High Tempersture and Salt Resistance Lignite-Pheno

Lignite-Phenolic Resin SPNH 1. Property It is the temperature and salt resistance of the drilling fluid filtrate and composed of the sulfonated phenol-formaldehyde resins and sulfonated lignite. Can use together with Sulfonated lignite, Sulfonated tannin, etc. It is one of the ideal high temperature deep well mud systems. 2.

Use SPNH to draw into the sulfonic group in benzene ring unit. And the benzene ring linked with carbon atoms, high temperature resistant.Owing to thephenol draw into the sodium sulfonate –SO,NA in ortho para orientation, well hydration and hydrone .So, has resolved its water-soluble. Determines its salt-resistant, anti-calcium, high temperature and pressure drop to reduce the role of water loss. Sulfonated phenol-formaldehyde resin as deep mud treatment agent, With high performance of high-temperature and high-pressure fluid loss, salt resistant,anti-CA, reduce the friction coefficient of mud cake,etc. have an important role in the consolidation of wall, anti-collapse and anti-cards.Propoese to dosage 1-3% 4. Storage & Package 25Kg net sealed in 4-in-1 compound paper bag with plastic lining during storage and transport see that the bag is intact. But its property is not affected even if it becomes damp.
