Abstract

"FLUIDO DE PERFURAçãO, EMULSIFICANTE, ADITIVO PARA A MELHORIA DAS PROPRIEDADES DE UMA EMULSãO INVERSA, MéTODO PARA A PERFURAçãO DE UM POçO EM UMA FORMAçãO SUBTERRâNEA, E, MéTODO PARA A MELHORIA OU A FACILITAçãO DA EMULSIFICAçãO, PARA A MELHORIA DAS PROPRIEDADES DE FILTRAçãO E PARA A MELHORIA DA ESTABILIDADE ELéTRICA DE UM FLUIDO DE PERFURAçãO BASEADO EM SINTéTICO OU óLEO OU DE UM FLUIDO DE PERFURAçãO COMPREENDENDO UMA EMULSãO INVERSA". Um método e um produto são descritos os quais proporcionam estabilidade de emulsão e controle de filtração aos fluidos de perfuração de emulsão inversa. O produto compreende uma mescla de uma poliamida terminada com ácido carboxílico e uma mistura produzida pela reação de Diels-Alder de dienófilos, preferivelmente ácidos carboxílicos, ácidos policarboxílicos, anidridos de ácido, ou combinações ou misturas dos mesmos, com uma mistura de ácidos graxos e ácidos resinosos. O produto é extremamente efetivo, diminuindo em cerca de dois terços a quantidade de emulsificante geralmente requerida para a formulação de um fluido de perfuração efetivo. O produto também reduz sobremaneira e em muitos casos elimina a necessidade de aditivos de perda de fluido convencionais, e adicionalmente proporciona estabilidade elétrica. Em adição, o produto possui um ponto de fluidez tão baixo quanto de cerca de -6,7<198>C com solventes mínimos, eliminando deste modo a necessidade de transporte de grandes quantidades de material inerte para uso, e pode ser transportado em um estado elevadamente ativo.
