Estudio para la optimización de la limpieza de hoyo en pozos horizontales y altamente desviados del campo Edén Yuturi

Abstract

This work is a study of the optimization of the cleaning up wellbores, by analyzing the operational problems associated with the cleaning presented during the years 2015 - 2017 in the Yuturi Eden field. These problems are obstructions in the pipeline, problems of settling of tools, sticking of tools and presence of waste in the EPS equipment. In order to solve these problems, the performance of the different specialized tools for cleaning and the performance of viscous pills has been analyze. The viscous pills were made in the laboratory with clarified xanthan gum, the concentrations chosen were 2 lb / bl, 2.5 lb / bl, 3 lb / bl, 3.5 lb / bl, 4 lb / bl, 4.5 lb / bl. The laboratory tests were made in them, in order to determine their rheological properties. The information obtained served to make the simulations in the VCS program and determine the minimum concentration necessary to improve the cleaning results. To evaluate the tools, a comparative analysis was made between them taking into account the type of work, the degree of difficulty of the cleaning, the mechanical configuration, the type of arrangement and the amount of waste collected by each one.
