Means to suppress microbiological degradation of drilling fluid based on polysaccharides, process for its preparation and a method of suppressing microbiological degradation of drilling fluid based on polysaccharides

摘要

1. The agent for suppression of microbiological degradation of drilling fluids on polysaccharides comprising tris monohydrate (hexahydro-1H-azepin-2-one) dichloride medi.2. A method for inhibiting microbial degradation of drilling fluids on polysaccharides by adding a biocidally active substance, characterized in that the effective amount of the monohydrate was added tris (hexahydro-1H-azepin-2-one) dichloride medi.3. Application monohydrate tris (hexahydro-1H-azepin-2-one) copper dichloride as a means to inhibit microbial degradation muds based polisaharidov.4. A method for producing tris monohydrate (hexahydro-1H-2-one) copper dichloride, characterized in that a solution of hexahydro-1H-azepine in alcohol and / or water added copper chloride dihydrate in a ratio of 3: 1 was stirred for 1-3 hours at a temperature of 20-80 ° C, then cooled to 5 ° C, the precipitate was filtered off and the filter prmyvayut alcohol, dried in a vacuum desiccator over calcium chloride.
