Abstract

Un método para evaluar una densidad de las cortaduras durante la perforación un hoyo subterráneo incluye adquirir una primera y segunda mediciones de presión separadas axialmente en el hoyo. Las mediciones de la presión se pueden entonces procesar para obtener una densidad de intervalo del fluido de perforación entre las localizaciones de medición. Una sarta de herramientas que incluye un gran número de sensores de presión axialmente espaciados (por ejemplo, cuatro o más o incluso seis o más) acoplados electrónicamente con un procesador en la superficie mediante una tubería de perforación alambrada se puede usar para obtener una pluralidad de densidades de intervalo correspondiente con varios intervalos del hoyo. La densidad de intervalo se puede medir durante la perforación y se puede procesar además para calcular una densidad de las cortaduras en el espacio anular. Además, los cambios en la densidad de intervalo calculada con el paso del tiempo durante la perforación se pueden usar como un indicador de un cambio en la densidad de las cortaduras.
