Annotation:

The article considers the problems of opening and developing complexly-composed carbonate reservoirs using polymer drilling fluids of various degrees of mineralization. At the same time, a significant number of intensive oil shows with the discovery of deposits is associated with unconventional reservoirs in the "domanikites" of the Upper Devonian and are represented by zones of increased fracturing. The article presents the results of field and experimental studies. Recommendations are given for choosing the composition of drilling fluids for opening carbonate reservoirs and testing the formation.
