Provided is a fluid dispersion for drilling, characterised in that polyoxalate, which is a hydrolyzable resin material, is dispersed in an aqueous medium. The fluid dispersion for drilling, according to the present invention, has a hydrolyzable resin material that is highly hydrolyzable even at low temperatures of 80°C or 60°C or less dispersed in an aqueous medium, and thus the fluid dispersion for drilling can be used when gathering by means of boring drilling methods such as riserless drilling, rotary drilling and hydraulic fracturing. |
