shale inhibitor

详情

Its viscosity-average molecular weight is up to *0 million and it is mainly used to inhibit clay from hydration swelling. 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 *0 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%.
