摘要：
The present invention provides methods of sealing conduits in multi-lateral wells whereby the sealant can withstand stress induced conduit movements without failure. The methods basically include the steps of preparing a hardenable epoxy composition having flexibility and resiliency upon hardening including an epoxide containing liquid or an epoxy resin and an epoxide containing liquid and a hardening agent. The epoxy composition is placed into a lateral well bore between a conduit therein and the walls of the lateral well bore and allowed to harden therein.
