At present time the techniques of investigation and interpretation of thermal research data is formulated mainly on the base of data analysis for one-phase flows of oil, water and gas. But in the real conditions it is observed the multiphase flows in the formation and well. Processes of putting the well in operation and well shut-in, swabbing, and compressor oil well completion and formations are characterized by the unsteady pressure field. And the pressure in the well can increase above the reservoir pressure, and after that decreases below the reservoir pressure and pressure of saturation of oil by gas. Thus, in the formation it is realized the regimes of multiphase flows related to the transfer of water pump from the wellbore to oil saturated formation to the fluid production from the formation with oil degassing. Temperature distribution of the formation in this case is caused by the Joule-Thomson, adiabatic effects and heat of fluid degassing. Oil and water throttling leads to temperature increasing, and oil degassing to temperature decreasing, An informative thermal technique of research of well and formation is based on the regularities of temperature anomaly changes. In this work the main regularities of temperature distribution formation at arbitrary change of bottomhole pressure under the conditions of multiphase flow taking into consideration the thermodynamic effects and oil degassing are numerically researched. The possibility of field problem solution according to thermohydrodynamic well research is shown.
