Modeling of oil reservoirs heat losses by nanodimensional cellular automata
Статья научная
The oil and gas industry plays a crucial role in the Russian economy. One of the ways to increase its energy efficiency is to reduce unproductive losses. Losses of oil and petroleum products occur at all stages of the oil and gas complex from hydrocarbon extraction to processing and transfer to secondary product consumers. Unavoidable losses in the system are caused by losses of oil and oil products from evaporation during excessive heating by solar radiation during storage in tank farms. In the cold season, intensive external cooling with outside air leads to increased product viscosity and increased cost of electricity for its transfer. To avoid such situations, strict maintenance of the temperature regime of the reservoir by minimizing external heat gains and its own heat losses is re-quired. The article describes the simulation of heat transfer through the heat-insulated wall of the oil reservoir of one of the linear main station of oil pumping. The construction of the temperature graph through the outer fence is performed by the method of nanoscale cells of cellular automaton. The simulation was carried out for three dimensions of the field of cells. It is shown that for the task, the optimal structure is a field of 560 simulation cells.
