Beschreibung
Zusammenfassung:	A method of servicing a wellbore penetrating a subterranean formation, comprising placing into the wellbore a cementitious composition comprising a crosslinked polymeric microgel, a clay, a cementitious material, and water. By incorporating the crosslinked polymeric microgel and the clay as disclosed herein, the cementitious composition can be used at relatively high temperatures. L'invention concerne un procédé d'entretien d'un puits de forage pénétrant dans une formation souterraine, comprenant le placement dans le puits de forage d'une composition cimentaire comprenant un microgel polymère réticulé, une argile, un matériau cimentaire et de l'eau. Du fait qu'elle comprend le microgel polymère réticulé et l'argile selon l'invention, la composition cimentaire peut être utilisée à des températures relativement élevées.
