Drilling Mud Chemical Solid Additive Partially Hydrolyzed Anionic Polyacrylamide

Mineral Field

The flotation method is normally used in mineral processing. The mineral attaches to the bubbles and comes up to the pulp surface. Polyacrylamide could be added to the ore pulp to increase the adhesion and absorption between minerals and bubbles. This could help increase the recovery rate of minerals. Most minerals need dewatering during mineral processing. Polyacrylamide could also help improve the dewaterability of powder peat, which is used as a heavy metal catcher and has poor dewaterability. In addition, due to the activity of polyacrylamide, it could shorten the stirring and heating time to reduce energy consumption.

Oil and gas Field

For the well drilling, drilling fluid is applied to reduce the abrasion of equipment, reduce jamming of drilling tools, and prevent leakage and collapse. Polyacrylamide is added to the drilling fluid to adjust the rheological property of the drilling fluid, so as to carry lithic fragments, lubricate drill, and facilitate drilling. Polymer flooding technology needs high molecular weight polyacrylamide to increase the viscosity of infusing water. The oil-gas mobility ratio is improved. Then the water will replace the oil and drive it out, which improves the oil yield. In the fracturing process, polyacrylamide is added to the fracturing fluid due to its high viscosity, low frictional resistance, good sand-carrying ability, easy to prepare and low cost.
