Annotation:

The results of the analysis of complete watery extraction of soluble salts in a ratio of 1:5 (amount of drilling slurries (DS) to distilled water), easily soluble salts (ESS) out of 30 DS samples of the oil fields of PJSC “LUKOIL - Western Siberia” (KHMAO-Yugra) are presented. It is shown that the ESS content of the majority of samples is not dangerous to the components of the KHMAO-Yugra environment. The accounting for the results obtained allows increasing the validity of environmental protection measures when drilling oil and gas wells.
