High Polymer Emulsion Encapsulator & Inhibitor for Drilling Fluid SHALE- PLUS EMULSION 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. Provides shale inhibition and limits cutting dispersion, is beneficial to prevent bit balling. pH-sensitive with an optimum pH range of 8.5 to 10.5. At pH levels above this range, hydrolysis may convert.
Its advantages are
-Reduces fluid loss,
– High viscosity effects, maintains 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 , reduces torque, improves quality of mud cake
– Passes solid equipment smoothly, high efficiency, economical
-Easy to use, convenient to add, no powder contamination
