· Under the condition of 120 C, using 6% SSS/HAM/IA ensures that the API fluid loss of saturated brine cement slurry systems is less than 50 mL, and strong salt resistance is retained. This is due to the cross-linking properties of the HAM molecule, which causes the terpolymer to exhibit a cross-linked structure, improving SSS/HAM/IA fluid

Abstract. A new organic fluid-loss additive for neat and gel cement slurries has been developed for use in squeeze operations to provide controlled dehydration of the slurry and, thus, fewer job failures. In addition, this additive provides greater fill-up behind pipe, even in highly porous formations. This material is compatible with bentonite materials and all
