The article presents the results of research on the development of effective compositions of thermo-salt-resistant composite chemical reagents using local and secondary materials. Due to the high salinity of the reservoir water for the preparation of drilling fluids, water is brought from long distances and costs increase significantly. Based on the conducted research, we propose to introduce 3–20% (depending on the amount) of the KHR-R reagent to the composition of the drilling mud as an acid-soluble additive when opening fractured oil and gas reservoirs.
