摘要

PROCESS FOR UTILIZING A SILICATE/SILICA CEMENT IN OIL FIELD APPLICATIONS A process for formulating and applying a silicate/silica cement composition to the treatment of a wellbore comprising the steps of mixing an appropriate silica compound with an aqueous water-soluble silicate solution and injecting the mixture into the wellbore in such a manner as to penetrate void spaces in or adjoining the wellbore. The mixture is cured in place, hardening into a solid impermeable cement which plugs the penetrated void spaces.
