[Abstract]:With the middle period of oil development, the reservoir pressure is high, the formation pressure is maintained, and the water injection is large, because the electric submersible pump is often required to deviate from the design efficiently, and the frequency modulation technique can meet the requirements very well. The frequency modulation is better applied to the submersible electric pump system and the CFD technique is applied to the numerical experimental study of the flow field in the submersible electric pump. The energy saving analysis of the parallel frequency modulation selects a certain type of submersible electric pump as the research image, and the guiding flow part is used as the dimensional fluid domain, and the structure grid is drawn. The calculation method of fluid dynamics model and the numerical calculation of flow field and flow field in electric submersible pump by using CFD technique are determined. By means of calculating data processing, the external characteristic curves such as pressure field and degree field of harmonic conductance are obtained. The flow rate and the hydraulic performance of the submersible electric pump are studied. The results show that the non-design flow rate and the loss in the diversion channel are large, and the efficiency of the designed pump is the highest in the high efficiency of each rotation. The internal flow field structure of the submersible pump is more than that of the submersible pump, but the pressure field and the degree field will be changed with the oil nozzle to adjust the internal flow field. The simulation results show that the internal flow field of the submersible pump should be adjusted by the nozzle with good hydraulic performance. That is, the hydraulic loss is small when the oil nozzle adjusts the fluid flow in the pump channel, and the loss is large, so the oil nozzle adjusts the phase and frequency to produce the energy saving effect. This paper studies the modification design of submersible electric pump and the wide operation of frequency modulation, which provides the theoretical basis and technical guidance.
