Abstract
The effect of the demulsifier composition on the destruction of local oil-water emulsions was studied in this work. One of the urgent problems in the development of deposits is to increase the efficiency of the preparation of hydrocarbons in the fields. The solution of this problem makes it possible to significantly increase the degree of oil preparation, reduce the loss of hydrocarbons with drainage waters, thereby improve the environment and bring additional profit to the enterprise. A complex of theoretical and experimental studies was used, consisting in generalization and analysis of literary data, as well as by analogy, modeling, quantitative and qualitative observation, laboratory tests, conducting a multifactorial experiment, data processing using methods of mathematical statistics. Information processing tools based on computer software products were used. The results of laboratory tests of oil-water emulsion, physico-chemical analysis of water composition, new chemical reagents-demulsifiers recommended for field testing are presented. It can be concluded, based on the research conducted, that the demulsifier EASY-DE03-15 is the most effective reagent for dehydration of oil-water emulsions and desalination of MIX samples.
