Heutzutage ist die Aufrechterhaltung der Bohrlochstabilität eine sehr wichtige Aufgabe in der Bohrindustrie. Die Stabilität von Bohrlöchern kann durch die Entwicklung geeigneter Bohrspülungen verbessert werden. Aufgrund der Eigenschaften von Schieferformationen in Bezug auf ihre Ionenzusammensetzung, ihren Tongehalt und ihre sehr geringe Nano-Darcy-Durchlässigkeit mit sehr kleinen nanometergroßen Poren, die von den Feststoffen in herkömmlichen Bohrspülungen nicht effektiv abgedichtet werden, führt das Eindringen von Wasser in diese Art von Formationen zu vielen Problemen. Die Auswahl geeigneter Nanomaterialien mit geeigneter Partikelgröße und Konzentration zum Verschließen der nanogroßen Poren in den Schieferformationen ist der Schlüssel zur Verhinderung des Wasserflusses in die Schieferregion. Die Leistung und die rheologischen Eigenschaften von wasserbasiertem Schlamm werden durch die Bedeutung und die einzigartigen Eigenschaften von mehrwandigen Kohlenstoff-Nanoröhren (MWCNT) verbessert, wie z. B. eine thermische Stabilität von mehr als 600 °C, eine hohe chemische Stabilität, eine große Oberfläche, ein hohes Aspektverhältnis, ein geringes Gewicht, eine größere Flexibilität, eine hohe mechanische Festigkeit und hervorragende elektrische Eigenschaften.
