This fluid loss additive features excellent salt and high-temperature resistance, effectively controlling water loss of cement slurry in complex downhole environments. It adapts to temperatures over 100℃ and high salinity conditions, forming a dense filter cake to reduce moisture loss and ensure the strength development of cement stone. With good dispersibility and strong compatibility with other admixtures, it significantly improves the rheology of cement slurry, suitable for various cementing operations.
The fluid loss additive is typically used by dry blending or liquid addition during cement slurry preparation. For dry blending, it is mixed with cement powder in proportion (usually 0.5-3% by weight of cement) before adding water. In liquid form, it is dissolved in mixing water and then incorporated into the slurry system. The dosage should be adjusted based on downhole temperature, salinity, and cement type to ensure optimal water loss control. It is crucial to maintain uniform dispersion through mechanical agitation to prevent agglomeration. The additive should be compatible with other admixtures like retarders or dispersants, which can be added sequentially under continuous stirring. Proper pre-testing in laboratory conditions is recommended to determine the ideal formulation and usage procedure for specific well conditions.
