Abstract

FLUIDOS DE PERFURAçãO. Reveladas aqui são composições de fluido de perfuração, e métodos de produzir e usar tais composições, segundo as quais as composições de fluido de perfuração incluem um fluido de base não-aquoso, uma mistura de um ou mais copolímeros, e polietileno. A mistura de copolímeros tem um peso molecular médio de cerca de 20.000 ou mais, e pode ser preparada reagindo pelo menos uma alfa-olefina, e pelo menos um anidrido de um ácido carboxílico alfa,beta-etilenicamente insaturado. O fluido de base não-aquoso é uma emulsão invertida baseada em óleo. O polietileno tem um índice de fusão menor que 10, e a granulometria média do polietileno é cerca de 0,15 cm ou menor.
