High Polymer Emulsion Encapsulator & Inhibitor for
Drilling Fluid HP**0
Product Data Sheet
Product Description
High Polymer Emulsion Encapsulator & Inhibitor for
Drilling Fluid HP**0 is a water soluble emulsion by
copolymerization. Main materials are acrylamide, acrylates and its
derivatives, auxiliary materials are mineral oil and surfactant.
Its viscosity-average molecular weight is up to 6 million and it is
mainly used to inhibit clay from hydration swelling.
Advantages
Provides shale inhibition and limits cutting dispersion, is
beneficial to prevent bit balling
Reduces fluid loss
Low viscosity effects, maintain polymer drilling fluid’s
rheology
Resistance to contamination of salt and
calcium-magnesium, can be used in brine and saturate brine drilling
fluid systems
Readily dispersible, quickly soluble and does not form “fish
eyes”
Stabilizes borehole, reduces torque, improves quality of mud
cake
Passes solid equipment smoothly, high efficiency,
economical
Easy to use, convenient to add, no powder contamination
Application Range and Method
HP**0 not only has an effect on inhibiting shale from
hydration, dispersion and encapsulating cuttings, but also
inhibiting water sensitive formation from water swelling. It’s
suitable for mud-making and water sensitive formations. Recommend
to use in polymer drilling fluid systems.
HP**0 can be formulated into aqueous solution for use or mixed
in drilling fluid directly. Suggest mixing uniformly and slowly or
mix intermittently. Be careful not to add too fast, otherwise it
will form a plug flow.
It should be added timely to maintain the inhibition capacity
of drilling fluids. Recommend dosage is 0.4% to 0.8%.
