Increasing the viscosity of the flushing liquid when introducing chemical reagents

The article deals with the research questions of viscosity reducers with the introduction of various chemical reagents. The results were obtained to increase the viscosity, various polymers were used, such chemical reagents include hypan, КМЦ, starch reagent, НЦ-1, K-4, K-9, НПВР and other reagents, and КССБ, ССБ was also used to contain the washing solution, a lubricant for reducing the viscosity of heavy clay solutions. From this result, it was found that when diluted with water using a flushing liquid, it usually worsens the remaining parameters and leads to an increase in the consumption of the weighting agent.
