| Popis: | Downhole artificial lift is the most energy-intensive process at the oil companies. In the current economic conditions, the oil companies are forced to optimize the power consumption for production processes. To do this, you must have a methodology for calculating the energy consumption of all oil-producing equipment. Energy losses occur in all parts of the electrical submersible pump units: submersible motors, electrical cables, transformers and control station. There are analytical expressions that allow finding the power consumption in all elements of the pumping unit. However, the energy consumption depends on many process and operating parameters, such as density, viscosity, water content wellbore fluid, gas content, temperature in the borehole. The authors conducted a study on the impact on the power consumption of various technological and operational parameters. When adjusting the pump performance varies depression and reservoir, respectively, and the oil recovery wells. Therefore, to determine the optimal performance of the pump for the payment by a particular well is problematic. The relationship between the formation and the depression change inflow well fluid can be determined according to well testing. The results of this research can be useful to specialists in the development of the oil-producing enterprises of measures to optimize energy consumption. |
