摘要：
The present invention provides sealing methods and compositions for use in subterranean zones penetrated by well bores. The methods of the invention basically include the steps of preparing a sealing composition which includes an aqueous silicate solution, an epoxide containing liquid and a delayed epoxide hardening agent, placing the sealing composition into a subterranean zone and allowing the sealing composition to set into a rigid impermeable sealing mass in the zone.
