Abstract
Se presenta un método y aparato para la creacion de pozos secundarios multiples a partir de un pozo principal. Se proporciona un subensamble de ramificaciones multiples para su colocacion en un nodo de ramificacion de un pozo. Tal subensamble incluye una cámara de ramificacion y numerosos miembros de salida secundarios. Los miembros de salida durante la construccion de subensamble de ramificacion han sido ya distorsionados en formas ovaladas de tal manera que los miembros de salida de ramificacion quepan dentro de un cilindro imaginario coaxial y sustancialmente del mismo radio que la cámara de ramificacion. Después del despliegue de los conjuntos de ramificacion por medio de una tubería principal en el pozo, se baja una herramienta de conformacion hacia la parte interna del subensamble. Los miembros de salida se extienden hacia afuera por medio del empleo de la herramienta de conformacion y se forman simultáneamente en tubos sustancialmente redondos. Después, cada miembro de salida es taponeado con cemento, después de lo cual cada pozo secundario es perforado a través de un miembro de salida respectivo. Si se desea, cada pozo secundario puede estar revestido con tubería y sellado hasta una salida de ramificacion por medio de un colgador de tubería. Un multiple colocado en la cámara de ramificacion controla la produccion de cada pozo secundario hacia el pozo principal.
