Abstract
Un dispositivo para suministrar y distribuir fluidos de inyección al interior de una formación subterránea desde un pozo horizontal. El dispositivo incluye uno o más tubos para vapor con un manguito exterior y un manguito interior deslizante concéntricos. Hay uno o más conjuntos de boquillas dispuestas en el manguito exterior. Se provee un medio para accionar el desplazamiento del manguito interior deslizante dentro del manguito exterior, para cubrir por lo menos parcialmente uno o más de los conjuntos de boquillas que hay en el manguito exterior. También se provee un método para suministrar fluidos de inyección al interior de una formación subterránea desde un pozo horizontal. Primero, se introducen en el pozo horizontal uno o más tubos para vapor, donde dichos tubos para vapor tienen un manguito exterior y un manguito interior deslizante con uno o más conjuntos de boquillas dispuestas en el manguito exterior. Luego, se desplaza el manguito interior deslizante dentro del manguito exterior para cubrir por lo menos parcialmente uno o más de los conjuntos de boquillas que hay en el manguito exterior. Por último, se inyecta un fluido de inyección a través de las boquillas del tubo para vapor, dentro de la formación. Se contempla un método adicional, que comprende introducir en la localización del talón del pozo un primero y un segundo par de tubos colgantes para el control de flujo y receptáculos de diámetro interno pulido, conectados a una tubería de revestimiento intermedia y cementarlos en su lugar. El primer par de tubo colgante para el control de flujo y receptáculo de diámetro interno pulido se conecta a una tubería de revestimiento de inyección/extracción y luego se conectan uno o más tubos para vapor con el segundo par de tubo colgante para el control de flujo y receptáculo de diámetro interno pulido.A device for supplying and distributing injection fluids into an underground formation from a horizontal well. The device includes one or more steam pipes with an outer sleeve and a concentric sliding inner sleeve. There are one or more sets of nozzles arranged in the outer sleeve. A means is provided to drive the sliding inner sleeve displacement within the outer sleeve, to cover at least partially one or more of the nozzle assemblies that are in the outer sleeve. A method is also provided for supplying injection fluids into an underground formation from a horizontal well. First, one or more steam tubes are introduced into the horizontal well, where said steam tubes have an outer sleeve and a sliding inner sleeve with one or more nozzle assemblies arranged in the outer sleeve. Then, the sliding inner sleeve is moved into the outer sleeve to cover at least partially one or more of the nozzle assemblies in the outer sleeve. Finally, an injection fluid is injected through the nozzles of the steam tube, into the formation. An additional method is contemplated, which comprises introducing a first and a second pair of hanging tubes for flow control and polished internal diameter receptacles, connected to an intermediate casing pipe and cementing them in place. The first pair of pendant tube for flow control and polished internal diameter receptacle is connected to an injection / extraction liner pipe and then one or more steam pipes are connected to the second pair of pendant tube for flow control and polished internal diameter receptacle.
