Thermally-activated, high-temperature cement suspending agent

摘要

The present invention relates to methods of providing a cementing fluid comprising an aqueous liquid, a hydraulic cement, and a cement suspending agent that comprises a crosslinked particulate formed by a reaction comprising a first monofunctional monomer, a primary crosslinker, and a secondary crosslinker; placing the cementing fluid in a wellbore penetrating a subterranean formation; and allowing the cementing fluid to set therein.
