Abstract

Patente de Invenção: <B>"FLUIDOS VISCOSOS LIVRES DE SóLIDOS"<D>. A invenção fornece fluidos viscosos livres de sólidos (pílulas) para uso em várias operações de conclusão de trabalhos e de acabamento de poços incluindo como pílulas espaçadoras de deslocamento, pílulas de controle de perda de fluido, pílulas pós-recheio de pedregulhos-tela, selagem de perfuração, etc. As pílulas consistem em uma solução de um polietileno glicol tendo um peso molecular de 1000 a 8.000.000 num líquido aquoso contendo uma solução de um ou mais sais de brometo tendo uma densidade suficiente para proporcionar a desejada pressão hidrostática no local de uso do fluido num poço. A concentração mínima do polietileno glicol na pílula varia com o peso molecular médio como a seguir: PM - 1000 a 10.000 = 100 ppb; PM - 10.001 a 100.000 = 75 ppb; PM - 100.001 a 250.000 = 50 ppb; PM - 250.001 a 500.000 = 10 ppb; PM - 500.001 a 8.000.000 = 5 ppb.
