Abstract

Se describe una columna (46) de la tubería aislada de pared doble, adaptada para ser suspendida de una cabeza (58) del pozo, que tiene una columna (21) de tubería interna, formada de varios tubos internos y una columna (22) de tubería radialmente externa, formada de varios tubos externos, la columnas de tuberías son independientes entre sí, además de fijas axialmente las columnas de tuberías una en relacion a la otra en el extremo superior de la columna de la tubería, aunque la fijacion axial también se puede proveer en el extremo inferior de las columnas de tuberías si se desea. Un espacio (30) aislante anular entre las columnas (21, 22) de tuberías se sella herméticamente en ambos extremos opuestos y puede ser evacuado. Las columnas de tuberías interna y externa se pueden poner en operacion en un pozo que utiliza tecnología de perforacion de pozo petrolero convencional y no hay conexion mecánica entre las columnas (21, 22) de tuberías interna y externa, especialmente en las conexiones de las respectivas longitudes interna y externa del tubo. Para mantener el interior de la columna (22) de la tubería externa libre de los líquidos de la formacion antes de que la columna (21) de la tubería interna se ponga en operacion en el pozo y se selle contra la columna de la tubería externa en su extremo inferior, un tapon temporal (31) cierra inicialmente el extremo inferior de la columna de la tubería externa y se desactiva de que el líquido pueda influir a través de la columna (46) de la tubería doble aislada térmicamente.
