摘要： High-specific-gravity micronized particulates, added to cement slurries in conjunction with certain high-molecular-weight water-soluble polymers, improve fluid-loss control of cement slurries during placement in subterranean wells. Preferably, the particulates have a specific gravity higher than 3, and a median particle size smaller than 3 µm. Preferred particulates include barite, manganese tetraoxide, titanium oxide, iron titanium oxide and aluminum oxide.

摘要： The present invention provides a versatile additive for improving the properties of a cement slurry made with portland cement and to be utilized in well cementing, said versatile additive comprising type of silicates and/or borates that inhibit gelation occurring with the interstitial phase. The additive of the present invention improves significantly the rheology (i.e., strong dispersing effect) and can even overcome severe gelation problems. At temperature above about 88°C (190°F) the additive acts as retarder aid, enabling to reduce considerably the concentration of retarder required to achieve a given thickening time.
