CEMENT COMPOSITIONS WITH IMPROVED FLUID LOSS CHARACTERISTICS AND METHODS OF CEMENTING IN SUBTERRANEAN FORMATIONS
摘要
<p>The present invention provides cement compositions comprising an improved fluid loss control additive, and methods for cementing in a subterranean formation using such cement compositions. The cement compositions comprise a hydraulic cement, water, and a fluid loss control additive comprising at least two polymers connected by a pH-sensitive crosslink. Optionally, other ingredients may be included in the compositions.</p>
