Abstract

Patente de Invenção: <B>"USO DE áLCOOIS GRAXOS SELECIONADOS E MISTURAS DOS MESMOS COM éSTERES DE áCIDOS CARBOXìLICOS COMO COMPONENTE LUBRIFICANTE EM FLUIDOS DE PERFURAçãO à BASE DE áGUA PARA EXPLORAçãO GEOLóGICA"<D>. A invenção refere-se ao uso de álcoois graxos lineares e/ou ramificados contendo pelo menos 12 átomos de carbono na molécula e/ou ao uso de misturas de tais álcoois graxos com ésteres de ácidos carboxílicos como um aditivo lubrificante em fluidos de perfuração à base de água para seu uso em exploração geológica por perfuração. Os lubrificantes à base de álcool graxo ou sistemas lubrificantes são particularmente adequados para uso em lamas de perfuração de silicato de metal alcalino à base de água, que sabe-se serem disting³idos por valores de pH comparativamente elevados. Os aditivos de acordo com a invenção combinam seu efeito lubrificante com um efeito de supressão de espuma, isto é, evitam a espumação indesejada.
