Abstract

resumo avaliação de cimento de fundo de poço com o uso de medições de nêutron pulsadas a estimativa de espaços vazios de cimento entre um revestimento e uma parede de furo de poço de um furo de poço que penetra a formação terrestre inclui formar, com um dispositivo de computação, uma razão real de radiação induzida por uma fonte de nêutron e medida por um primeiro detector e por um segundo detector quando a ferramenta está em dois ou mais locais diferentes no furo de poço. uma relação entre a razão real e a porosidade em cada um dentre os dois ou mais locais diferentes é usada e comparada com dois casos diferentes de estimativas da razão. com base na comparação, estimar os espaços vazios de cimento nos dois ou mais locais. 1/1
