Abstract

Una composición para disolver depósitos de torta de filtro dejados por el fango de perforación en agujeros de pozos, incluye una solución de ácido orgánico soluble en agua y una sal seleccionada apartir de cloruro de metal alcalino, formato de metal alcalino, tetrafosfato ácido, cloruro alcalinotérreo o tiofosfato de metal alcalino. Cada uno de los ácidos y sales están presentes en la escala del 0.5 al 75 por ciento en peso/peso de la composición. El ácido preferido es ácido cítrico, y la sal preferida es cloruro de potasio. La composición es útil como un adjetivo para liberar el tubo pegado en los agujeros de pozos, y como un espaciador del fijador para el tubo de cimentación en los agujeros de pozos. Un uso tradicional de la composición es como un fluido de estímulo de pozos en pozos de producción de petróleo y gas, en donde la composición es efectiva para disolver la torta del filtro que bloquea los poros en la información de producción filtro que bloquea los poros en la formación de la producción.A composition for dissolving filter cake deposits left by drilling mud in well holes, includes a solution of water soluble organic acid and a salt selected from alkali metal chloride, alkali metal format, acid tetraphosphate, alkaline earth chloride. or alkali metal thiophosphate. Each of the acids and salts are present on the scale of 0.5 to 75 weight / weight percent of the composition. The preferred acid is citric acid, and the preferred salt is potassium chloride. The composition is useful as an adjective for releasing the glued tube in the well holes, and as a fixer spacer for the foundation tube in the well holes. A traditional use of the composition is as a stimulus fluid from wells in oil and gas production wells, where the composition is effective in dissolving the filter cake that blocks the pores in the filter production information that blocks the pores in production formation.
