Cementing compositions and use of such compositions for cementing oil wells or the like |
摘要 |
The slurries were prepared using a reference slurry having a density of 16.4 lb/gal(US) (1.965 g/cm3) of cement, with porosity of 55.18%. The cement was a class G Dickerhoff North cement. The slurries were prepared in the presence of on agent at a concentration of 0.4% by weight of cemenit (BWOC) and of an anti-foaming agent at a concentration of 0.03 gallons per (94 pound) sack of cement (gps); (a concentration of 0.1 gps corresponds to 0.90 liters of anti-foaming agent per 100 kg of cement). The suspension agent was added to the mixing water, and mixing took place at 4000 revolutions.
