Based on the processing of field data, it was found that the Joule-Thomson effect occurs in the well - formation system, which can be used to prevent certain types of complications. The essence of the application of the Joule-Thomson effect in well drilling to control some processes is to compensate the pressure drop by backpressure due to the temperature difference between the well - formation system. At the same time, accidents caused by pressure drops in wells drilled from semi-submersible drilling rigs are also prevented. Development of optimal hydrodynamic and thermodynamic calculation methods, creation of thermohydrodynamic methods, hydrodynamic complexes can become one of the main directions of development of oil industry. The process of pressure drop compensation by back pressure can be implemented in various ways. Nevertheless, the best method, according to the author, is the method based on regulation of wellhead temperature of drilling mud. Regulation of the temperature of the drilling fluid is one of the effective methods of controlling technological processes during well drilling. Thus, the article shows that at a known temperature of the fluid leaving the well, the temperature of the fluid entering the well provides a thermodynamically normal drilling process. Based on data on temperature changes at the wellhead, it is possible to control the pressure drop in the well - reservoir system.
