Abstract

"MéTODO PARA INFLUENCIAR A REOLOGIA DE UM FLUIDO DE PERFURAçãO OU FLUIDO DE MANUTENçãO DE POçO, FLUIDO DE PERFURAçãO OU FLUIDO DE MANUTENçãO DE POçO, E, MéTODO PARA REDUZIR A VISCOSIDADE DE UM FLUIDO DE PERFURAçãO OU FLUIDO DE MANUTENçãO DE POçO". Um método de reduzir a viscosidade de fluidos de perfuração e fluidos de manutenção de poço com base em óleo em temperaturas baixas e um composto diluente para o uso em tais fluidos de perfuração e fluidos de manutenção de poço são divulgados. O método compreende adicionar aos ditos fluidos de perfuração ou fluidos de manutenção de poço um diluente tendo a fórmula: R-(C~ 2~H~ 2~O),(C~ 3~H~ 6~O)~ m~(C~ 4~H~ 8~O)~ k~-H onde R é um radical alquila saturado ou insaturado, linear ou ramificado tendo cerca de 8 a cerca de 24 átomos de carbono, n é um número que varia de cerca de 1 a cerca de 10, m é um número que varia de cerca de 0 a cerca de 10 e k é um número que varia de cerca de 0 a cerca de 10.
