Abstract
The paper presents the results of studies of natural gas hydrates in water-in-oil and water-in-asphaltene-resin-paraffin deposits (ARPD) emulsions conducted in the laboratory of technogenic gas hydrates of the Institute of Oil and Gas Problems, SB RAS. The kinetic aspects of the hydrate formation process in the selected emulsions, the prevailing mechanisms of hydrate crystals formation, the effect of the medium on the morphology of the formed hydrates are described in detail. The study of gas hydrates growth was carried out using the differential scanning calorimetry (DSC), as well as synthesis in a special high-pressure chamber.
