Drilling Fluid and Completion Fluid | Year: 2012
A kind of filtration control additive is synthesized mainly from polypropylene, carboxyl calcium group, monomer of sodium 2-acrylamide-2-methylpropanesulfonate and macromolecule groups with surface activity. The experimental results show that using this filtration control additive, with the content of 0.5%, the filtrate volume of saturated salt water is only 5.6 mL, and different drilling fluid systems have good comprehensive performances after rolling 16 h at 120 °C, which is value to spread out.
