Sodium Polyacrylate Used as Filter Loss Depressant Agent 

Product Information Sodium Polyacrylate water loss reduction agent for drilling mud. Adding sodium polyacrylate to drilling mud can improve the lubricity and stability of the slurry, reduce the water loss of drilling mud, effectively prevent jamming and unjamming, and improve drilling efficiency. Principles of action Filter loss reducers are chemical agents that reduce the filtration loss of drilling fluids. Filter loss reducers are mostly water-soluble polymer compounds, which can reduce the filtration loss of drilling fluid through the following ways. Clay particles in drilling fluid require appropriate size distribution, and more fine clay particles are required. The drilling fluid with high filtration loss has more coarse particles on the one hand, and on the other hand, the fine particles have been flocculated into coarse particles, and there are fewer sol-gel fine particles (<100pLm) in the system. This kind of drilling fluid with more coarse particles and less fine…
