Parametrización de un modelo numérico de bomba jet para el diseño de sistemas de levantamiento artificial con bombeo hidráulico

Abstract

This research presents the parameterization of a numerical model of jet pump for artificial lift systems with hydraulic pump. The parameters of this research was the information of well testing and simulations of computational fluid dynamics. The performance of the model is sensitive to the variation of the coefficients of frictional losses. According to the experimental information and analysis of this work, the coefficients that minimize the error were KN = 0.03, KS = 0.00, and KTD = 0.31 for the nozzle, suction, and throat-diffuser, respectively. The results of the model with these coefficients improve the predictive capacity of cavitation in order to reach an effectiveness of 90%. The parameterization provides a reliable model that calcule pump operating parameters with a great efficiency and accuracy, so it produce important optimization of production and reduce the costs of redesign and the implementation of an optimized geometry.
