Description
En los campos petrolíferos de Colombia ocurre que, debido al arenamiento, se presenta corrosión, erosión y taponamiento de equipos y tuberías de superficie y de subsuelo, incrementando así la frecuencia de trabajos de intervención a los pozos productores de hidrocarburos. Dado lo anterior, surgió la necesidad de mejorar el módulo de control de arena, compuesto por dos herramientas del Manual General de Completamiento de Pozos ya existente (MGCP) para recomendar cuatro nuevas tecnologías de control de arena para su uso en yacimientos que presenten areniscas altamente no uniformes y rangos de tamaño de grano fino. Las mejoras introducidas a dicho módulo permitieron que dentro de la primera herramienta (matriz teórica para los campos de estudio) se recomendaran estas cuatro nuevas tecnologías para su uso en 22 de los 24 campos estudiados por autores previos, pertenecientes a cinco cuencas de Colombia. Así mismo, la segunda herramienta también fue actualizada mediante la introducción de las cuatro nuevas tecnologías mecánicas, además de incluirse un segundo parámetro de selección (tamaño de grano promedio) para recomendar el uso de tecnologías mecánicas nuevas o convencionales de control de arena con base en el último parámetro ya mencionado y en el ya existente coeficiente de uniformidad.
In Colombian oil fields it occurs that, due to the sanding, there is a corrosion, erosion and plugging of the equipment and the surface and subsoil pipes, thus increasing the frequency of intervention work in the hydrocarbon producing wells. Given the above, the need to improve the sand control module arose. This one is composed by two tools from the already existing General Manual of Wells Completion (MGCP), in order to recommend four new sand control technologies for their usage in reservoirs with both highly non-uniform sandstones and fine grain size ranges. The improvements introduced to this module allowed that within the first tool (theoretical matrix for the studied oilfields) these four new technologies were recommended for their usage in 22 of the 24 fields studied by previous authors, belonging to five Colombian basins. In addition, the second tool was updated by introducing these four new mechanic technologies and including a second selection parameter (average grain size) for recommending the use of an either new or conventional mechanic tool of sand control based on both the previously mentioned parameter and the already existing coefficient of uniformity.
