Abstract

"MéTODO E APARELHO PARA UM ESPECTRÈMETRO A LASER DE DIODO SINTONIZáVEL PARA ANáLISE DE AMOSTRAS DE HIDROCARBONETO". A presente invenção refere-se a um aparelho e método no fundo do furo para a espectroscopia de ultra-alta resolução usando um laser de diodo sintonizável (TDL) para analisar uma amostra do fluido de formação no fundo do furo ou na superfície para determinar os parâmetros do fluido de formação. Além da espectroscopia de absorção, a presente invenção pode executar a espectroscopia Raman no fluido, varrendo o comprimento de onda do TDL e detectando a luz difundida por Raman usando um detector de faixa estreita em um comprimento de onda fixo. O espectrómetro analisa a amostra do fluido da perfuração de poço pressurizada que é coletada no fundo do furo. A análise é executada no fundo do furo ou no local na superfície. A análise de luz visível, perto do infravermelho e no meio do infraverme-lho é também executada na amostra para prover uma análise no local na superfície ou no fundo do furo das propriedades da amostra e nível de contaminação. A análise no local e no fundo do furo compreende a determinação de aromáticos, olefinas, saturados, razão de óleo gás, gravidade API e vários outros parâmetros que podem ser estimados pela correlação, uma rede neural treinada ou uma equação quimiométrica.
