Abstract

The insulating element is intended for use in external wall claddings of underground storeys or basements and comprises a plate formed from non-biodegradable and foamed plastic. Besides having a heat-insulating effect, the plate also assumes a draining function. In order to provide for this, the plate body 1, on the side facing the wall, has drainage recesses in the form of vertical grooves 2. The openings 3 of the drainage recesses and grooves 2 respectively are shielded in a liquid-permeable manner with a filter strip 6 made of non- woven fabric. The plate body 1 consists of extruded foamed plastic without plastic particle interspaces. <IMAGE>

Description

Leirspylinger på vannbasis. Water-based clay washes.

Oppfinnelsens gjenstand er en forbedret borespyling til nedføring av olje- og gassboringer. The object of the invention is an improved drill flushing for lowering oil and gas wells.

Ved boring av dypboringer anvendes normalt en spylevæske på vannbasis. Denne væske som pumpes inn i borestangen og igjen stiger opp mellom stangen og borhullveggen har å oppfylle flere funksjoner. Den virker som avkjølende og smørende medium for meiselen, kompenserer dannede trykk, fungerer som transportmiddel for det utborede gods pg frembringer et avtettende sjikt på den åpne borhullvegg. When drilling deep boreholes, a water-based flushing fluid is normally used. This liquid, which is pumped into the drill rod and again rises between the rod and the borehole wall, has several functions to fulfill. It acts as a cooling and lubricating medium for the chisel, compensates pressures, acts as a means of transport for the excavated material because it produces a sealing layer on the open borehole wall.

Vanligvis består slike væsker av en vandig suspensjon av svellende eller hydratiserbar leire, som f.eks. bentonitt, eller slike leirer, resp. finfordelte materialer som dannes under borings- Typically, such fluids consist of an aqueous suspension of swelling or hydratable clay, such as bentonite, or similar clays, resp. finely divided materials formed during drilling

forløpet. Dertil tilsettes andre stoffer, f.eks. tyngdemidler for the course. Other substances are added to it, e.g. gravity means for

å kompensere dannede høye trykk, organiske kolloider som f.eks. karboksy-metylcellulose, lawiskos stivelse, polyakrylater o.l. som skal understøtte dannelsen av avtettende sjikt på veggen. Disse for-holdsregler blir nødvendig når infiltrasjonen av ukontrollerbare vannmengder må unngås i borhullets omgivelser (regulering av vanntapet). Fordi spylingene skal ha den funksjon å transportere ut-horet gods oppad er det nødvendig at væsken har en bestemt strømnings-karakter. to compensate formed high pressures, organic colloids such as e.g. carboxymethylcellulose, Lawiskos starch, polyacrylates etc. which will support the formation of a sealing layer on the wall. These precautions become necessary when the infiltration of uncontrollable amounts of water must be avoided in the surroundings of the borehole (regulation of water loss). Because the flushing must have the function of transporting the discharged material upwards, it is necessary that the liquid has a specific flow character.

Viskositeten skal være høy nok til å transportere bor-subb, imidlertid på den annen side ikké så høy at det oppstår trykk-vanskeligheter i pumpesystemet. Samtidig kreves at borespylingens geleringstendens som oppstår i hviletilstand hindrer en avsetning av boreslam, f.eks. når væskens sirkulasjon av en eller annen grunn må avbrytes. Også denne karakteristiske størrelse av flyteforholdet (gelstyrke) må kunne styres således at ved gjenopptagning av sirku-lasjonen inntrer ingen pumpevanskeligheter. The viscosity must be high enough to transport boron-sub, however, on the other hand, not so high that pressure difficulties arise in the pumping system. At the same time, it is required that the gelling tendency of the drilling fluid which occurs in a state of rest prevents a deposit of drilling mud, e.g. when the fluid's circulation must be interrupted for one reason or another. This characteristic size of the flow ratio (gel strength) must also be able to be controlled so that no pumping difficulties occur when circulation is resumed.

For styring av flyteegenskapene og dermed borespylingens konsistens anvendes forskjellige kjemikalier - generelt betegnet som flytendegjørere - som f.eks. polyfosfater, tannater, humater eller lignosulfonater. Av disse har lignosulfonatene som er modifisert delvis med krom under oksydasjon innført seg i praksis og delvis fortrengt polyfosfater, tannater og humater. Enskjønt disse således fremstilte lignosulfonater, såkalte kromlignosulfonater også betegnet som (ferro)-kromlignosulfonater og de spylevellinger som inneholder disse ikke er så følsomme overfør elektrolyttforurensninger, som polyfosfat-, tannat- eller humatholdige systemer, kan det ved økende elektrolyttbeskadigelse, slik de forårsakes ved praktisk boring ved opptak av natriumklorid og/eller kalsiumsulfat ikke sees bort fra medanvendelsen av organiske beskyttelseskollolder for regulering av vanntapet. Tvangsmessig økes ved tilsetningen av slike kolloide stoffer spylevæskens viskositet, en effekt som løper sammen med virkningen av flytendegjørere. Humater, som ansees som virksomme bestanddeler av jordkull (lignitter) er ifølge deres struktur høy-molekylære og har kolloidal karakter. Deres flytendegjørende virk-ning er riktignok kjent, imidlertid kunne de ikke samtidig overta funksjonen av et beskyttelseskolloid da de selv er meget følsomme overfor elektrolyter. To control the flow properties and thus the consistency of the drilling fluid, various chemicals - generally referred to as liquefiers - are used, such as e.g. polyphosphates, tannates, humates or lignosulfonates. Of these, the lignosulphonates, which are partially modified with chromium during oxidation, have been introduced in practice and have partially displaced polyphosphates, tannates and humates. Although these lignosulfonates produced in this way, so-called chromium lignosulfonates also referred to as (ferro)-chromium lignosulfonates and the flushing solutions containing these are not so sensitive to electrolyte contamination, such as polyphosphate, tannate or humate-containing systems, increasing electrolyte damage, such as is caused by practical drilling when absorbing sodium chloride and/or calcium sulphate is not disregarded from the co-use of organic protective carbons for regulating the water loss. Inevitably, the addition of such colloidal substances increases the viscosity of the flushing liquid, an effect which runs together with the effect of liquefiers. Humates, which are considered to be active constituents of coal (lignites), are, according to their structure, high-molecular and have a colloidal character. Their liquefying effect is certainly known, however, they could not simultaneously take over the function of a protective colloid as they themselves are very sensitive to electrolytes.

Den erkjennelse, at ved kombinert anvendelse av lignosulfonater og humater - betinget ved en synergistisk effekt - gjør det mulig å oppnå en tilstrekkelig kontroll av de rheologiske egenskaper og også av vanntapet av et spylesystem, er et stort fremskritt. The realization that the combined use of lignosulfonates and humates - conditional on a synergistic effect - makes it possible to achieve a sufficient control of the rheological properties and also of the water loss of a flushing system, is a great advance.

Det er videre kjent å behandle lignit med kromat eller dikromat og å anvende de herav resulterende produkter, såkalt kromlignit, i kombinasjon med kromlignosulfonat. It is also known to treat lignite with chromate or dichromate and to use the resulting products, so-called chrome lignite, in combination with chrome lignosulfonate.

Ifølge foreliggende oppfinnelse oppnås forbedringen av de i og for seg kjente lignosulfonater resp. de i og for seg kjente humater, for det meste kalt lignitter ved at det i molekylet inn-føres kobolt som kation. Fremgangsmåten til fremstilling av slike forbindelser skal beskrives kort: According to the present invention, the improvement of the per se known lignosulfonates or the known humates in and of themselves, mostly called lignites because cobalt is introduced into the molecule as a cation. The procedure for the production of such compounds shall be briefly described:

a) Lignosulfonater. a) Lignosulfonates.

Den i cellulosefabrikker dannede sulfitavlut - den It in cellulose factories formed sulphite liquor - the

består i det vesentlige av en vandig oppløsning av kalsiumlignin-sulfonat - omsettes med et vannoppløselig koboltsalt, hvis anion med kalsium danner et i vann tungt oppløselig salt, fortrinnsvis kobolt-sulfat. Det ved denne dobbelte omsetning utfelte kalsiumsulfat fjernes ved filtrering, den vandige oppløsning av koboltligninsulfonat inndampes og forstøves. essentially consists of an aqueous solution of calcium lignin sulphonate - is reacted with a water-soluble cobalt salt, the anion of which with calcium forms a poorly water-soluble salt, preferably cobalt sulphate. The calcium sulfate precipitated by this double reaction is removed by filtration, the aqueous solution of cobalt lignin sulfonate is evaporated and atomized.

Ved siden av kobolt kan slike lignosulfonater også inneholde andre tungmetaller, f.eks. nikkel, kobber og fortrinnsvis jern. Koboltinnholdet skal herved, beregnet som CoO, utgjøre ca. In addition to cobalt, such lignosulfonates may also contain other heavy metals, e.g. nickel, copper and preferably iron. The cobalt content, calculated as CoO, should therefore amount to approx.

0,3 til 2,5 vektprosent,'fortrinnsvis 0,8 til 1,3 vektprosent, mens innholdet av andre tungmetaller likeledes beregnet som oksyd kan utgjøre inntil ca. 5 vektprosent, imidlertid skal det fortrinnsvis ligge under 3 vektprosent. 0.3 to 2.5 percent by weight, preferably 0.8 to 1.3 percent by weight, while the content of other heavy metals likewise calculated as oxide can amount to approx. 5 percent by weight, however, it should preferably be below 3 percent by weight.

b) Ligniter. b) Lignites.

Den på bergmannsvis fremstilte jordfarge, et fortrinn The earthy color produced in Bergmann's style, an advantage

til brunkull, behandles i vandig medium med et oppløselig koboltsalt. Etter avslutning av den herved foregående reaksjon behandles blandingen med en tilstrekkelig mengde alkalimetallhydroksyd, således at oppslemningen når en pH-verdi på minst 9. Det etter tørkning foreliggende produkt betegnes i det følgende med kobolt-lignit. to lignite, is treated in an aqueous medium with a soluble cobalt salt. After completion of the foregoing reaction, the mixture is treated with a sufficient amount of alkali metal hydroxide, so that the slurry reaches a pH value of at least 9. The product present after drying is hereinafter referred to as cobalt lignite.

Det ble nå funnet at styringen av filtreringsegen-skapene og flyteegenskapene av borspylinger begunstiges i uventet grad når det i leirspylinger på vannbasis kommer til anvendelse en kombinasjon av de ovenfor nevnte koboltforbindelser, dvs. av kobolt-(ferro)-lignosulfonat og kobolt-lignit. De anvendte mengder i leir-spylingen ligger ved kobolt-ligninsulfonat mellom 5 og 50 kg, fortrinnsvis 15 til 25 kg, ved kobolt-lignit mellom 2 og 50 kg» hver gang beregnet pr. spylevæske. Vektsforholdet mellom kobolt-ligninsulfonat og koboltlignit, skal fortrinnsvis velges således at det på 1 del kobolt-lignit kommer 1 til 4 deler kobolt-ligninsulfonat. It was now found that the control of the filtration properties and the flow properties of drill washes is favored to an unexpected degree when a combination of the above-mentioned cobalt compounds, i.e. of cobalt (ferrous) lignosulphonate and cobalt lignite, is used in water-based clay washes. The quantities used in the clay flushing are for cobalt-lignin sulphonate between 5 and 50 kg, preferably 15 to 25 kg, for cobalt-lignite between 2 and 50 kg" each time calculated per flushing fluid. The weight ratio between cobalt lignin sulphonate and cobalt lignite should preferably be chosen so that 1 part cobalt lignite contains 1 to 4 parts cobalt lignin sulphonate.

Ved tilberedning av spylevæsken» ifølge oppfinnelsen kommer det hensiktsmessig til anvendelse alkalihydroksyder i mengder som er tilstrekkelig til å opprettholde en pH-verdi over 7. When preparing the flushing liquid according to the invention, alkali hydroxides are suitably used in quantities sufficient to maintain a pH value above 7.

I den nedenfor oppførte tabell oppstilles en vanlig feltspyling uten og med tilsetning av oksydativt fremstilt krom-ligninaulfonat resp. kromlignit overfor en spylevæske ifølge oppfinnelsen med koboltligninsulfonat og koboltlignit. Måleresultatene viser at ved behandling med koboltforbindelsene under bibehold av de gunstige rheologiske egenskaper inntrer en drastisk nedsetning av vanntapet. In the table listed below, a normal field rinse is set out without and with the addition of oxidatively produced chromium lignin aulfonate or chrome lignite versus a flushing liquid according to the invention with cobalt lignin sulphonate and cobalt lignite. The measurement results show that when treated with the cobalt compounds while maintaining the favorable rheological properties, a drastic reduction in water loss occurs.

Fremstillingen av koboltligninsulfonat foregikk etter den under a) beskrevne metode således at det i sluttproduktet er tilstede ca. 1 vektprosent kobolt. Fremstillingen av koboltlignit foregikk etter den ovenfor under b) beskrevne behandlingsmåte, således at det i sluttproduktet er tilstede ca. 0,5 vektprosent kobolt. The production of cobalt lignin sulphonate took place according to the method described under a) so that the final product contains approx. 1 weight percent cobalt. The production of cobalt lignite took place according to the processing method described above under b), so that the final product contains approx. 0.5% by weight cobalt.
