SL-II is a water-soluble polymer copolymerized from a variety of propylene and vinyl monomers. In drilling fluids, it has multiple functions such as high-efficiency thickening, strong filtration reduction, cuttings coating, and inhibition of shale hydration. It is particularly suitable for drilling operations in high-temperature deep wells and complex salt and gypsum formations.
