SPNH Lignite Resin for Drilling Fluid

SPNH lignite resin is black powder, which is made of phenol, formaldehyde, nitro humic acid and so on by grafting copolymerization under certain conditions. It contains a variety of active groups, and its temperature resistance can reach 200 ℃. It can significantly reduce the water loss of fresh water and saturated brine drilling fluid, and significantly improve the quality of mud cake and rheological properties of drilling fluid.

Product Features

1. Strong temperature resistance, good water loss reduction performance and extensive anti pollution ability.

2. The viscosity effect is low and the drilling fluid has good rheology.

3. It can be used with various drilling fluid systems with good compatibility. The recommended dosage is 1-3%.
