| description | Fluider, som for eksempel kom pletteringsfluider, inneholdende minst ett alkalimetallwolframat og eventuelt minst ett chelateringsmiddel beskrives. Det beskrives også fremgangsmåter for å fjerne fra en borehulloverflate en filterkake som kan inneholde ett eller flere jordalkallmetallsulfater, ved hvilken filterkaken bringes i kontakt med kompletteringsfluidet ifølge oppfinnelsen. Det beskrives likeledes et borefluid som inneholder minst ett alkalimetallwolframat. Borefluidet inneholder fortrinnsvis dessuten minst ett emulgeringsmiddel eller overflateaktivt middel og minst ett fluid på hydrokarbonbasis. De forskjellige fluider ifølge oppfinnelsen kan også inneholde andre, konvensjonelle bestanddeler og eventuelt minst ett alkalimetallformiat. De nye fluider kan være hovedsakelig uten innhold av faste stoffer som følge av bruken av alkalimetallwolframatet.
Fluids, such as completion fluids, containing at least one alkali metal tungstate and optionally at least one chelating agent are described. Methods of removing a filter cake from a well bore surface, which may include one or more alkaline earth metal sulfates, is also described, wherein the method includes contacting the filter cake with the completion fluid of the present invention. A drilling fluid or mud is also described wherein the drilling fluid contains at least one alkali metal tungstate. The drilling fluid preferably further contains at least one emulsifier or surfactant and at least one hydrocarbon-based fluid. The various fluids of the present invention can contain other conventional ingredients and optionally at least one alkali metal formate. The present invention permits the fluids to be essentially solids free due to the use of the alkali metal tungstate. |
