METHODS OF CEMENTING IN SUBTERRANEAN ZONES PENETRATED BY WELL BORES USING BIODEGRADABLE DISPERSANTS
摘要
<p>The present invention provides methods of cementing subterranean zones penetrated by well bores using biodegradable dispersants. A cement composition of the invention comprises a hydraulic cement, sufficient water to form a slurry and a water soluble biodegradable cement dispersant comprising a polyamide graft copolymer containing at least one side chain formed from aldehydes and sulfur-containing acids or their salts.</p>
