Abstract
La presente invención se refiere a mejoras en método para medir la densidad de formaciones geológicas atravesadas por un pozo de sondeo, del tipo que comprende: irradiar la formación con rayos gamma; medir un primer coeficiente de conteo generado por los rayos que se han difundido principalmente en la formación y cuyas energías se han degradado generalmente por efecto Compton, a fin de producir una señal principal para calcular una densidad aproximada; medir un segundo coeficiente de conteo generado por los rayos que se han difundido principalmente en los materiales muy próximos al pozo de sondeo y cuyas energías se han degradado solo una vez por el efecto Compton, a fin de producir un a primera señal auxiliar para calcular una primera corrección de densidad relacionada con materiales inmediatamente adyacentes al pozo de sondeo, caracterizadas en que comprende además medir un tercer coeficiente de conteo generado por los rayos que se han difundido principalmente en los materiales próximos al pozo de sondeo, pero no próximos adyacentes a su pared, y cuyas energías se han degradado generalmente más de una vez por efecto Compton, a fin de producir una segunda señal auxiliar para calcular una segunda corrección de densidad relacionada con los últimos materiales.(VER FIGURA).
