Description
Product Description
DF-03 is modified starch by inserting hydration groups and high temperature stabilizer to improve the water solubility and temperature resistance (up to 135 ℃). And ensure its good fluid loss performance under both low and high temperature. DF-03 is an environmental friendly, low viscosity, salt resistance (up to saturation) filtration reducer. Its recommend dosage is 1.0%-2.0%.

Features
Reduce filtration loss effectively.
Increase viscosity slightly.
It is degradable, non-toxic and does not harm the environment.
The operating temperature can reach 135℃.
Resist salt to saturation, reasonable calcium and magnesium resistance. so it can be applied in various drilling and completion fluids.
Good filtration control performance under the condition of both low and high temperature, and has wide applicable temperature range.
It does not contain polymer products,which has little effect on rheology of drilling fluid and does not cause viscidity of drilling fluid
