Abstract
A cellulose fiber nano-dispersion pressing-in device for pressing a liquid, in which a cellulose fiber of a conifer-derived pulp is nano-dispersed, into a stratum, includes a grinding means for grinding the conifer-derived pulp in water, a dilution means for diluting a cellulose fiber-containing liquid obtained in the grinding means and a pressing-in means for pressing a nano-dispersion of the cellulose fiber obtained in the dilution means into a well. Therefore, it is applicable to water-stopping operation in a civil engineering process or to a process of industrial production of hydrocarbons such as crude oil, gas and the like for improving the recovery rate thereof.
