On the basis of the methods and equations of mechanics 
of multiphase systems a system of ordinary differential equations 
describing the hydrodynamics and thermal physics of a flow in the 
gas main in the presence of deposits of gas hydrates on the duct walls 
has been obtained. Some methods for preventing and controlling the 
formation of hydrates in the process of natural gas transport in a 
pipeline have been considered.
