Product Description
Lignite Resin for Drilling Fluid SPNH
Handling methods and dangerous data shall be referred to MSDS.
1. The SPNH is a filtration reducer utilized in drilling fluids, synthesized through the copolymerization of brown coal and formaldehyde. It effectively enhances mud cake quality, reduces drilling fluid filtration, and decreases viscosity. Withstanding temperatures up to 200 ºC, SPNH exhibits excellent resistance to salt and can be applied in both freshwater and saline drilling fluids. The recommended dosage ranges from 7.0-14.0ppb.
| Items | Specifications | |
| Appearance | Black-brown powder | |
| Moisture, % | ≤18.0 | |
| Water Insoluble, % | ≤12.0 | |
| pH | 9.0-10.2 | |
| FLAPI, ml | Fresh water slurry | ≤10.0 |
| Sodium chloride slurry | ≤15.0 | |
| FLHTHP, mL | Fresh water slurry | ≤30.0 |

SPNH can resist salt, reduce filtration, and can be applied to various freshwater and saline drilling fluids.
SPNH has a certain viscosity reducing effect, which helps to adjust the rheological properties of drilling fluid.
SPNH can resist high temperature up to 200 ºC, so that it can be applied in deep wells.
Compatible with other additives.
