Abstract

"AGENTE DE INIBIçãO DE HIDRATAçãO DE XISTO E MéTODO DE USO DO MESMO". Um fluido de perfuração à base de água para uso em poços de perfuração através de uma formação que contém um xisto que intumesce na presença de água. o fluido de perfuração compreende de preferência: uma fase contínua à base de água; um material de peso e um agente de inibição de hidratação de xisto com a fórmula: H~ 2~N - CH (CH~ 3~) CH~ 2~ {-OCH~ 2~ CH (CH~ 3~)~ x~ -NH~ 2~ na qual X é um valor menor do que 15. O agente de inibição de hidratação de xisto deve estar presente em uma concentração suficiente para reduzir o intumescimento do xisto. De preferência X tem um número médio entre aproximadamente 1 e aproximadamente 5 e mais preferivelmente X tem um número médio de aproximadamente 2,6. Está também incluído na presente invenção um método de redução de intumescimento de argila de xisto encontrada durante a perfuração de um poço subterrâneo, o método compreendendo circular no poço um fluido de perfuração à base de água formulado de acordo com a presente invenção.
