摘要：A method of preventing intrusion of fluid into a horizontal well bore. A quantityof liquid composition capable of gelling and containing a breaker is introduced into ahorizontal well bore up to a point corresponding to the bottom of the intrusion zone.After the liquid composition gels into a temporary gel, a second liquid compositioncapable of gelling into a permanent gel is introduced into the zone to shut off fluid flowfrom the zone. The temporary gel prevents flow of the permanent gel into thehorizontal well bore. Thereafter the breaker in the temporary gel causes the gel torevert to a liquid, which is removed from the horizontal well bore upon production of thewell.
