To date, various thermochemical compositions have been developed and used for treating the bottomhole formation zone (BFZ). The most effective in solving the problems of cleaning the bottomhole zone from organic deposits are thermochemical compositions. thermochemical fluids (TCF) are aqueous solutions of two inorganic salts, during the reaction a large amount of gas and heat are released. The components of thermochemical fluids are most often mixtures of nitrogen-containing
compounds capable of entering into a redox reaction with each other.
The idea of the method of thermochemical treatment (TCT) using TCF is to creat a kind of thermochemical gas generator, during operation, a chemical reaction occurs with the release of a large amount of gas and heat. Both of these factors together create favorable conditions for cleaning the bottomhole zone from asphaltene-resin-paraffin deposits (ARPD), increasing well productivity and oil recovery.
