Abstract

PROCESSO E SISTEMA PARA A DETERMINAçãO DO TAMANHO DE UM MATERIAL PENETRADO NO FURO DE SONDAGEM E PARA DETERMINAçãO DO TAMANHO DE UM FURO DE SONDAGEM Descreve um sistema para a medição do tamanho de um furo de sondagem penetrando uma formação de solo. O sistema utiliza uma fonte de nêutrons e pelo menos um detector de nêutrons. O detector de nêutrons responde primariamente ao teor de hidrogênio composto do material no interior do furo de sondagem e formação mediante irradiação pela fonte de nêutrons. Uma função de resposta por partição é utilizada para delinear a porção da resposta do detector resultante do furo de sondagem e a partir da formação. Uma vez que a resposta do detector a partir do furo de sondagem pode ser isolada utilizando-se a função de partição e o teor de hidrogênio do fluido do furo de sondagem é em geral conhecido, o tamanho do furo de sondagem pode ser determinado a partir da porção de resposta do furo de sondagem da resposta composta do detector caso combinada com uma medição da porosidade dos nêutrons da formação. A medição da porosidade dos nêutrons pode ser obtida independentemente, ou através da combinação da resposta do detector de nêutrons com a resposta de um segundo detector de nêutrons em um espaçamento axial diferente da fonte de nêutrons. O sistema sendo aplicável tanto nas operações com registrador na linha de fiação e registrador-enquanto-em-perfuração.
