Diseño de adaptación de una centrífuga de fluidos para su uso en análisis de núcleos de formación

Abstract

The FICT petroleum laboratory does not have specialized equipment for determining capillary pressure in formation cores, which limits the development of advanced research. However, the centrifuge available for fluid separation has the potential to be adapted for petrophysical analysis in unconsolidated rock cores. This project aims to redesign the centrifuge to meet these needs. The development of the project included an initial operational evaluation to determine the status of the equipment and perform its proper maintenance. Based on this evaluation, it was proposed to change the motor for one capable of reaching 3010 RPM according to the properties of the fluids and the sandstone rock; as well as the design of new conical tubes and sample holders capable of withstanding mechanical stress, respecting the current dimensions of the equipment. In addition, a detailed cost analysis was carried out to determine the economic viability of the redesign. The results indicated that the total cost of the redesign was $1,551, representing a significant savings of 95% compared to the acquisition of new equipment valued at at least $30,000; demonstrating that the redesign would prove to be technically more feasible and functional for the project. In conclusion, the implementation of the redesign allows for the optimization of the use of available resources in the laboratory, and encourages the performance of future research without dependence on expensive equipment or external laboratories.
