The article deals with the problems associated with the ""invasion"" of produced water into the composition of drilling muds in the process of drilling wells in anomalous conditions. It is marked that various types of complications, particularly, debris and collapses, emersion and adsorption cause very serious problems in the well construction, for the elimination of which large investments are required. For example, drilling mud influenced by produced water was used in some fields of the Republic. The electrical conductivity parameter was estimated based on the carried out research. This indicator allows evaluating the physical-chemical properties of the drilling mud before and after the treatment with formation fluid. It should be noted that the good electrical conductivity of the drilling mud is also significant for geophysical surveys. In order to preserve required properties of the drilling mud under conditions of ingress into the composition of the produced waters, the treatment of the drilling mud with salt-resistant polymeric reagents is recommended.
