Abstract

"TéCNICA PARA DETECçãO DE SINAIS UTILIZANDO FILTRAGEM ADAPTáVEL DE TELEMETRIA DE PULSO DE LAMA". Um cancelador de ruído adaptável (ANC) de telemetria de pulso de lama é fornecido para prover informações sobre as condições de fundo de poço durante uma operação de Medindo Enquanto Perfurando / Registrando Enquanto Perfurando (MWD / LWD). O ANC emprega dois transdutores, cada um recebendo uma sucessão de sinais. Um transdutor primário, localizado furo abaixo tanto da bomba de lama quanto de um aliviador de sobrepressão, recebe um sinal primário. Um transdutor de referência, localizado próximo da bomba de lama e a montante do aliviador de sobrepressão, recebe um sinal de referência. O ANC relaciona linearmente o sinal de referência com o sinal primário por meio de um algoritmo de menores quadrados recorrentes e calcula os coeficientes de peso. O ANC utiliza os coeficientes de peso para processar um sinal primário subseq³ente, assim melhorando a transmissão dos dados de MWD / LWD.
