Abstract

MÉTODO DE CALIBRAÇÃO DE BOMBINAS DE VARIAÇÃO H PARA MAGNETÔMETROS TRIAXIAIS. Trata-se de uma ferramenta direcional e de um método de inspeção de um poço de petróleo com a ferramenta direcional em uma coluna de poço. Um primeiro sensor da ferramenta direcional é disposto em um campo magnético ambiente não homogêneo. Um primeiro campo magnético aplicável é aplicado ao primeiro sensor. Uma primeira medição é obtida no primeiro sensor enquanto o primeiro sensor está imerso no campo magnético ambiente não homogêneo e com o primeiro campo magnético aplicável aplicado. Um segundo campo magnético aplicável é aplicado ao primeiro sensor. Uma segunda medição é obtida no primeiro sensor enquanto o primeiro sensor está imerso no campo magnético ambiente não homogêneo e com o segundo campo magnético aplicável aplicado. A ferramenta direcional é calibrada com base na primeira e na segunda medições. Uma medição de inspeção de fundo de poço é obtida com a ferramenta direcional calibrada disposta no poço de petróleo.
