Desenvolvimento de fluidos aquosos com bentonita para perfuração de poços de petróleo onshore

Abstract: Devido aos grandes desafios encontrados na perfuração de poços, há a necessidade de se desenvolver fluidos com propriedades adequadas e capazes de atender todas as exigências da perfuração, como elevada capacidade de carreamento de sólidos e alta lubricidade, como também fluidos ambientalmente corretos. O grau de impacto dos fluidos de perfuração no meio ambiente depende especialmente do tipo de fluido utilizado, se de base aquosa, oleosa, sintética ou mesmo de base ar. Portanto, é de fundamental importância o… Show more

“…This is because its composition and structure give it specific properties that make it useful in many different industrial applications, responsible for the movement of hundreds of millions of dollars in the global economy every year. Among these applications, this study draws attention to its use in drilling fluids [1,2]. Drilling fluids are primary suspensions of water and bentonite which play an essential role during the drilling of wells [3,4].…”

“…Na ausência de cisalhamento ou sob baixas taxas, as partículas de argilominerais estarão preferencialmente orientadas em formato de rede, nas quais as interações entre as folhas serão do tipo face-face (agregadas) ou face-aresta (floculadas). A partir do momento em que a taxa de cisalhamento aumenta, as folhas dos argilo-minerais tenderão a se orientar de maneira que facilite o fluxo, diminuindo a resistência ao movimento [13].…”
