MATHEMATICAL SIMULATION OF TEMPERATURE CONDITIONS OF HYDRATE FORMATION IN THE FIELD GAS COLLECTORS OF THE WESTERN PESTSOVAYA AREA OF THE URENGOI OIL AND GAS CONDENSATE FIELD

The article presents a mathematical model of temperature distribution for a gas fl ow in a pipeline with heat transfer through the wall. The model can be used in heat-exchanging apparatuses, in fi eld and main pipeline systems of natural gas transport and of gas-collecting header. In simulation, use is made of real production data directly from the Urengoi oil and gas condensate fi eld (OGCF). The simulation is carried out in a one-dimensional (hydraulic) approximation with account for the temperature distribution across the pipe (thermal boundary layer). The model includes two independent parameters that contain information on the heat-conducting properties of the gas and pipe walls with account for the thermal insulation of the pipeline. The resulting equation is recommended to be used for calculating heat losses by the gas-collecting header. The mathematical model developed by the authors can be used in the case where there is an insuffi cient amount of information, since it allows one to obtain some parameters directly by mathematical calculation and approximation. Note that the proposed mathematical model has shown suffi cient convergence with the well-known Shukhov formula for calculating the temperature distribution for a gas fl ow in a pipeline.
