abstract

  • Multiphase pumping has consolidated itself as the state of the art technology in crude oil transport for declining and marginal fields. Several types of pumps have been applied or developed for such service, opening a new research trend worldwide. In this research we studied the progressive cavity pump performance with two-phase flow. Our aim was to obtain the pressure and temperature profiles along the pump's stator, and to observe its behavior under different sets of variables such as gas void fraction, rotational speed and Δp. The knowledge that can be acquired will be useful to estimate how flow conditions can be affecting the pump's life and the smoothness of the pump performance. The results showed that for single-phase flow at low Δp the maximum pressure is not located at the pump outlet as it would be expected. The pressure distribution in the pump with two phase flow is completely different to the latter case, being found that within the pressure range of the experiment the cavities are kept sealed almost along the whole pump. For any point of operation the maximum temperature is found in the intermediate stages.
