Modified Starch
Catalog NO.: AIMRSE-CHM-ADD-047 Manufacturer PN: CHM-STH-MOD
• Temperature resistance up to 120°C; especially suitable for non-dispersed systems under high mechanical drilling speed conditions; inhibits shale dispersion; unaffected by salinity; acid-soluble product.
Effectively controls mud filtrate loss while assisting in viscosity increase. Helps form a thin, elastic mud cake with low permeability, reducing the risk of sticking and sticking-out. Minimizes erosion of filtrate and mud solids.
This loss control agent is a high-quality pregelatinized starch product suitable for most water-based drilling fluid systems, including freshwater, seawater, and saturated salt cement slurries, with temperature resistance up to 120°C. The product itself does not increase viscosity but functions by coating drill cuttings, inhibiting the dispersion of active shale, and promoting expansion. To prevent fermentation caused by bacterial degradation, it is typically used in conjunction with a biocide to ensure sustained effectiveness.
