Abstract—The raw materials base of brown coals for the production of heat-resistant polymer–lignite chemical reagents was selected based on a comparison of the technological parameters of water-based drilling fluids treated with various nanomodified powdered complex polymer–lignite chemicals. On the basis of lignin–alkaline reagents, a highly heat-resistant fluid-loss reducer, a complex low-thixotropic thinning agent, a complex inhibitor of shales, clays, and clay minerals, and a stabilizer of unstable clay and argillite deposits were developed.
Keywords: brown coals, lignin–alkaline reagent conversion, technological complex, nanomodified complex additives, drilling chemical reagents
