Abstract
El presente invento se trata de un método e instrumento para determinar la desidad de una formacion, usando una serie de detectores de rayos gamma. Esteinvento puede corregir las considerables separaciones encontradas en pozos de sondeo de formai rregular y, en particular, las mayores separacionesencontradas típicamente por instrumentos tipo mandril. En este invento, los detectores colimados tienen profundidades de investigacion variables dentro dela formacion. En separacionespequenas, u n detector de corta distancia (DC) investiga principalmente el loo y costra de lodo y una capa superficial de laformacion. A diferencia del detector DC, un detector de distancia media (DM) tiene una mayor profundidad deinvestigacion y es sens ible al pozo de sondeo ya la formacion, incluso ante separaciones mayores. Un detector de larga distancia (DL) es sensible principalmente a la densidad de la formacion y sulectura de la densidad es corregida usando lainformacion de la separa cion de los detectores DM y DC. Además de medir la densidad, este invento puede medirel factor fotoeléctrico (FFE) de la formacion. Puesto que la absorcion fotoeléctrica elimina preferentemente los rayos gamma deenergía mínima, elalojamie nto del instrumento debe permitir el paso de rayos gamma de energía mínima.Esto se logra mediante el uso de una ventana compuesto de un materialcon bajonumero atomico (Z) o mediante el uso de un material para elalojamiento de bajo Z como el tita nio. Los materiales típicos de las ventanas son berilio ytitanio. Los materiales de alojamiento pueden ser titanio o para requisitos de baja presion, grafito o compuestos de carbono de alta resistencia.
