RS-230 is used as a hydrocarbon base in the technology of preparing heat-resistant invert emulsion drilling fluids. RS-230 allows the preparation of invert drilling fluids with a flat rheological flow profile, which ensures high technical and technological parameters of drilling in difficult geological conditions, especially in conditions of narrow ranges of regulation of the equivalent circulating density, and prevents loss of stability when drilling in shale rocks, and also prevents loss of drilling fluid due to hydraulic fracturing of poorly cemented formations. Optimally selected synergistic properties of the PS-510 emulsifier and the PS-230 hydrocarbon base are achieved by the most effective parameters of the emulsion, such as high stability, minimum viscosity at a high water-carbon ratio and flat rheological profile.
The high flash point ensures full compliance of the prepared invert drilling fluid with industrial and fire safety requirements in oil and gas industry.
RS-230 is highly effective for preparation of "oil in water" emulsions of different purposes. RS-230 is effective for preparation of oil-based well-killing fluids and breakdown fluids .
