalysts is known (see e.g. Ullmann's "Enzyklopådie der technischen Chemie", 4th edition, volume VII, pages 380-383 (1974), DE-AS 1 172 268 and US-PS 2,861,995).
Herved kan alkanolaminer med eksempelvis 2-10 C-atomer, som etanolamin, isopropanolamin, 1,4-butanolamin, 1,6-heksanolamin eller 1,8-oktanolamin omsettes med overskudd av ammoniakk, eksempelvis 3 til 150 mol ammoniakk/mol alkanolamin, i nærvær av hydrogen, eksempelvis 5 til 100 liter hydrogen/mol alkanolamin i nærvær av katalysatorer, eksempelvis hydreringskatalysatorer som inneholder kobolt, nikkel, kobber, sølv, mangan, jern, platina og/eller palladium i elementær form, eller i form av hydrogenforbindelser eller " kromitt, ved forhøyet temperatur, eksempelvis ved 150 til 300°C og forhøyet trykk, eksempelvis ved 10 til 500 bar. Fra de slik oppnådde reaksjonsblandingene fraskilles uomsatt ammoniakk generelt ved trykkavlastning, dannet diamin og vann ved destillasjon ved normaltrykk eller svakt redusert trykk, eksempelvis ved 1 til 0,1 bar, og uomsatt alkanolamin ved destillasjon ved svakt eller sterkt redusert trykk, eksempelvis ved 500 til 10 mbar. Herved forblir en destillasjonsrest som man idag ikke kjenner noen teknisk anvendelsesmulighet for. Denne samles derfor i depoter og forbrennes ved høye temperaturer. In this way, alkanolamines with, for example, 2-10 C atoms, such as ethanolamine, isopropanolamine, 1,4-butanolamine, 1,6-hexanolamine or 1,8-octanolamine can be reacted with an excess of ammonia, for example 3 to 150 mol ammonia/mol alkanolamine, in the presence of hydrogen, for example 5 to 100 liters of hydrogen/mol of alkanolamine in the presence of catalysts, for example hydrogenation catalysts containing cobalt, nickel, copper, silver, manganese, iron, platinum and/or palladium in elemental form, or in the form of hydrogen compounds or " chromite, at elevated temperature, for example at 150 to 300°C and elevated pressure, for example at 10 to 500 bar. From the reaction mixtures thus obtained, unreacted ammonia is generally separated by pressure relief, formed diamine and water by distillation at normal pressure or slightly reduced pressure, for example at 1 to 0.1 bar, and unreacted alkanolamine by distillation at slightly or strongly reduced pressure, for example at 500 to 10 mbar. This leaves a distillation residue for which no technical application possibility is currently known. This is therefore collected in depots and incinerated at high temperatures.
Idet en rekke diaminer fremstilles i stor teknisk skala ved den ovenfor omtalte fremgangsmåten, f.eks. etylendiamin, 1,2-propylendiamin og 1,6-heksametylendiamin, oppstår det store mengder av slike destillasjonsrester, som nå innenfor rammen av foreliggende oppfinnelse kan finne en teknisk anvendelse. Since a number of diamines are produced on a large technical scale by the above-mentioned method, e.g. ethylenediamine, 1,2-propylenediamine and 1,6-hexamethylenediamine, large quantities of such distillation residues occur, which can now find a technical application within the scope of the present invention.

Fortrinnsvis utgjør dette innholdet 0,1 till,0 vekt-%. The stabilized aqueous polymer solutions and/or dispersions according to the invention may contain distillation residues of the type mentioned above, for example in amounts from 0.001 to 3.0% by weight. Preferably, this content amounts to 0.1 to 0.0% by weight.
Fortrinnsvis inneholder de stabiliserte vandige polymeroppløsningene og/eller -dispersjonene ifølge oppfinnelsen destillasjonsrester fra fremstillingen av etylendiamin eller 1,2-propylendiamin ved katalyttisk aminering av etanolamin eller isopropanolamin. Preferably, the stabilized aqueous polymer solutions and/or dispersions according to the invention contain distillation residues from the production of ethylenediamine or 1,2-propylenediamine by catalytic amination of ethanolamine or isopropanolamine.
De øvrige bestanddelene i de stabiliserte vandige polymeroppløsningene og/eller -dispersjonene ifølge oppfinnelsen kan tilsvare teknikkens stand. Eksempelvis kan de som polymerer inneholde cellulosederivater, som hydroksyetylcellulose og karboksymetylcellulose, polysakkarider som xanthan og stivelser, eller guargummi, eksempelvis i mengder fr a0,01 til 5,0 vekt-%. The other components in the stabilized aqueous polymer solutions and/or dispersions according to the invention may correspond to the state of the art. For example, the polymers may contain cellulose derivatives, such as hydroxyethyl cellulose and carboxymethyl cellulose, polysaccharides such as xanthan and starches, or guar gum, for example in amounts from 0.01 to 5.0% by weight.
Ved de stabiliserte vandige polymeroppløsningene og/eller -dispersjonene ifølge oppfinnelsen kan det inneholdte vannet være av en hvilken som helst type. Eksempelvis kan det dreie seg om drikkevann, spillvann, overflatevann, og/eller sjøvann og/eller innsjøvann. In the case of the stabilized aqueous polymer solutions and/or dispersions according to the invention, the contained water can be of any type. For example, it could be drinking water, waste water, surface water, and/or sea water and/or lake water.
Videre kan også ytterligere tilsatser være tilstede, eksempelvis 0-10 vekt-% leire som bentonitt eller attapulgitt; 0-10 vekt-% borepartikler eller utborede leirer; 0-30 vekt-% baritt, ilmenitt eller jernoksyd; 0-30 vekt-% sand eller såkalte "proppants" som boksitt; salter som kaliumklorid, natriumklorid, kalsiumklorid osv. i en mengde på 0-40 vekt-%; videre glidemiddel, korrosjonsbeskyttelsesadditiver og baktericider, f.eks. sulfitter eller kvarternære ammoniumforbindelser og videre additiver som vanligvis anvendes i borehull-spylevæsker, overhalingsvæsker og "frac"-væsker. Furthermore, further additives can also be present, for example 0-10% by weight of clay such as bentonite or attapulgite; 0-10% by weight drilling particles or drilled clays; 0-30% by weight of barite, ilmenite or iron oxide; 0-30% by weight sand or so-called "proppants" such as bauxite; salts such as potassium chloride, sodium chloride, calcium chloride, etc. in an amount of 0-40% by weight; further lubricants, corrosion protection additives and bactericides, e.g. sulphites or quaternary ammonium compounds and further additives which are usually used in borehole flushing fluids, overhaul fluids and "frac" fluids.

De stabiliserte vandige polymeroppløsningene og/eller -dispersjonene ifølge oppfinnelsen er som regel stabile til ca. 160"C og høyere.

12,5 g handelsvanlig xanthan ble fordelt i 1000 g sjøvann (ifølge DIN 50900) under omrøring. Detter en svelletid på 16 timer ved romtemperatur ble viskositeten for oppløsningen målt i et Brookfield viskosimeter av type "LVTD" ved 60 opm. 12.5 g of commercial xanthan was distributed in 1000 g of seawater (according to DIN 50900) while stirring. After a swelling time of 16 hours at room temperature, the viscosity of the solution was measured in a Brookfield viscometer of the "LVTD" type at 60 rpm.
Deretter ble oppløsningen delt i fire like deler. Til tre deler ble det tilsatt 1,0 vekt-% av den ifølge eksempel 1 oppnådde destillasjonsresten, til den fjerde delen ble det tilsatt 1,0 vekt-% vann.

Til påvisning av den overlegne stabilisatorvirkningen som oppnås ved destillasjonsrestene som anvendes ifølge oppfinnelsen sammenlignet med de i SU 1039 949 A omtalte stabilisatorblandingene ble følgende forsøk gjennomført: 18,75 g handelsvanlig xanthan ble fordelt i 1500 g syntetisk sjøvann (ifølge DIN 50900) under omrøring. Etter en svelletid på 16 timer ved romtemperatur ble oppløsningen delt i seks like deler. To demonstrate the superior stabilizer effect achieved by the distillation residues used according to the invention compared to the stabilizer mixtures mentioned in SU 1039 949 A, the following experiment was carried out: 18.75 g of commercial xanthan was distributed in 1500 g of synthetic seawater (according to DIN 50900) while stirring. After a swelling time of 16 hours at room temperature, the solution was divided into six equal parts.
Til to prøver ble det tilsatt 1 vekt-% sjøvann. To andre prøver ble blandet med 1,0 vekt-% av den ifølge eksempel 1 oppnådde destillasjonsresten. 1% by weight of seawater was added to two samples. Two other samples were mixed with 1.0% by weight of the distillation residue obtained according to example 1.
De siste to prøvene ble blandet med 1,0 vekt-% av en blanding av 50 vekt-% talloljedestillat og 50 vekt-% trietanolamin-tris-glykoleter. The last two samples were mixed with 1.0% by weight of a mixture of 50% by weight tall oil distillate and 50% by weight triethanolamine-tris-glycol ether.
Deretter ble viskositeten for oppløsningene målt og de seks prøvene ble eldet i stålbomber ved 140 °C. Etter 48 timer og etter 75 timer ble det tatt ut tre bomber, disse ble avkjølt og viskositeten for innholdet ble målt. Then the viscosity of the solutions was measured and the six samples were aged in steel bombs at 140 °C. After 48 hours and after 75 hours, three bombs were taken out, these were cooled and the viscosity of the contents was measured.
Resultatene i tabell 4 viser at det virkelig oppnås en stabilisering ved tilsatsen av destillasjonsresten ifølge eksempel 1. The results in table 4 show that a stabilization is indeed achieved by the addition of the distillation residue according to example 1.
