Kratasol BM - buffer powder is intended for obtaining a washing buffer liquid serving for separation of various grouting and drilling fluids in composition and efficient washing out of the latter residues from the walls of wells with a dynamic temperature from 0 to 100 ° C.

Application area

The main area of ​​application is the separation of drilling and grouting mortars during the cementing process, preventing mixing, as well as increasing the degree of substitution of the drilling mud with cement and cleaning the walls of the well.


  • Good washing ability;
  • The buffer composition is compatible with drilling and backfilling solutions;
  • Prevents the formation of thick, difficult-to-pumped mixtures;
  • Increases the completeness of the replacement of the washing liquid with a grouting mortar;
  • Improves the quality of adhesion of oil well cement.


The recommended dosage of the additive is 3 - 50 kg / m 3 of solution in terms of dry matter. The range of recommended dosage supplements can be extended. The optimum dosage of the additive is established during laboratory selection. It is recommended to dispense with an error of not more than ± 2%.
