Subject to grade specifications, Liyuan CMC/PAC functions within drilling fluids primarily to mitigate fluid loss and/or enhance viscosity of the mud system.
Drilling fluids formulated with Liyuan CMC/PAC exhibit exceptional overall stability and are resistant to high temperatures, saline environments, and fungal degradation. Neither elevated pH maintenance nor supplementary biocidal additives are required for system preservation.
Even under saline formation conditions at operating temperatures exceeding 120°C, drilling fluids formulated with Liyuan CMC/PAC can form thin, dense filter cakes with low permeability on the borehole wall, while maintaining consistently low filtrate loss performance.
