The study is focused on the results of kinetic analysis of processes of crystallization and melting of hydrates synthesized in model systems ``natural gas + water'' and ``natural gas + asphaltene-resin-paraffin deposits (ARPD) + water''. Synthesis and decomposition of hydrates in the systems under investigation were carried out in a calorimetric cell of differential scanning calorimetry (DSC). The kinetics description of processes is carried out applying the Avrami equation. Based on the obtained data, the rate constants, order of reactions, and half-life time periods of formation in gas and oil wells has shown that $P$, $T$-conditions hydrate-paraffin formation correspond to the actual thermobaric conditions of several oil and gas fields located in the permafrost area.
