Abstract

Método de perforación de un pozo que comprende los pasos de: hacer ingresar un conjunto de perforación que termina en un trépano en el interior de unaperforación; bombear un fluido de perforación con un contenido reducido de sólidos a travésdel conjunto de perforación con salida por el trépano,golpeando el fluido de perforación contra el material de la formación para desintegrarlo en cooperación con el trépano; bombear en forma continua unfluido de mayor densidad que el fluido deperf oración en el espacio anular entre la perforación y el conjunto de perforación mientras se perfora elmaterial de la formación, extendiéndose el fluido del espacio anular sustancialmente desde la superficie hasta la parteinferior del trépano; hacerretomar el fluido de perforación y los detritos resultantes de la desintegración del material de formación a la superficie a través de un pasajetubular sustancialmente sin obstrucciones del conjunto deperforación; y mantener al fluido del espacio anular bajo una presión seleccionada ycontrolada en el espacio anular, formándose una interfaz en el trépano, donde el fluido del espacio anular se mezcla con el fluido de perforación y retomajunto conel fluido de perforación y los detritos y sustancialmente se impide que el fluido de perforación ingrese en el espacio anular.
