Abstract

Se describe un sistema de disparo selectivo y un método para controlar las operaciones en un montaje de cadena de cañones que comprende cañones de perforación y auxiliares de interruptor conectados, de manera mecánica, en el montaje de cadena de cañones. Cada uno de los auxiliares de interruptor comprende además un elemento de conmutación, enlaces de entrada y enlaces de salida. Los auxiliares de interruptor y los cañones de perforación se comunican entre sí a través de los enlaces de entrada y salida. Los elementos de conmutación mantienen el seguimiento del estado de los estados del auxiliar e interruptores en función de las condiciones activadoras, tales como las condiciones ambientales, las condiciones del cañón de perforación, o las condiciones de entrada de la superficie. También se describe un método de autodetección para detectar fallas en un cañón de perforación y para actuar sobre la falla sin la necesidad de jalar o sacar el montaje de cadena de cañones del pozo. La figura más representativa de la invención es la número 1a.A selective firing system and method for controlling operations in a gun chain assembly is described comprising drill guns and switch auxiliaries mechanically connected to the gun chain assembly. Each of the switch auxiliaries further comprises a switching element, input links, and output links. The switch auxiliaries and drill guns communicate with each other via the input and output links. The switching elements keep track of the status of the auxiliary and switch states based on trigger conditions, such as environmental conditions, drill gun conditions, or surface input conditions. A self-sensing method is also described to detect faults in a drill gun and to act on the fault without the need to pull the gun chain assembly out of the hole. The most representative figure of the invention is number 1a.
