Product features

This product is a kind of polyacrylamide copolymer. In overhaul operations, in order to avoid harmful pollution such as water sensitivity, salt sensitivity, alkali sensitivity, wetting inversion, surface adsorption, water lock, blockage, permeability drop, etc., it is necessary to provide protective fluid with no damage and no residue, able to withstand huge differences in formation pressure and temperature, and temporary plugging effect according to the characteristics of the formation and operation. The degradation fluid also has good dispersion and suspension performance, which ensures the rheological property and sand carrying property of workover fluid.

Method of application

The dosage varies depending on site conditions to obtain the desired viscosity of the drilling mud. The dosage is typically 0.1 to 0.4 percent in clear water and 0.4 to 1 percent in saturated brine. It is recommended to prepare 1-2% polymer aqueous solution and then add it to drilling fluid as required.

Store the product in dry and cool place, avoid insolation. Shelf life is two years.
