| Abstract: | A formulation of the superfine slurry for plugging the oil reservoirs with high water cut was selected by measuring the needle penetration, thickening time, compression strength and permeability of the superfine slurries in laboratory. The experimental results show that, although the slurries with the low ratio of w(水) to w(灰) have high compression strength after solidifying, they have great consistency and short initial setting time; therefore, they do not suit the use in field. When w(水)/ w(灰) is 0.75 and the mass fraction of retardant is 1.5%~1.8%,the initial setting time, compression strength and permeability are suitable. The application result of the selected slurry in Henan Oil Field is satisfied. |
