Abstract
Ved brønnvasking sirkuleres en vaskevæskeblanding i brønnen og vasker løs samt tar med seg smussbelegg, skitt og foruren- sende stoffpartikler som måtte klebe til brønnveggflåten. Brukt, tilsmusset vaskevæskeblanding betraktes som spesialav- fall og krever etterbehandling/destruksjon. Ifølge oppfinnel- sen foreslås det å benytte en ustabil vaskevæskeblanding, nemlig en baseoljebasert spalteemulsjon inneholdende såpe og vannbasert aktivatorvæske som opprettholder sin sammen- blandingstilstand under brønnvaskingen, for å sikre et godt vaskeresultat, men som i brukt, tilsmusset tilstand - som følge av sine iboende spaltningstilbøyeligheter - etter en viss hviletid i tank eller annen egnet beholder, for eksempel i et par døgn, tillater at ikke-permanent blandbare faser, olje og vann, skiller seg, med den letteste oljefase flytende på toppen i gjenanvendelig, ikke-tilsmusset tilstand, og hvor den underliggende vannfase etter denne hviletid vil inneholde alt smuss, såpe, aktivator etc. og alene - i en mengde under- skridende ca. 40 volumprosent av den totale vaskevæskeblan- ding - som derved utgjør spesialavfallet.In the case of well washing, a wash liquid mixture is circulated in the well and washes loose as well as taking away dirt, dirt and pollutant particles that may have to adhere to the well wall raft. Used, dirty wash liquid mixture is considered special waste and requires finishing / destruction. According to the invention, it is proposed to use an unstable wash liquid mixture, namely a base oil-based slurry emulsion containing soap and water-based activator liquid which maintains its mixing state during the well wash, to ensure a good washing result, but as used, as a result of its soiled state - as a result. decomposition tendencies - after a certain rest period in the tank or other suitable container, for example for a couple of days, allow non-permanently miscible phases, oil and water to separate, with the lightest oil phase floating on top in a reusable, non-soiled state, and where the underlying water phase after this rest period will contain all the dirt, soap, activator etc. and alone - in a quantity of below approx. 40% by volume of the total washing liquid mixture - which thus constitutes the special waste.
