Abstract

Fremgangsmåte for å redusere tap av brønnvedlikeholdsfluid til en underjordisk formasjon. En polymerløsning og en aktivator blir brakt i kontakt i formasjonen og danner derved en utfelling som i det minste delvis blokkerer fluid fra å strømme videre inn i formasjonen. Fluidet kan være en borevæske, en sementblanding, en overhalingsvæske eller kombinasjoner av de nevnte. Polymerløsningen kan omfatte en vandig polyvinylpyrrolidon løsning og aktivatoren kan omfatte en formiat lake. I en utførelsesform blir polymerløsningen og aktivatoren brakt i kontakt før fullføring (komplettering) av en boreoperasjon i brønnen. I andre utførelsesformer blir de brakt i kontakt før fullføring av en primær eller sekundær sementeringsoperasjon i brønnen. Når det er ønskelig kan utfellingen enkelt og raskt fjernes fra formasjonen ved å løse den opp i ferskvann.Procedure for Reducing Loss of Well Maintenance Fluid to an Underground Formation. A polymer solution and an activator are contacted in the formation, thereby forming a precipitate which at least partially blocks fluid from flowing further into the formation. The fluid may be a drilling fluid, a cement mixture, a supernatant or combinations of the above. The polymer solution may comprise an aqueous polyvinylpyrrolidone solution and the activator may comprise a formate lake. In one embodiment, the polymer solution and activator are contacted prior to completion (completion) of a wellbore operation. In other embodiments, they are brought into contact before completing a primary or secondary cementing operation in the well. When desired, the precipitate can be easily and quickly removed from the formation by dissolving it in fresh water.
