style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;">La inyección de agua se ha convertido en uno de los procesos de recobro de petróleo más utilizado en el mundo. Sin embargo, esta puede llegar a ocasionar problemas como canalización del agua y bajas eficiencias de barrido vertical debido a la heterogeneidad del yacimiento, llevando al fracaso económico del proyecto. Por lo anterior, diversos autores han realizado estudios modificando la inyección de agua convencional, incluyendo el uso de pozos horizontales con el fin de mitigar los problemas mencionados. Esta tecnología denominada “Toe To Heel Waterflooding” (TTHW) clasificada como “short-distance”, ya que la distancia que recorre el crudo para ser producido es pequeña debido a la configuración de pozos, ocasionando a la vez una reducción en la caída de presión entre el pozo productor horizontal y el pozo inyector vertical, haciendo las fuerzas de gravedad más relevantes en el proceso.</span></p> <p class="Pa7" style="text-align: justify; line-height: normal;"><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;"> </span></p> <p class="Pa7" style="text-align: justify; line-height: normal;"><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;">En el presente trabajo se da a conocer un estudio a partir de modelos conceptuales de simulación del comportamiento de la inyección de agua usando pozos horizontales, con el fin de identificar los principales parámetros que inciden en el proceso y posteriormente determinar la factibilidad técnica del mismo en un modelo con propiedades de un campo Colombiano. Entre los parámetros evaluados se encuentran: Tasa de inyección, Permeabilidades, Viscosidad del crudo. Se realizó además un estudio comparativo entre la inyección de agua convencional y la tecnología TTHW determinando así las condiciones en las cuales el TTHW surge como alternativa para contrarrestar los efectos negativos en la inyección convencional. Por último se construyó un modelo conceptual estratificado con propiedades del campo Tello en cual se analiza el efecto de la segregación gravitacional.</span></p> <p class="Pa7" style="text-align: justify; line-height: normal;"><strong><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;"> </span></strong></p> <p class="Pa7" style="text-align: justify; line-height: normal;"><strong><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;">Palabras Clave: </span></strong><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;">TTHW, Inyección de agua, pozos horizontales, simulación numérica</span></p> <p class="Pa8" style="text-align: justify; line-height: normal;"><span style="font-size: 11pt; font-family: ";Calibri";,";sans-serif";;"> </span></p> <p class="Pa8" style="text-align: justify; line-height: normal;"><span style="font-size: 11pt; font-family: ";Calibri";,";sans-serif";;"> </span></p> <p class="Pa8" style="text-align: justify; line-height: normal;"><strong><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #404041;">ABSTRACT</span></strong></p> <p class="MsoNormal" style="margin-bottom: 0.0001pt; text-align: justify; line-height: normal;"><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;"> </span></p> <p class="MsoNormal" style="margin-bottom: 0.0001pt; text-align: justify; line-height: normal;"><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;">Waterflooding has been one of the most used oil recovery method around the world. However, this method may cause problems such as water channeling and low vertical sweep efficiency, due to reservoir heterogenety, carrying out the proyect economical failure. Previously, many authors have done studies over conventional waterflooding, using horizontal Wells in order to reudce the above problems. This technology called Toe To Heel Waterflooding (TTHW) has been classified as a short-distance, because the distance between the oil and the producer well is short due to the wells’ configuration generating a reduction of the pressures drop between the horizontal well and the vertical well, making the gravity forces more important in the process.</span></p> <p class="Pa7" style="text-align: justify; line-height: normal;"><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;"> </span></p> <p class="Pa7" style="text-align: justify; line-height: normal;"><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;">This work shows a study of conceptual models of simulation of waterflooding behavior by using horizontal Wells, in order to identify the principal parameters that affect the process and determine its technical factibility too, in a model with characteristics of a Colombian field. The evaluated parameters are: injection rate, permeabilities, oil viscosity; it was also done a comparative study between the conventional waterflooding and TTHW technology, identifying the conditions in which TTHW emerge as an alternative to counteract the negative results in the normal injection. Finally, it was built a layered conceptual reservoir with characteristics of Tello’s field, in which it is analyzed the effect of gravitational drainage.</span></p> <p class="MsoNormal" style="margin-bottom: 0.0001pt; text-align: justify; line-height: normal;"><strong><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;"> </span></strong></p> <p class="MsoNormal" style="margin-bottom: 0.0001pt; text-align: justify; line-height: normal;"><strong><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;">Keywords: </span></strong><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";; color: #221e1f;">Waterflooding, horizontal wells, TTHW, numerical simulation.</span><span style="font-size: 8.5pt; font-family: ";Verdana";,";sans-serif";;"></span></p>}, number={2}, journal={Fuentes, el reventón energético}, author={Yatte Garzon, Fabián Camilo and Villamizar Ballesteros, Ingrith Johana and Muñoz Navarro, Samuel Fernando and Londoño Galvis, Fernando Wilson and Maya Toro, Gustavo}, year={2009}, month={dic.} }
